Highlights of GAO-10-452T, a testimony before the Subcommittee on 
Information Policy, Census, and National Archives, Committee on 
Oversight and Government Reform, House of Representatives. 

Why GAO Did This Study: 

The U.S. Census Bureau (Bureau) is tasked with conducting an accurate 
count of people living in dwellings known as group quarters as part of 
the 2010 Census. Group quarters consist of college dormitories, 
prisons, nursing homes, and other facilities typically owned or 
managed by an entity providing housing, services, or both for the 
residents. During the 2000 Census, for a variety of reasons, group 
quarters were sometimes counted more than once, missed, or included in 
the wrong location. 

As requested, this testimony will focus on (1) the extent to which the 
Bureau has strengthened its procedures for counting group quarters 
compared to the 2000 Census, and (2) particular challenges and 
opportunities for an accurate group quarters count in Brooklyn. The 
testimony is based on previously issued and ongoing GAO work in New 
York and elsewhere. 

What GAO Found: 

The Bureau developed and tested new procedures to address the 
difficulties it had in identifying and counting group quarters during 
the 2000 Census. For example, the Bureau moved from manual to GPS-
generated map spots, which should reduce the chance of human error and 
of group quarters populations being counted in the wrong jurisdiction; 
moved from a telephone interview to a field verification approach, 
which should increase accuracy; and combined the conventional housing 
unit and group quarters address lists into a single address list, 
which should reduce the chance of double counting. 

Moreover, the Bureau implemented a three-pronged approach to locate 
and count group quarters. The approach consisted of Group Quarters 
Validation, where temporary census workers visited each group quarter 
and interviewed its manager or administrator to determine whether the 
dwelling was a group quarters or some other type of residence. If the 
dwelling was in fact a group quarters, it was then determined what 
category it fit under, and its correct geographic location was 
confirmed. This was followed by the Group Quarters Advance Visit, 
which is currently under way. Census workers are to verify the 
location of the group quarters; identify contact officials; and 
schedule the date, time and other information to help conduct the 
actual enumeration. The actual count of group quarters residents is 
conducted during the third phase of the approach, Group Quarter 
Enumeration from the end of March to mid-May. The effort includes an 
operation known as Service-Based Enumeration, during which people 
commonly referred to as homeless are counted. Additional procedures to 
ensure a complete count of group quarters include a series of quality 
assurance procedures, such as supervisory review of workers’ 
assignments. 

Brooklyn presents challenges as well as opportunities. For example, a 
planning database the Bureau developed to help it target its resources 
placed Brooklyn on a list of top 50 U.S. counties with the highest 
number of people living in hard-to-count areas, based on data from the 
2000 Census. Factors that contribute to the hard-to-count designation 
include poverty levels, high levels of non-English speakers, complex 
household arrangements, as well as a high percentage of rental and 
vacant units, multi-unit buildings, and crowded housing. 

In light of these demographic and housing challenges, a successful 
group quarters count will, at a minimum, depend on how well the Bureau 
executes the following activities: (1) complete remaining group 
quarters activities on schedule, (2) implement the group quarters 
quality assurance procedures as planned, and (3) closely monitor key 
performance metrics to ensure that the group quarters count proceeds 
on track and quickly address any glitches. It will also be important 
for the Bureau to ensure that census workers have knowledge of 
neighborhood culture and living arrangements, and possess the language 
skills to reach out to residents with limited English proficiency. 

What GAO Recommends: 

GAO is not making new recommendations in this testimony, but a past 
report recommended that the Bureau revisit its group quarter 
procedures to ensure that this population was properly located and 
counted. The Bureau implemented this recommendation and strengthened 
aspects of its group quarters procedures. In commenting on a draft of 
this testimony, the Bureau provided some minor clarifying points.

Mr. Chairman and Members of the Subcommittee: 

I am pleased to be here today at the Brooklyn Borough Hall to discuss 
the U.S. Census Bureau's (Bureau) efforts to conduct an accurate count 
of people living in dwellings known as group quarters as part of the 
2010 Census. Group quarters consist of college dormitories, prisons, 
nursing homes, and other facilities typically owned or managed by an 
entity providing housing, services, or both for the residents. During 
the 2000 Census, for a variety of reasons, group quarters were 
sometimes counted more than once, missed, or included in the wrong 
location. 

While a few miscounted households might not seem particularly 
problematic, especially in a nation of more than 300 million people, 
an accurate enumeration is in fact critical. Data from the census--a 
constitutionally mandated effort--are used to apportion seats in the 
Congress, redraw congressional districts, help allocate more than $400 
billion in federal aid to state and local governments, and redraw 
local political boundaries. Census data are also used for planning 
purposes by the public and private sectors. Thus, for Brooklyn, as 
with all localities, an incomplete count could have implications for 
political representation and getting its fair share of federal 
assistance. 

Because of Brooklyn's demographic diversity and other socioeconomic 
factors, the Bureau has identified a number of sections of Brooklyn as 
particularly hard to count. Brooklyn's range of group quarters-- 
including colleges, hospitals, convents, and correctional facilities-- 
only add to the Bureau's enumeration challenges within the borough. 

As requested, my remarks today will focus on (1) the extent to which 
the Bureau has strengthened its procedures for counting group quarters 
compared to the 2000 Census and (2) particular challenges and 
opportunities for an accurate group quarters count in Brooklyn. 

My testimony today is based on our completed and ongoing reviews of 
the Bureau's efforts to build an accurate address list, including 
address canvassing, where temporary census employees go door-to-door 
verifying addresses, and an initial group quarters operation called 
Group Quarters Validation, where the Bureau determines whether an 
address is either a group quarters or conventional housing 
unit.[Footnote 1] For both reviews, we analyzed key documents, 
including plans, procedures, and guidance for the selected activities, 
and interviewed cognizant Bureau officials at headquarters and local 
census offices. In addition, for address canvassing, we made on-site 
observations at 38 locations across the country, including Brooklyn, 
the Bronx, Manhattan, and Queens. Moreover, to examine the Bureau's 
group quarters activities, we observed the Group Quarters Validation 
operations at Atlanta, Georgia; Fresno, Los Angeles, and San 
Bernardino, California; Philadelphia, Pennsylvania; and Washington, 
D.C. We selected these locations because of their geographic 
diversity, variety of group quarters, and hard-to-count populations. 
We also interviewed officials from the New York City Mayor's Office 
and the New York City Department of City Planning to obtain their 
perspectives on the factors that might affect an accurate count in New 
York City. 

On February 16, 2010, we provided the Bureau with a statement of facts 
for our audit work, and on February 17, 2010, the Bureau provided 
written comments. The Bureau made some minor clarifying points, where 
appropriate, we made those changes. We conducted our work 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 objectives. We believe 
that the evidence obtained provides a reasonable basis for our 
findings and conclusions based on our audit objectives. 

In summary, the operational changes the Bureau has made since the 2000 
Census position it to more accurately classify and identify group 
quarters in the correct geographic location for the 2010 Census. An 
accurate group quarters count, particularly in an area as diverse as 
Brooklyn, is a particularly challenging task. Moving forward, it will 
be important for the Bureau to complete remaining group quarters 
operations on schedule. Because of tight deadlines, as the enumeration 
progresses, the tolerance for any operational delays or changes 
becomes increasingly small. Further, the Bureau needs to implement its 
group quarters quality assurance procedures as planned, closely 
monitor key performance metrics to ensure that the group quarters 
count proceeds on track and quickly address any glitches, as well as 
ensure that census workers have knowledge of neighborhood culture and 
living arrangements, and possess the language skills to reach out to 
residents with limited English proficiency. 

Importantly, the Bureau cannot conduct a successful enumeration on its 
own. Indeed, the decennial census is a shared national undertaking, 
and with census forms about to be mailed to millions of households 
across the country, it will soon be up to the public to fulfill its 
civic responsibility to return the questionnaires in a timely fashion. 
According to the Bureau, each percentage point increase in the mail 
response rate saves taxpayers around $85 million and yields more 
accurate data compared to information collected by enumerators from 
nonrespondents. The bottom line, Mr. Chairman, is that Census Day, 
April 1, 2010, is right around the corner. A few weeks from now, the 
success of the 2010 Census will be, both literally and figuratively, 
in the hands of Brooklynites and the nation's residents across the 
country. 

Background: 

A complete and accurate address list, along with precise maps, form 
the foundation of a successful census. An accurate address list is 
critical because, among other reasons, it identifies households that 
are to receive a census questionnaire. Precise maps are critical for 
counting the population in their proper locations--the basis of 
congressional apportionment and redistricting. The Bureau's database 
of the nation's approximately 134 million addresses is called the 
Master Address File. It consists of two types of dwellings: housing 
units such as single-family homes, apartments, and mobile homes, and 
what the Bureau refers to as group quarters. According to Bureau data 
nationwide, more than 7.7 million people, or approximately 3 percent 
of the population, lived in group quarter facilities during the 2000 
Census. Of Brooklyn's population of approximately 2.5 million 
residents at that time, around 39,300 (1.6 percent) lived in group 
quarters. 

In concept, it would appear that an accurate enumeration of group 
quarters residents would be a relatively straightforward task--after 
all, dormitories, nursing homes, and prisons tend to be obvious, have 
fixed addresses, and do not move. Nevertheless, for a variety of 
reasons, counting the group quarters population can be difficult. 

For example, group quarters are sometimes hard to distinguish from 
conventional housing units (see fig. 1), or the address of an 
administrative building might be in a separate geographic location 
than where the residents actually live, as was sometimes the case with 
prison complexes. In prior work, we found that the population count of 
Cameron, Missouri, was off by nearly 1,500 people because the 
population of the state's Crossroads Correctional Center was 
inadvertently omitted from the town's headcount.[Footnote 2] 
Similarly, North Carolina's population count was reduced by 2,828 
people, largely because the Bureau had to delete duplicate data on 
almost 2,700 students in 26 dormitories (see fig. 2) at the University 
of North Carolina at Chapel Hill (UNC).[Footnote 3] Precision is 
critical because, in some cases, small differences in population 
totals could potentially impact apportionment, redistricting 
decisions, or both.

Operational Changes Made for 2010 Position the Bureau to More 
Accurately Classify and Identify Group Quarters: 

The Bureau developed and tested new procedures to address the 
difficulties it had in identifying and counting this population during 
the 2000 Census. For example, the Bureau moved from manual to GPS- 
generated map spots, which should reduce the chance of human error and 
of group quarters populations being counted in the wrong jurisdiction; 
moved from a telephone interview to a field verification approach, 
which should increase accuracy; and combined the housing unit and 
group quarters address lists into a single address list, which should 
reduce the chance of double counting. In addition, following a test of 
certain census-taking procedures in 2004 that was conducted in Queens, 
New York, among other locations, we recommended that the Bureau 
revisit group quarters procedures to ensure that this population was 
properly located and counted.[Footnote 4] The Bureau implemented our 
recommendation and revised its group quarters procedures to clearly 
instruct census workers to properly correct and delete addresses. 
Further, to better ensure a more accurate group quarters count, the 
Bureau employed a three-pronged effort consisting of those operations 
shown in table 1. 

Table 1: Group Quarters Validation is the First Operation in a Three- 
Pronged Effort to Accurately Enumerate Group Quarters: 

Operation name: Group Quarters Validation; 
Dates: 9/28/09 to 10/23/09; 
Purpose: 
* Determine the status of the address as either a group 
quarters, housing unit, transitory location, nonresidential, 
nonexistent, duplicate, or vacant; 
* Determine the type of facility (i.e., correctional facility, health 
care facility, military quarters, dormitory, etc.) and confirm group 
quarters' geographic location; 
* Verify the name, address, contact name and phone number for group 
quarters. 

Operation name: Group Quarters Advance Visit; 
Dates: 2/1/10 to 3/19/10; 
Purpose: Confirm locations of group quarters and identify contact 
officials to facilitate actual enumeration. 

Operation name: Group Quarters Enumeration; 
Dates: 3/30/10 to 5/14/10; 
Purpose: Visit each group quarters to obtain a complete list of the 
names of the people living or staying at the group quarters and 
enumerate all people living or staying there.

[End of table] 

The Bureau's three-pronged approach had temporary census workers visit 
each group quarters and interview its manager or administrator using a 
short questionnaire during Group Quarters Validation. As stated above, 
the goal was to determine whether the dwelling was a group quarters or 
some other type of residence. If the dwelling was in fact a group 
quarters, it was then determined what category it fit under (e.g., 
boarding school, correctional facility, health care facility, military 
quarters, residence hall or dormitory, etc.), and its correct 
geographic location was confirmed. Accurate classification of group 
quarters is important to ensure that the correct enumeration 
methodology is used and the data are tabulated correctly. 

This is followed by the Group Quarters Advance Visit operation, which 
is currently underway. During the advance visit, census workers verify 
the location of the group quarters and identify contact officials, 
schedule the date and time of the actual enumeration, and collect 
other information to help conduct the actual enumeration. 

The actual count of group quarters residents is conducted during Group 
Quarter Enumeration. The effort includes an operation known as Service-
Based Enumeration, during which people commonly referred to as 
homeless are counted.[Footnote 5] While this count is always 
important, the large number of home foreclosures the nation has 
experienced adds to the operation's significance in 2010. Military 
bases and military/maritime vessels are also enumerated as part of 
group quarters. 

For the 2010 group quarters operations, the Bureau drew from a number 
of sources to build its list of potential group quarters addresses 
including data from the 2000 Census, address submissions provided by 
state and local governments, Internet-based research, and group 
quarters located during door-to-door address canvassing. During the 
first of the three group quarters operations (Group Quarters 
Validation), approximately 25,000 temporary workers identified over 
240,000 group quarters facilities from a workload of over 2 million 
potential group quarters in both the United States and Puerto Rico. 
The remaining approximately 1.76 million addresses were identified 
during Group Quarters Validation as conventional housing units, 
transitory locations, nonresidential, nonexistent, or duplicates. All 
addresses that were verified as housing units or transitory locations 
were added to the appropriate address extracts for subsequent 
enumeration operations. In addition, over 7,000 addresses from the 
Group Quarters Validation workload could not be properly processed in 
the Bureau's database because they were returned with insufficient 
information. However, a contingency plan was implemented to ensure 
that these locations were included in the census. 

To further ensure an accurate group quarters count, the Bureau employs 
a number of quality assurance procedures. For example, key quality 
assurance procedures for the completed Group Quarters Validation 
operation included field observations of workers' performance by 
supervisors known as crew leaders. Crew leaders also reviewed workers' 
completed assignments each day, while Quality Control Clerks conducted 
additional reviews. Similar quality assurance procedures are planned 
for the actual enumeration of group quarters. 

The changes made to group quarters operations appear promising, and 
the Bureau plans to evaluate coverage of the group quarters 
population. However, the Bureau will not individually evaluate each of 
the three group quarters operations' effectiveness, cost, or value 
added. Such evaluations could be useful in improving the operations, 
identifying possibly duplicative operations, and identifying potential 
cost savings for 2020. For example, given the large number of nongroup 
quarters included in the workload for Group Quarters Validation (about 
88 percent), the Bureau may want to consider ways to begin the 
operation with a more concise initial workload. Additionally, in both 
Group Quarters Validation and Group Quarters Advance Visit operations, 
census workers personally visit group quarters, verify the facility 
contact information, provide confidentiality information, and collect 
occupancy numbers. Because these activities appear to be duplicative, 
the Bureau may want to reexamine the need to conduct both operations. 

Challenges and Opportunities for Counting Group Quarters Residents in 
Brooklyn: 

Nationally, the enumeration of group quarters is a difficult task for 
the Bureau, and Brooklyn presents its own challenges as well as 
opportunities. For example, a planning database the Bureau developed 
to help it target its resources placed Brooklyn third on a list of top 
50 U.S. counties with the highest number of people living in hard-to-
count areas, based on data from the 2000 Census. Specifically, around 
two-thirds of Brooklyn's (Kings County) total population of 2.5 
million people were found to be living in hard-to-count areas. 
Demographic factors that contribute to the hard-to-count designations 
include poverty levels, low educational attainment, unemployment, and 
complex household arrangements, as well as housing indicators such as 
a high percentage of renters and vacant units, multi-unit buildings, 
and crowded housing. 

Moreover, according to the 2000 Census, 37.8 percent of the borough's 
approximately 2.5 million residents were foreign born and about 46.7 
percent spoke a language other than English at home. Overcoming 
language barriers and other obstacles that have historically come with 
enumerating ethnically diverse populations will be important for the 
Bureau. 

Recognizing that New York City would present challenges for the 2010 
Census, the Bureau selected Queens, New York, as one of two sites to 
test its Group Quarters Validation operation in 2004. The test was 
designed, among other things, to address the difficulties the Bureau 
had in trying to identify and count this population during the 2000 
Census, and to refine its definitions of the various types of group 
quarters to make it easier to accurately categorize them. The Bureau 
determined that the test was a success based on follow-up interviews. 
Out of the 38 follow-up addresses in Queens, 34 were classified 
correctly (89.5 percent). 

Nevertheless, the counting of group quarters is still a challenging 
task. In addition to some of the demographic challenges noted above, 
our observations of the Group Quarters Validation operation 
highlighted other potential trouble spots. For example, we observed 
that while the effort generally proceeded as planned, some temporary 
census workers were concerned that working with paper maps and time 
cards was time consuming and inefficient, and some had difficulties 
identifying a manager or administrator from whom to obtain necessary 
information about the facility. Importantly, our observations were 
limited and we do not know how pervasive these and other issues might 
have been, if at all. 

More recently, a senior New York City official told us about some of 
the local challenges in counting group quarters, including complex 
housing arrangements. He noted that the city has buildings with a 
large number of apartments, where part of the building consists of 
conventional housing units and the other part is group quarters. Such 
situations occur, for example, in housing people with special needs or 
buildings with assisted-living occupants. When this occurred, during 
door-to-door address canvassing, the temporary census workers removed 
the building from the list of conventional housing units and added it 
to dwellings to be visited during the Group Quarters Validation 
operation. 

In addition to these mixed-use building situations, the New York City 
official told us that in cases where buildings have a large number of 
occupants and have been subdivided into various configurations, it can 
be very difficult to determine whether the building is a housing unit 
or group quarters dwelling. While this is an issue for all of New York 
City, it is particularly problematic in Queens and Brooklyn. The 
official told us that with some buildings, it is extremely difficult 
to draw a line as to where the occupation of apartments in a building 
by an extended family ends and a group home situation begins. This is 
especially true where language barriers and fear of government may be 
commonplace. 

In hiring census workers, the Bureau attempts to employ people 
familiar with local living conditions and who possess the language 
skills needed for particular communities. Further, the Bureau has 
translated questionnaires into 5 different languages and has language 
assistance guides available in 59 different languages to help people 
complete their questionnaires. Other tools to help those with limited 
English proficiency, such as telephone questionnaire assistance, are 
available as well. 

In light of these demographic and housing challenges, a successful 
group quarters count will, at a minimum, depend on how well the Bureau 
executes the following activities: 

* Complete remaining group quarters activities on schedule. Indeed, 
the entire census is run on an extremely tight timeline, and as the 
enumeration proceeds, there is little room for operational delays. 

* Implement the group quarters quality assurance procedures as 
planned, and closely monitor key performance metrics to ensure that 
the group quarters count proceeds on track and quickly address any 
glitches. 

* Ensure that census workers have knowledge of neighborhood culture 
and living arrangements and possess the language skills to reach out 
to residents with limited English proficiency. 

Concluding Observations: 

Mr. Chairman, with little more than a month remaining until Census 
Day, the Bureau's efforts to enumerate group quarters generally appear 
to be on track and more robust compared to similar efforts for the 
2000 Census, better positioning the Bureau for a complete and accurate 
headcount. In the coming weeks and months ahead, we will continue to 
monitor the Bureau's progress in counting group quarters, as well as 
the implementation of the census as a whole, on behalf of the 
Subcommittee. 

Mr. Chairman and members of this Subcommittee, this concludes my 
statement. I would be happy to respond to any questions that you might 
have at this time.
