Highlights of GAO-11-874, a report to congressional requesters. 

Why GAO Did This Study: 

The Census Bureau (Bureau) and U.S. Postal Service (USPS) collaborated 
on aspects of the 2010 Census and prior decennials, and those efforts 
generally went well in such areas as address list development. But 
both agencies face challenges: the Bureau needs to control the 
escalating cost of the decennial census and maintain its accuracy, 
while USPS must improve its financial condition. 

As requested, GAO examined opportunities to enhance collaboration in 
such areas as technology, personnel, and facilities that could improve 
the cost-effectiveness of the 2020 Census and generate revenue for 
USPS. GAO analyzed Bureau and USPS data and documents, compared the 
agencies’ existing collaborative efforts with prior GAO work, and 
interviewed agency officials. 

What GAO Found: 

The Bureau and USPS are expanding collaborative efforts for the 2020 
Census. The collaborative efforts include a new Bureau initiative to 
continuously update its master address list using USPS and local 
address information. This could allow the Bureau to limit the size of 
field operations needed to develop an accurate and complete address 
list for the 2020 Census. The Bureau and USPS also plan to update 
their 1995 memorandum of understanding to, among other matters, help 
ensure that both agencies benefit from their collaborative efforts. 
Bureau officials explained that under the 1995 memorandum, the agencies’
 collaboration typically benefited the Bureau more than USPS. Now both 
agencies would like to improve each other’s address and geographic 
information. One new effort anticipated under the revised memorandum 
of understanding would provide USPS with the Bureau’s geographic data 
products and support, which USPS hopes to use to improve its mail 
routing and other business decisions. The revised memorandum of 
understanding is expected to be approved later this year. 

Additional opportunities exist for the Bureau to take advantage of the 
knowledge and experience of USPS mail carriers, including retirees. 
Bureau and USPS officials agree that USPS mail carriers are familiar 
with their communities, so hiring mail carriers as temporary census 
workers could allow the Bureau to, among other things, develop a more 
accurate address list for the 2020 Census. However, using mail 
carriers to conduct census field operations at USPS pay rates would 
not be cost-effective. In 2010, USPS mail carriers cost on average 
about $41 (city) or $34 (rural) per hour compared to about $15 per 
hour for census enumerators. 

In the 2010 Census, about 19-million forms could not be delivered—also 
known as undeliverable as addressed mailings. The Bureau, in its 
comments to a copy of this draft report, provided a summary of reasons 
for why forms were not delivered. These reasons include the house was 
vacant or there was no mail box. Thus, now that the Bureau has 
compiled this information, it will be important for the Bureau to work 
with USPS to assess strategies to reduce the number of undeliverable 
as addressed mailings, as undelivered mail results in additional 
operational and waste-disposal costs for USPS and additional postage 
fees for the Bureau. 

The Bureau works with the General Services Administration to lease 
space for its local offices during the census. For the 2010 Census, 
the Bureau leased two USPS locations for a total cost of $330,000. 
While USPS officials stated that ongoing efforts to downsize the USPS 
could increase the availability of facility space that could be used 
by the Bureau in the next census, USPS hopes to sell these facilities, 
and it is uncertain how many will be available in 2020 (and what 
condition those facilities would be in if they were available). 

What GAO Recommends: 

GAO recommends the Secretary of Commerce and USPS consider (1) 
expanding their current collaborative efforts to include recruiting 
mail carriers, including retirees, for the 2020 Census, and (2) 
assessing whether strategies can be developed to reduce the number of 
“undeliverable as addressed” census mailings. USPS agreed with GAO’s 
recommendations. Commerce disagreed with the second draft 
recommendation concerning analyzing the reasons for undelivered 
mailings. GAO revised the recommendation to focus on developing a 
strategy to help reduce costs involved with processing undelivered 
mail.

September 30, 2011: 

The Honorable Stephen F. Lynch:
Ranking Member:
Subcommittee on Federal Workforce, U.S. Postal Service and Labor Policy:
Committee on Oversight and Government Reform:
House of Representatives: 

The Honorable Jason Chaffetz:
House of Representatives: 

In some respects, the U.S. Census Bureau (Bureau) and U.S. Postal 
Service (USPS) are operationally similar in that they fulfill their 
missions by processing large amounts of paper, delivering it to 
millions of housing units across the country, and employing a large 
workforce. Additionally, both agencies face unique financial and 
management challenges. The Bureau has the challenge of controlling the 
escalating cost of the decennial census--especially of field 
operations--while maintaining its accuracy. The 2010 Census cost about 
$13 billion (almost $5 billion more than the 2000 Census--in 2010 
dollars) and was the most expensive population count in our nation's 
history. At the same time, while USPS has achieved cost savings in the 
last 5 years, its financial condition has deteriorated significantly 
since fiscal year 2006, and its financial outlook is grim in both the 
short and long term. USPS has been experiencing billion-dollar losses 
and cash shortfalls over the last 5 years, and expects to reach its 
$15-billion borrowing limit[Footnote 1] this fiscal year. In addition, 
on June 22, 2011, USPS officials announced that USPS will suspend its 
employer's contributions for the defined benefit portion of the 
Federal Employees Retirement System in order to conserve cash and 
preserve liquidity. The following month USPS announced it planned to 
study the closure of approximately 3,700 retail offices. We have 
reported extensively on the feasibility of USPS increasing revenue and 
remaining viable in the face of declining mail volumes resulting from 
the recession and the continuing shift to electronic communication 
alternatives.[Footnote 2] For these and other reasons, in 2009, we 
placed USPS's financial condition and outlook on our list of high-risk 
programs and agencies.[Footnote 3] 

The Bureau and USPS collaborated on aspects of the 2010 Census and 
prior decennials, and those efforts generally went well. At your 
request, we examined planned and unexplored opportunities to enhance 
collaboration in such areas as technology, personnel, and facilities 
that could improve the cost-effectiveness of census operations for the 
2020 Census and possibly generate revenue for USPS. 

To collect data and information for this report, we reviewed relevant 
documents, including the agencies' documentation of lessons learned 
from the 2010 Census, and we interviewed agency officials to identify 
current and planned collaborative activities. To determine existing 
and unexplored technological efforts that could be shared between the 
agencies, we reviewed relevant documents including agency strategic 
plans, interviewed agency officials about current practices such as 
the Intelligent Mail Barcode, and visited a mail distribution center 
in Baltimore, Maryland, to understand how 2010 Census mail pieces 
would have been shipped and received and whether there could be 
improvements to that process for the 2020 Census. To determine whether 
there were opportunities for additional collaboration for personnel, 
we examined 2010 Census hiring data from the Bureau and we interviewed 
agency officials and USPS labor union representatives to discuss the 
hiring of mail carriers as temporary census workers. To determine 
whether additional collaboration between USPS and the Bureau could 
include more uses of physical assets, we examined 2010 Census leasing 
documents and interviewed officials from the Bureau, USPS, and the 
General Services Administration (GSA). Finally, we compared the 
agencies' existing collaborative efforts to key practices we 
identified in prior GAO work regarding sustaining and enhancing cross-
agency collaboration[Footnote 4]. 

We conducted this performance audit from December 2010 through 
September 2011 in accordance with generally accepted government 
auditing standards. Those standards require that we plan and perform 
the audits to obtain sufficient, appropriate evidence to provide a 
reasonable basis for our findings and conclusions based on our audit 
objective. We believe that the evidence obtained provides a reasonable 
basis for our findings and conclusions based on our audit objective. 

Background: 

The decennial census is a constitutionally mandated undertaking that 
is used, among other things, to apportion seats in Congress, redraw 
congressional districts, help annually allocate billions of dollars in 
federal aid to state and local governments, and inform investment 
decisions by the public and private sectors. As shown in figure 1, the 
cost of enumerating each housing unit has escalated from around $16 in 
1970 to around $97 in 2010, in constant 2010 dollars (an increase of 
over 500 percent). Costs are driven in part by, the mail response rate-
-a key indicator of a cost-effective census--which has declined from 
78 percent in 1970 to 63 percent in 2010. A variety of factors account 
for the declining response rate, including increases in non-English 
speakers and people residing in makeshift and other nontraditional 
living arrangements. Given these and other sociodemographic 
challenges, the Bureau has been investing substantially more resources 
each decade just to try and match the results of prior enumerations.

2010 Dollars) Has Escalated Each Decade, While Mail Response Rates

2010 Census are not yet final. 

Note: In the 2010 Census the Bureau used only a short-form 
questionnaire. For this report we use the 1990 and 2000 Census short- 
form mail response rate when comparing 1990, 2000, and 2010 mail-back 
response rates. Census short-form mail response rates are unavailable 
for 1970 and 1980, so we use the overall response rate.

[End of figure] 

According to the Bureau, several factors were behind the escalating 
costs of the 2010 Census, such as the need to hire about 585,000 
temporary field staff to count the more than 46-million households 
that did not mail back their census forms, and substantial investments 
in updating the Bureau's address list--including address canvassing, a 
door-to-door effort to verify the address list's accuracy in 2009. 

USPS also faces financial challenges, especially as customers shift to 
electronic communications and electronic payments. Total mail volume 
peaked in fiscal year 2006 at 213-billion mail pieces and is expected 
to decline by about 22 percent by the end of fiscal year 2011, to 
about 167-billion mail pieces. In the first three quarters of this 
fiscal year, the volume for First-Class Mail--USPS's most profitable 
product--declined by 6.5 percent compared to the same period last 
year. Over the last 5 fiscal years, USPS has experienced a cumulative 
net loss of nearly $23 billion, and has already reported a net loss of 
nearly $5.7 billion through the first nine months of fiscal year 2011. 
Further, USPS anticipates ending this fiscal year with a loss of 
approximately $10 billion. 

USPS plays a key role in the success of the decennial census. Since 
the advent of the mail-out/mail-back census in 1970, USPS has helped 
to develop and improve the Bureau's census address list and has 
delivered and returned census forms. A complete and accurate address 
list is the cornerstone of a successful census because it both 
identifies all households that receive a census questionnaire and 
serves as the control mechanism for following up with individuals at 
households that fail to respond. USPS maintains and regularly updates 
a database (its Delivery Sequence File) of all addresses to which it 
delivers mail and provides this information biannually to the Bureau. 

The collaborative efforts between the Bureau and USPS have generally 
gone well and demonstrate the importance of key leading collaboration 
practices that we previously identified.[Footnote 5] Some of these 
include: 

* establishing compatible policies, procedures, and other means to 
operate across agency boundaries; 

* defining and articulating a common outcome; and: 

* identifying and addressing needs by leveraging resources. 

* For example, in 1990, the Bureau and USPS established the 
interagency Joint Committee for Census Planning to develop 
opportunities for cooperation in support of the decennial census. This 
committee defines and agrees on the respective roles and 
responsibilities of the two agencies and addresses the compatibility 
of standards and policies. In 1995, USPS and the Bureau signed a 
memorandum of understanding that is still in effect which defined how 
the two agencies will share addresses in order to conduct the 
decennial census. Moreover, for the 2010 Census the agencies agreed to 
have USPS destroy rather than return certain undeliverable mail 
pieces, resulting in cost savings of $250,000 for the Bureau and over 
$12 million in savings for USPS, according to Bureau estimates. 

* Officials from both the Bureau and USPS believe their collaboration 
related to the 2010 Census was mutually beneficial. For example, 
Bureau officials stated that USPS delivered 417-million census mail 
pieces, virtually 100 percent of which were delivered on time, and 
according to USPS's 2010 Comprehensive Statement on Postal Operations, 
census mailings generated over $202 million in revenue. Additionally, 
the 2010 Census provided USPS with an opportunity to demonstrate the 
benefits of a relatively new mail product, the Intelligent Mail 
Barcode, which enables mailers to track the progress of their mail 
through the many stages of processing to delivery. The Bureau was the 
largest-ever user of Intelligent Mail Barcode for a single-mailing 
effort, and the success of the mailing could help USPS market the 
barcode to other customers. Among other benefits, the barcode enabled 
the Bureau to identify which census forms were in the mail-stream on 
their way back to the Bureau 3 to 5 days sooner than if the Bureau had 
not used this technology (see figure 2). As a result, the Bureau was 
able to remove 11 million addresses from the replacement mailing, 
which led to nearly $5 million in postage savings.[Footnote 6] 

Figure 2: Example of a Mail Piece Containing an Intelligent Mail 
Barcode and Bureau Benefits: 

[Refer to PDF for image: illustration of envelope] 

Intended Bureau Benefits: 

* Increased efficiency and reduced costs; 
* Reduced amount of undeliverable as addressed mail; 
* Better service information; 
* Price reductions and other benefits for the Bureau.

Opportunities Exist to Enhance the Partnership between the Bureau and 
USPS: 

The Bureau and USPS Plan Additional Collaborative Efforts for the 2020 
Census: 

The Bureau and USPS are engaging in efforts to enhance their 
collaboration. For example, given the Bureau's use of the Intelligent 
Mail Barcode for the 2010 Census, the Bureau considered using the 
barcode for its American Community Survey.[Footnote 7] Although Bureau 
officials indicated they planned to use the Intelligent Mail Barcode 
for the American Community Survey, since the completion of our audit, 
the Bureau determined that the cost savings were insufficient to 
justify the required investment to use the technology. 

The Bureau is in the planning stages of working with USPS and other 
federal agencies on a new program called the Geographic Support System 
Initiative, which is intended to allow government agencies at all 
levels to regularly share and continuously update their address lists, 
making them more detailed and accurate. Specifically, the Bureau plans 
to partner with USPS and other federal agencies as well as 
approximately 40,000 tribal, state, and local governments. According 
to current plans, USPS will continue providing the Bureau with 
addresses from its Delivery Sequence File. Likewise, tribal, state, 
and local governments, which maintain address lists for purposes such 
as emergency response and property assessment, will have the 
opportunity to share addresses with the Bureau throughout the decade, 
rather than solely 2 years prior to the decennial, as had been the 
case in prior decennials. However, Bureau officials have noted that in 
moving forward one challenge will be coordinating adherence to the 
confidentiality protections included in the Bureau's Title 13 
provisions and USPS's Title 39.[Footnote 8] Ultimately, by leveraging 
address information from USPS and other government entities during the 
non-decennial years, Bureau officials anticipate that they will be in 
a position in 2019 to move away from a full door-to-door address 
canvassing of every housing unit, to a more targeted effort.[Footnote 
9] Address canvassing is one of the Bureau's largest and most 
expensive field operations, and Bureau officials stated a more 
targeted program could lead to significant cost savings. 

The Bureau and USPS also plan to update their 1995 memorandum of 
understanding to, among other matters, reflect routine changes that 
have occurred over time (e.g., update contact information), and help 
ensure that both agencies benefit from their collaborative efforts. 
Bureau officials explained that under the 1995 memorandum, the 
agencies' collaboration typically benefited the Bureau more than USPS. 
Now both agencies would like to improve each other's address and 
geographic information. One new effort anticipated under the revised 
memorandum of understanding would provide USPS with the Bureau's 
geographic data products and support, which USPS hopes to use to 
improve its mail routing and other business decisions. The revised 
memorandum of understanding is expected to be approved later this year. 

The Bureau Could Better Leverage USPS Local Knowledge by Recruiting 
USPS Mail Carriers to Work Temporarily for the Census: 

Opportunities exist for the Bureau to take advantage of the knowledge 
and experience of USPS mail carriers, including retirees. Bureau and 
USPS officials agree that USPS city and rural mail carriers are 
familiar with the local living conditions in their communities and 
that this knowledge could help the Bureau conduct aspects of the 2020 
Census more effectively. Mail carriers have experience and knowledge 
about the dwellings on their routes and could help find unconventional 
and hidden housing units (e.g., converted basements and attics) and 
identify single versus multi-unit homes. Residents of these households 
are often more difficult to find and count. Additionally, in some 
communities, mail carriers have information about hazardous locations 
along delivery routes (e.g., houses with an unchained dog or other 
dangers such as structurally unsafe porches), which could make census 
workers' jobs safer and easier. 

In hiring for the 2010 Census, the Bureau did not do a targeted 
recruitment of USPS employees and retirees, a potential missed 
opportunity given that there were approximately 300,000 USPS mail 
carriers and approximately 100,000 additional retired mail carriers at 
that time.[Footnote 10] Still, the Bureau hired approximately 2,400 
USPS employees as temporary census employees at the Bureau's $15 
average pay rate.[Footnote 11] The potential benefits of mail 
carriers' local knowledge was evident, for example, in a case we 
observed in Louisiana, where a retired mail carrier used his knowledge 
of local living conditions to successfully manage census field 
operations in the area most devastated by Hurricane Katrina. 
Specifically, the mail carrier knew which addresses to remove and 
which to add to the address list based on his experience delivering 
mail in those neighborhoods. In moving forward for 2020, a targeted 
campaign--e.g., via job listings in mail carrier union newsletters and 
publications--could help the Bureau recruit more mail carriers to 
conduct census operations. 

That said, using full-time mail carriers paid at much higher USPS wage 
rates--either for additional duties during the work day or as part of 
a "postal holiday" (where regular mail operations would be suspended 
in order to conduct census activities)--would not be cost-effective. 
Regarding cost, in 2010, the average USPS mail carrier was paid about 
$41 (city) or $34 (rural) per hour including benefits for regular time 
worked, compared to the average hourly pay of about $15 paid to census 
enumerators. Moreover, in conducting the 2010 Census, it took about 45 
million staff hours to contact nonrespondents. Because of the 
difference in pay rates and the large number of staff hours involved, 
it would not be practical for mail carriers to perform census duties 
in lieu of census workers because of the higher costs and disruption 
it would cause to U.S. mail service. 

Reducing the Number of "Undeliverable as Addressed" Mailings Could 
Improve the Efficiency and Cost-Effectiveness of USPS Operations: 

During the 2010 Census, USPS personnel were concerned about resources 
spent attempting to deliver census mailings with undeliverable 
addresses. Bureau officials initially noted that the roughly 19-
million undelivered forms were higher than the 12-million 
undeliverable forms anticipated. According to officials from both 
agencies, the different purposes of their address lists contributes to 
undeliverable mailings; the Bureau's Master Address File supports the 
mission of counting everyone in the nation and contains all addresses, 
vacant or occupied, where someone may reside. However, USPS does not 
support the delivery of mail to vacant housing units. Indeed, 
preliminary data confirms that some 53 percent of undelivered forms 
were because of housing units being vacant. 

According to the Bureau the difference between the 19-million and the 
12-million undeliverable forms was primarily due to replacement 
mailing forms that were sent to nonresponding households, and not 
because of an increase in its initial projection that approximately 12-
million addresses would be undeliverable. Nevertheless, while the 
Bureau is able to explain the difference between the actual and 
projected number of undelivered forms, the data still show that USPS 
processed a significant number of forms--19-million (the initial mail 
out of forms went to approximately 120-million addresses). In a 
subsequent conversation, Bureau officials agreed that in looking 
forward to 2020, it would be beneficial to both agencies to research 
ways to reduce the number of undeliverable forms. Indeed, one such 
example to reduce the undeliverable workload was highlighted in a 
Census lessons-learned document dated June 2010. In that document, it 
was recommended that addresses that do not have a city or state be 
eliminated from the address list provided to USPS. However, the Bureau 
will still need to determine how it will get a census form to those 
housing units. 

In responding to a copy of our draft report the Bureau provided a 
summary of preliminary reason codes for why approximately 12-million 
initial forms were not delivered. Thus, now that the Bureau has 
compiled this information it will be important for the Bureau to work 
with USPS to assess whether strategies can be developed to reduce the 
number of undeliverable as addressed mailings such as not delivering 
to housing units that do not have a complete address or that do not 
have a mail box. Given the fiscal situation of USPS, reducing the 
undeliverable workload is important because these mailings incur 
additional operational and waste-disposal costs for USPS and 
additional postage fees for the Bureau. 

Various Factors Could Affect the Bureau's Use of USPS Facilities in 
2020: 

For the 2010 Census, the Bureau operated 494 local census offices 
across the country. The Bureau works with GSA to identify, convert, 
and lease space for its local offices during the census. When 
identifying space, GSA's policy is to first search its property 
database for government and USPS-owned facilities, and if none are 
available to then turn to commercial facilities. For the 2010 Census, 
the Bureau leased ten government-owned facilities and two USPS 
facilities: one in Waycross, Georgia, and the other in Johnstown, 
Pennsylvania. USPS received $196,990 on the 16-month lease of the 
facility in Waycross, Georgia, and $132,702 on the 14-month lease in 
Johnstown, Pennsylvania. The Bureau's requirements for office space 
included a minimum of 6,197 square feet in specific locations across 
the country, and a short fixed time period. GSA officials stated that 
difficulty in meeting these requirements was the principal reason why 
the Bureau leased very few government and USPS-owned facilities. USPS 
officials stated that ongoing efforts to downsize USPS will probably 
increase availability of facility space that could be used by the 
Bureau in the next census, but USPS hopes to sell these facilities, 
and it is uncertain how many will be available in 2020 (and what 
condition those facilities would be in if they were available). 
Additionally, Bureau officials have not determined how many local 
census offices will be needed for 2020 or where they will need to be 
located. These and other unknown factors, such as potential changes to 
Bureau requirements, could affect the Bureau's need to lease space 
from USPS in 2020. 

Conclusions: 

Bureau and USPS collaboration is important to achieving a complete and 
accurate census. While such collaboration is unlikely to lead to 
significant new funds for USPS, it could make aspects of the census 
more cost-effective. To that end, the Bureau and USPS have undertaken, 
and are currently engaging in, efforts to enhance collaboration that 
will likely result in more efficient mailings and more detailed and 
accurate address lists. Additionally, by updating the 1995 memorandum 
of understanding, the Bureau and USPS will help ensure that both 
agencies benefit from their collaborative efforts. However, because of 
potential changes to the design of the decennial census and USPS's 
financial condition, it is difficult to predict how the Bureau and 
USPS's collaboration will evolve for the 2020 Census. 

Building upon the success of current and past partnership efforts, 
opportunities exist to enhance the Bureau and USPS's collaborative 
efforts. First, the Bureau could better leverage USPS local knowledge 
and tap into a large labor pool by doing targeted recruitment of USPS 
mail carriers, including retirees, to work temporarily for the census. 
Second, during the 2010 Census, USPS spent time and money attempting 
to deliver millions of census mailings that were returned as 
undeliverable. A focus on solutions for delivering census forms to 
addresses where the Bureau does not have a complete address could 
decrease USPS's operational and waste-disposal costs. 

Recommendations for Executive Action: 

Given the importance of Bureau and USPS collaboration in successfully 
executing census operations, as part of future partnership activities, 
we recommend that the Postmaster General and the Secretary of Commerce 
direct their agencies to expand their collaborative efforts by: 

* determining if there are ways that the Bureau could work with USPS 
to target recruitment opportunities to mail carriers, and: 

* assessing whether strategies can be developed to reduce the number 
of undeliverable as addressed mailings. 

Agency Comments and Our Evaluation: 

On August 24, 2011 we sent a draft of this report to USPS and on 
September 15, 2011, the Vice President of Product Information at USPS 
provided written comments that are reprinted in appendix I. USPS 
generally agreed with the overall findings and recommendations of the 
report. In regards to better leveraging USPS local knowledge by 
recruiting mail carriers to work temporarily for the Census, USPS 
agreed that this may be an opportunity to help the Census Bureau 
conduct aspects of the 2020 Census, so long as the work did not 
disrupt mail service. Moreover, USPS agreed that reducing the number 
of undeliverable mailings will reduce USPS operational costs, and 
stated that it will work with the Bureau through the interagency joint 
committee to develop strategies to reduce them in future mailings. 

Additionally, on August 24, 2011 we sent a draft of this report to the 
Department of Commerce and the Bureau and on September 15, 2011, the 
Acting Secretary of Commerce provided written comments from the Census 
Bureau. Those comments are reprinted in appendix II. The Bureau in its 
comments was silent on whether it agreed with the recommendation to 
target recruitment opportunities to mail carriers, however, in a 
subsequent discussion stated that it did agree with that first 
recommendation. The Bureau disagreed with the finding and 
recommendation for reducing the undeliverable as addressed mailing 
workload, stating they had already analyzed the available reasons for 
why mailings were undeliverable and because the number of unique 
addresses that were undeliverable did not vary substantially from 
Bureau projections. Further, the Bureau provided additional 
information related to one of our findings that we incorporated into 
the report, as appropriate. Specifically, the Bureau informed us that 
since the completion of our audit work, it has opted not to use the 
Intelligent Mail Barcode in its American Community Survey. This new 
information is reflected in the body of the report. In the comments, 
the Bureau also included an attachment of analysis that was not 
reprinted in this report because the data were still in draft. 

The Bureau noted that our report, in its discussion of undeliverable 
as addressed mailings, implies that the majority of these mailings 
were the result of invalid addresses. Our draft report did not intend 
to imply that the majority of undeliverable as addressed mailings were 
the result of invalid addresses. In fact, our report emphasizes that 
the different purposes of the address lists for USPS and the Census 
Bureau contributed to the many undeliverable mailings. We have revised 
the language in the finding to further clarify this point. 

The Bureau stated that our report also implies that the Bureau 
underestimated the number of undeliverable as addressed mailings by 7 
million because of a miscommunication between the Census and USPS. 
Specifically, the Bureau in its response to our draft report 
acknowledges that it never clearly communicated to USPS that 
undeliverable mailings would be higher than the number of 
undeliverable addresses. According to Bureau officials, this is 
because undeliverable addresses receive multiple mailings. We 
understand that it was 12 million addresses that contributed to the 19-
million undeliverable forms; however, we believe our point to reduce 
the number of undeliverable mailings is still valid because USPS still 
had to process and attempt to deliver 19-million forms. In a 
subsequent conversation Bureau officials agreed that finding ways to 
reduce undeliverable mailings would benefit both agencies. We have 
revised this section of the report. 

The Bureau believes much of the undeliverable as addressed operational 
and waste-disposal costs for USPS and additional postage fees for the 
Bureau were both anticipated and unavoidable. However, we believe that 
if the Bureau can reduce the number of undeliverable as addressed 
mailings, then it can avoid the cost to process forms that can not be 
delivered. For example, in a Census lessons-learned document dated 
June 2010, it was recommended that one way to reduce the undeliverable 
as addressed workload would be to eliminate addresses that did not 
have a city or state. We believe that steps to reduce the 
undeliverable as addressed workload, such as the one highlighted in 
the lessons-learned document, can prevent USPS from incurring 
unnecessary operational and waste-disposal cost and the Bureau from 
incurring unnecessary postage fees. 

Finally, the Bureau disagreed with our recommendation to analyze the 
reasons why there were more undeliverable as addressed mailings than 
expected and to develop strategies and procedures to reduce them, 
because according to the Bureau, it has analyzed the reasons why 
mailings were undeliverable and the number of "unique" addresses that 
were undeliverable did not vary substantially from its projections. We 
believe that there are opportunities to reduce undeliverable mailings. 
We have revised our recommendation so it now reads that the Bureau 
"assess whether strategies can be developed to reduce the number of 
undeliverable as addressed mailings." This change recognizes that the 
Bureau has compiled the information to understand the various reasons 
why there were so many undelivered forms and can now use that data to 
assess whether strategies can be developed to reduce the number of 
undeliverable as addressed mailings.

Mr. Robert Goldenkoff: 
Director, Strategic Issues: 
United States Government Accountability Office: 
Washington DC 20548-0001: 

Dear Mr. Goldenkoff, 

This letter is in response to the draft report titled 'Census Bureau 
and Postal Service Should Pursue Opportunities to Further Enhance 
Collaboration' cosigned by Mr. Phillip Herr. 

As indicated in your draft report, the Postal Service agrees that the 
collaboration between the Census Bureau and the USPS for the decennial 
2010 census went generally well. We will continue to work 
collaboratively through the interagency Joint Committee for Census 
Planning in preparation for the decennial 2020 census. We also agree 
that working with the Census Bureau in improving the informational 
share of addressing information between both organizations through a 
revised Memorandum of Understanding would be mutually beneficial. 

In regards to better leveraging USPS local knowledge by recruiting 
USPS mail carriers, both active and retired employees, to work 
temporarily for the Census; we agree that this may be an opportunity 
to help the Census Bureau conduct aspects of the 2020 Census more 
effectively and potentially safer. However, as you also note in your 
draft, it is imperative that this activity does not create disruption 
in mail service. We will work with the Census Bureau through the 
interagency Joint Committee to determine if there are ways to 
facilitate this activity as we progress towards the decennial 2020 
census. 

In regards to reducing the number of "Undeliverable as Addressed" 
mail, improving the efficiency and cost-effectiveness of USPS 
operations; we agree that reducing the number of Undeliverable as 
Addressed mailpieces will reduce USPS operational cost and postage 
fees for the Census Bureau. Again, we will work with the Census Bureau 
through the interagency joint committee to analyze the causes behind 
more undeliverable as addressed mail than expected and develop 
strategies to reduce them in future mailings. 

If I can be of any further assistance, or provide you with any further 
information, please do not hesitate to contact me at 202-268-7458 or 
via email at Jim.P.Cochrane@usps.gov. 

Sincerely, 

Signed by: 

James P. Cochrane

U.S. Department of Commerce Comments on the U.S. Government 
Accountability Office Draft Report titled 'Decennial Census: Census 
Bureau and Postal Service Should Pursue Opportunities to Further 
Enhance Collaboration' (GA0-11-874): 

September 2011: 

The U.S. Census Bureau would like to thank the U.S. Government 
Accountability Office (GAO) for its efforts in examining the ways in 
which the Census Bureau collaborated with the United States Postal 
Service (USPS) during the 2010 Census in order to ascertain enhanced 
ways to improve the efficiency and cost-effectiveness of the next 
decennial census. 

The Census Bureau provided a few comments about statements and 
conclusions in this report. 

* Page 6, last paragraph: The Bureau and USPS are engaging in efforts 
to enhance their collaboration. For example, given the Bureau's 
success using the Intelligent Mail Barcode for the 2010 Census, the 
Bureau conducted a business case which outlined the potential benefits 
of using the barcode for its American Community Survey. 

Census Bureau response: Since our discussion with auditors about the 
business case to employ Intelligent Mail Barcode in order to reduce 
the second questionnaire mailings, the Census Bureau received the 
results of its ACS Internet Test. Based on those results and our 
planned internet implementation in 2013, it appears likely that there 
would not be sufficient harvestable savings to pay off the Improving 
Operational Efficiency (IOE) required investment; therefore, all work 
on the IOE for postal tracking was stopped. 

* Page 7, footnote 8: 13 U.S.C. generally prohibits the Bureau from 
disclosing data it collects about individuals...information with the 
Bureau. 

Census Bureau response: The word "generally" should be stricken from 
this footnote. "Generally" implies that an action is normally, usually 
or "by and large" taken; thus, the word "generally" implies a lesser 
degree of observance or adherence to an action or rule. Therefore, 
using this terminology to describe prohibitions against the disclosure 
of data collected by or on behalf of respondents under the provisions 
of Title 13 is not consistent with the strong protections afforded by 
13 U.S.C. Section 9. Section 9 does not provide for a "general 
prohibition," but a very clear mandate of confidentiality. Section 9 
may have exceptions, but the exceptions are extremely narrow and 
nondisclosure is mandatory when the exceptions do not apply. 

* Page 10: Reducing the Number of "Undeliverable as Addressed" [UAA] 
Mailings Could Improve the Efficiency and Cost-Effectiveness of USPS 
Operations 

Census Bureau response: The Census Bureau is concerned that this 
statement, along with its accompanying discussion, could imply that 
the majority of UAA mailings were the result of invalid addresses. 
While some of the UAA mailings were due to invalid addresses, the 
overwhelming majority of UAA mailings were cases of valid addresses 
that were vacant units (53.42%) or where there was no mail receptacle 
to deposit the mail (15.11%). The attached breakdown of UAA Reason 
Codes provides further detail and this data was provided by USPS. This 
section of the report implies that the Census Bureau underestimated 
the number of UAA mailings by 7 million because of a miscommunication 
between the Census Bureau and USPS. However, the actual number of 
unique UAA mailing addresses was only 400,000 greater than the 
original Census Bureau estimate of 12 million. The Census Bureau does, 
however, acknowledge that its initial projection of 12 million UAAs 
was never clearly communicated to the USPS as 12 million unique 
"addresses" that would be undeliverable versus a much higher number of 
"mailings" that would be undeliverable. 

While the accompanying discussion to this finding notes that the UAA 
mailings resulted in additional operational and waste disposal costs 
for USPS and additional postage fees for the Census Bureau, the Census 
Bureau wants to emphasize that many of these costs were both 
anticipated and unavoidable. Indeed, USPS and the Census Bureau agreed 
in a Memorandum of Understanding to allow USPS to save funds by 
destroying the advance letters and reminder postcards for all UAA 
mailings instead of transporting them hack to the Census Bureau as 
part of the First Class service already paid for by the Census
Bureau. The Census Bureau negotiated these terms as part of an effort 
to reduce costs USPS would incur if it followed its normal procedures. 
Undeliverable questionnaires were returned to the Census Bureau for 
disposal, ensuring there was no additional disposal cost to USPS for 
undeliverable questionnaires. The additional postage fees incurred by 
the Census Bureau are essential in supporting our mission of counting 
everyone in the Nation. Mailing replacement questionnaires to those 
households that did not return an initial questionnaire is part of 
that same mission to ensure a complete count. 

*Page 12, Recommendation 2: "...analyzing the reasons why there were 
more undeliverable as addressed mailings than expected, and developing 
strategies and procedures to reduce them." 

Census Bureau response: Because the Census Bureau has already analyzed 
the available reasons for why mailings were undeliverable and because 
the number of unique addresses that were undeliverable did not vary 
substantially from Census Bureau projections (as described above), the 
Census Bureau does not agree with this recommendation for the reasons 
stated above.

and was a second census form that was sent to addresses on the 
Bureau's Master Address File in an effort to increase mail response 
rates. 

[7] The American Community Survey collects demographic, social, 
economic, and housing data. Prior to June 2011, the survey was sent to 
250,000 households a month. Since then, the sample size has been 
increased to approximately 295,000 households each month. 

[8] 13 U.S.C. § 9 prohibits the Bureau from disclosing data it 
collects about individuals and establishments in a manner that would 
identify those individuals and businesses. Similarly, 39 U.S.C. § 412 
prohibits USPS from disclosing names or addresses (past or present) of 
postal patrons or other persons. However, the Census Address List 
Improvement Act of 1994 authorized USPS to share its address 
information with the Bureau. 

[9] In the 2010 Census the Bureau conducted full address canvassing, 
where census workers generally went door-to-door and attempted to 
verify every address in the country. Targeted address canvassing would 
limit this operation to areas in which the Bureau believes more work 
is needed to develop an accurate and complete address list. 

[10] USPS officials stated that they have no way of predicting with 
any certainty the make-up of USPS's workforce in 2020. 

[11] Of the 2,400 USPS employees, the Bureau did not identify how many 
were mail carriers. The Bureau hired almost 10,000 retired federal 
employees, but did not track how many of them were former USPS 
employees.
