The Honorable William Lacy Clay, Jr.: 
House of Representatives: 

The Honorable Carolyn B. Maloney: 
House of Representatives: 

To assess the quality of the population data collected in the 2000 
Census, the U.S. Census Bureau conducted the Accuracy and Coverage 
Evaluation (A.C.E.) program, which focused on a survey of housing units 
designed to estimate the number of people missed, counted more than 
once, or otherwise improperly counted in the census. As agreed with 
your offices, this report responds to your joint request to review 
A.C.E. life cycle costs. Total life cycle costs for the 2000 Census 
cover a 13-year period from fiscal year 1991 through fiscal year 
2003[Footnote 1] at an estimated cost of $6.5 billion, adjusted to 2000-
year dollars. The A.C.E. program was first included in bureau program 
documents in November 1998 and funded for fiscal years 2000 through 
2003. A predecessor program, Integrated Coverage Measurement (ICM), 
began in May 1995 and was funded by the bureau for fiscal years 1996 
through 1999. We considered both programs to be within the scope of 
your request.

As agreed with your offices, we focused our review on the following 
seven questions concerning ICM/A.C.E. program life cycle costs. 

1. What were the original estimated life cycle costs for the ICM/A.C.E. 
programs?

2. What was the source and support for $400 million in life cycle costs 
reported by the bureau for the ICM/A.C.E. programs? 

3. How were ICM/A.C.E. program costs estimated? 

4. How much did the bureau budget[Footnote 2] for the ICM/A.C.E. 
programs? 

5. What were the obligated life cycle costs for the ICM/A.C.E. 
programs? 

6. Were any budgeted funds for the ICM/A.C.E. programs not used as of 
the end of fiscal year 2001, and if so, how much? 

7. What were the ICM/A.C.E. program-related costs for the bureau dress 
rehearsal in fiscal year 1998?

This report is part of a series of GAO studies on the lessons learned 
from the 2000 Census that can help in the planning and development 
effort now occurring for the 2010 Census.

Results in Brief: 

Although the U.S. Census Bureau tracked some costs of conducting the 
ICM/A.C.E. programs, it did not identify the complete life cycle costs 
of the programs due to three factors. First, program costs prior to 
fiscal year 1996 were not identified because the bureau considered 
costs from earlier years to be part of its general research and 
development efforts and the bureau did not assign unique project codes 
to identify ICM/A.C.E. program and related costs in its financial 
management system. Second, although $3.6 million of fiscal year 1996 
obligated costs were identified in the bureau’s financial management 
system as an ICM special test, the bureau did not consider these costs 
as part of the ICM/A.C.E. programs and it also classified these costs 
as general research. We disagreed with the bureau on this point and 
have included this amount in our report as part of the ICM/A.C.E. life 
cycle costs we could identify. Finally, we were unable to identify 
ICM/A.C.E. portions of costs, such as evaluations and data processing, 
which the bureau included in other 2000 Census programs. Based on 
available information for the seven questions, we found the following:

* The original estimated cycle costs of conducting the ICM/A.C.E. 
programs were about $400 million.

* The first evidence for the original $400 million estimate is in the 
original budget justifications for fiscal year 2000. 

* The bureau based its estimates of ICM/A.C.E. costs on assumptions 
about the needs for personnel and benefits, contractual services, 
travel, office space, equipment, and other costs necessary to conduct 
and support operations of the programs. 

* The budgeted amounts that we identified from bureau records for 
conducting the ICM/A.C.E. programs are about $277 million through 
fiscal year 2003.

* The obligated costs that we identified from bureau records for 
conducting the ICM/A.C.E. programs are about $207 million through 
fiscal year 2001. 

* About $58 million of budgeted funds for the ICM/A.C.E. programs that 
we identified from bureau records were not obligated through fiscal 
year 2001.

* The ICM/A.C.E. program-related costs that we identified from bureau 
records for the 1998 dress rehearsal were about $11 million budgeted 
and about $9 million obligated. 

Due to limitations in the bureau’s available financial data, our 
responses to the seven specific questions identified in your request do 
not include all ICM/A.C.E. program life cycle costs and are limited to 
cost information covering fiscal years 1996 through 2003, except where 
indicated. 

The Department of Commerce expressed disagreement with how we had 
presented answers to the seven questions, but did not comment on the 
substance of our answers. Regarding its concern that our report implied 
managerial or reporting weaknesses, our answers were not prepared with 
the intent of drawing conclusions beyond the information presented. We 
have addressed the comments in the “Agency Comments and Our Evaluation” 
section of this report and the full text of the comments and our 
detailed evaluation is presented in appendix II. 

Background: 

Early in the 2000 Census cycle, the U.S. Census Bureau was researching 
coverage measurement options for the 2000 Census, including the Post 
Enumeration Survey (PES) methods used in past decennial censuses. The 
bureau explored a number of design options aimed at improving data 
accuracy while controlling costs. In 1993, the bureau was also 
evaluating the feasibility of conducting a one-number census, which 
combines the features of both the traditional head count and 
statistical methods to produce a single count before the mandated 
deadlines.In May 1995, the bureau announced that it would conduct a 
sample survey of 750,000 housing units, called Integrated Coverage 
Measurement (ICM), to estimate how many housing units and people it 
would miss or count more than once in the 2000 Census.[Footnote 3] In 
this initial design for the 2000 Census, the bureau planned to use 
statistical methods to integrate the results of this survey with the 
traditional census enumeration to provide a one-number census by 
December 31, 2000. The U.S. Supreme Court ruled in January 1999 that 13 
U.S.C. 195 prohibited the use of statistical sampling to generate 
population data for reapportioning the U.S. House of 
Representatives.[Footnote 4] However, the court’s ruling did not 
prohibit the use of statistical sampling for other purposes, such as 
adjusting formulas to distribute billions of dollars of federal funding 
to state and local governments. 

Following the Supreme Court ruling, the bureau abandoned certain 
statistical aspects of the ICM program, and announced the A.C.E. 
program to assess the quality of the population data collected in the 
2000 Census, using a smaller sample of 300,000 housing units.[Footnote 
5] The bureau conducted A.C.E., which corresponded to the PES in past 
censuses and the ICM in the original 2000 Census Plan, to measure and 
correct the overall and differential coverage of the U.S. resident 
population in the 2000 Census. Although A.C.E. was generally 
implemented as planned, the bureau found that A.C.E. overstated the 
census net undercount. This was due, in part, to errors introduced 
during matching operations and from other remaining uncertainties. The 
bureau has reported that additional review and analysis would be 
necessary before any potential uses of A.C.E. data could be 
considered.[Footnote 6] 

Due to uncertainties or errors in the A.C.E. survey results, the acting 
director of the bureau decided in separate decisions in March 2001 and 
October 2001 that the 2000 Census tabulations would not be adjusted for 
any purpose, including distribution of billions of dollars in federal 
funding. These decisions were consistent with those for the 1990 
Census, which was not adjusted due to other problems. According to 
senior bureau officials, the bureau is continuing to evaluate issues 
related to A.C.E. and the census, and the results of its evaluation are 
expected to influence the bureau’s planning for the 2010 Census.

Bureau Appropriations and Accounting: 

The bureau receives two appropriations from the Congress: (1) salaries 
and expenses and (2) periodic censuses and programs. The salaries and 
expenses appropriation provides 1-year funding for a broad range of 
economic, demographic, and social statistical programs. The periodic 
censuses and programs appropriation includes primarily no-year 
funding[Footnote 7] to plan, conduct, and analyze the decennial 
censuses every decade and for other authorized periodic activities. 
Since fiscal year 1996, the bureau has prepared its annual budget 
request for the 2000 Census in eight broad frameworks of effort that 
were submitted to the Office of Management and Budget (OMB) and the 
Congress. For management, program, financial, staffing, and performance 
purposes, frameworks are further divided by the bureau into activities 
and then projects within these activities.[Footnote 8] 

The bureau accounts for the costs of conducting the ICM/A.C.E. programs 
in its Commerce Administrative Management System (CAMS), which became 
operational in fiscal year 1997. Bureau financial management reports 
generated by CAMS have provided appropriated amounts, expended and 
obligated amounts, and variances to a project level from fiscal year 
1997 to the current period. The ICM/A.C.E. programs are an activity 
comprised of eight projects contained within three frameworks. Fiscal 
year 1996 was the first year the bureau set up a specific project code 
to identify ICM program costs through fiscal year 1999. However, it was 
difficult to identify the change to the A.C.E. program beginning in 
fiscal year 2000 because the bureau did not change many of the project 
descriptions in CAMS from the ICM program. As discussed in our December 
2001 report, we identified specific control weaknesses for fiscal year 
2000 related to the lack of controls over financial reporting and 
financial management systems.[Footnote 9] 

Scope and Methodology: 

To meet the objective of responding to seven questions concerning 
ICM/A.C.E. program life cycle costs, we reviewed and analyzed budget 
and program data for all coverage measurement programs that existed 
during the 2000 Census (for fiscal years 1991 to 2003), which included 
the ICM and A.C.E. programs. We did not audit budget and other 
financial data provided by the bureau. We also reviewed planning and 
methodology documents and other available information in order to 
determine the history of the programs. Also, we identified ICM and 
A.C.E. project accounts and analyzed amounts by fiscal year using the 
financial management reports generated by CAMS. We discussed the 
results of our analysis with senior bureau officials and interviewed 
bureau officials to obtain their views and observations regarding the 
ICM and A.C.E. programs. It was not our objective to assess the 
efficiency of expenditures and obligations against planned budget 
appropriations. 

We encountered several limitations in the scope of our work on this 
assignment as follows.

* We were unable to determine the complete life cycle costs of the 
ICM/A.C.E. programs because the bureau considered any ICM/A.C.E.related 
costs from fiscal years 1991 through 1995 as part of its general 
research and development programs and thus did not separately track 
these costs. Although some costs were tracked in fiscal year 1996, the 
bureau still considered these costs as research and development and did 
not include these costs as ICM/A.C.E. program costs. 

* We were further unable to identify ICM/A.C.E. portions of costs, such 
as evaluations and data processing, which the bureau included with 
other 2000 Census programs.

Our work was performed in Washington, D.C. and at U.S. Census Bureau 
headquarters in Suitland, Maryland, from February 2002 through July 
2002. Our work was done in accordance with U.S. generally accepted 
government auditing standards. On November 17, 2002, the Department of 
Commerce provided written comments on a draft of this report and we 
have reprinted the comments in appendix II. Technical comments were 
also provided by the department and incorporated into the report where 
appropriate, but have not been reprinted. 

Life Cycle Costs: 

Although the bureau tracked some costs of conducting the ICM/A.C.E. 
programs, we found that the bureau did not identify the complete life 
cycle costs of the programs due to the following three factors. 

First, the bureau only tracked the costs of conducting the ICM/A.C.E. 
programs, which covers the period from fiscal year 1997 through 2003. 
Although life cycle costs for the 2000 Census cover a 13-year period 
from fiscal years 1991 through 2003, senior bureau officials said that 
the ICM/A.C.E. program was not viable for implementation until fiscal 
year 1997. Therefore, the bureau considered costs from earlier years as 
part of its general research and development programs and the bureau 
did not assign unique project codes to identify ICM/A.C.E. programs and 
related costs in its financial management system. 

Second, although $3.6 million of fiscal year 1996 obligated costs were 
identifiable in the bureau’s financial management system as an ICM 
special test, the bureau did not consider these costs as part of the 
ICM/A.C.E. programs. Instead, these costs were considered general 
research and development. However, because the bureau separately 
identified these costs as ICM program costs, we have included the $3.6 
million as part of the ICM/A.C.E. program costs we could identify in 
this report. 

Finally, we were unable to identify the ICM/A.C.E. portions of costs, 
such as evaluations and data processing, which the bureau included with 
other 2000 Census programs. For example, in late fiscal year 2000 and 
after, the bureau did not separate A.C.E. evaluations from its other 
2000 Census evaluations in its financial management system. Bureau 
officials stated that the contracts for evaluations included overall 
2000 Census and A.C.E. evaluations, and did not have a separate code 
identifying A.C.E. costs. Similarly, the bureau did not capture all 
costs for items such as data processing by programs like ICM/A.C.E. 
These type of operations were conducted for the 2000 Census overall, 
were budgeted by framework, were not separated by program in the 
bureau’s financial management system, and were not allocated back to 
individual projects. Therefore, we were unable to identify these types 
of costs for the ICM/A.C.E. programs. 

Seven Issues Related To ICM/A.C.E. Programs: 

Due to the limitations in the bureau’s data, our responses to the seven 
specific questions identified in your request do not include all 
ICM/A.C.E. life cycle costs and are limited to available cost 
information covering fiscal years 1996 through 2003, except where 
indicated, and exclude such costs as A.C.E. evaluations and some data 
processing. The following sections include our responses to the seven 
questions on ICM/A.C.E. program life cycle costs.

1. What were the original estimated life cycle costs for the ICM/A.C.E. 
programs?

The bureau originally estimated the costs of conducting the ICM program 
to be about $400 million when it planned to use statistical methods to 
integrate the results of a survey based on 750,000 housing units with 
the traditional census enumeration to provide a one-number census. This 
original estimate included fiscal years 1997 through 2003. However, 
this estimate was incomplete, as the bureau did not include program 
costs prior to fiscal year 1997 because it considered them as general 
research and development costs. The bureau also combined costs for 
A.C.E. evaluation and data processing with other program costs in 
different frameworks. 

The U.S. Supreme Court ruled in January 1999 that statistical sampling 
could not be used to generate population data for reapportioning the 
House of Representatives. As a result of the ruling, in June 1999, as 
part of its amended fiscal year 2000 budget request, the bureau 
decreased the ICM/A.C.E. program by about $214 million, due to a 
reduction in the sample size from 750,000 to 300,000 housing units. We 
could not identify from bureau records an original estimate for only 
A.C.E. life cycle costs for completing the scaled-back survey.

2. What was the source and support for $400 million in life cycle costs 
reported by the bureau for the ICM/A.C.E. programs? 

In 1995, the bureau estimated life cycle costs for the 2000 Census in 
13 frameworks; however, bureau documents did not break out the 
frameworks into activities and projects.[Footnote 10] The first 
evidence for the $400 million cost estimate for conducting the 
ICM/A.C.E. program for the 2000 Census was submitted as part of the 
original fiscal year 2000 budget justification for overall census 
operations to the Congress in February 1999. This original budget was 
prepared based on the initial design for ICM, which planned to 
incorporate statistical methods to integrate the results of a survey 
based on 750,000 housing units with the traditional census enumeration 
to provide a one-number census. 

3. How were ICM/A.C.E. program costs estimated? 

According to bureau officials, estimates of ICM/A.C.E. costs are based 
on assumptions about the needs for headquarters and support staff and 
related benefits, contractual services, travel, office space, and 
equipment costs necessary to conduct and support operations of the 
program. The bureau used an electronic cost model to calculate many of 
the estimates for the ICM/A.C.E. programs.

For personnel costs, the A.C.E. program costs were divided into costs 
for data collection and costs for headquarters full-time equivalent 
(FTE) staff and support staff as follows. 

* The A.C.E. field staff needed to conduct each A.C.E. data collection 
operation included enumerators, crew leaders, field operations 
supervisors, and assistants. The cost model was designed to estimate 
the number of field staff positions, hours, FTEs, salary costs, and 
mileage costs. In the cost model, each operation had its own distinct 
production assumptions based on the data collection needs for that 
operation. Based on operational needs, the bureau determined the 
assumptions for production rates, mileage rates, production and 
training days, and hours worked per day. 

* The magnitude of the A.C.E field production labor was determined by 
the A.C.E. field operation workload. Based on the workload, the number 
of A.C.E. enumerators was calculated for each operation. Then, based on 
the number of enumerators, the bureau determined the number of crew 
leaders, field operations supervisors, and assistants needed. The 
number of production positions became the bureau’s basis for the number 
of staff to be trained. The number of positions, both production and 
trainee, was then used to estimate the salary cost as a function of the 
total production and trainee hours and applicable labor rates.

* Once labor rates were determined, a percentage was used to calculate 
benefit costs.

For nonpersonnel costs, the bureau estimated the costs based on the 
following. 

* Contract costs were estimated based upon procurement needs for goods 
and services, including contractors hired to assess the feasibility of 
A.C.E. operations and to evaluate the results of the program. 

* Travel costs were estimated using the numbers of production and 
trainee positions to calculate the average miles per case and the 
mileage reimbursement rate.

* Office space estimates were based on the number of people who needed 
space, the number of square feet per person, and the cost per square 
foot.

* Equipment and supply costs were based on the needs of each employee 
and the specific needs of each A.C.E. operation. This included laptop 
computers that were provided to field data collection staff to conduct 
interviews and to monitor the operational progress of the program. 

4. How much did Census budget for the ICM/A.C.E. programs? 

As shown in figure 1, we identified from bureau records budgeted 
amounts of $276.5 million for conducting the ICM/A.C.E. programs. Of 
this amount, $64.2 million was for the ICM program from fiscal year 
1996 through 1999, and $212.3 million was for the A.C.E. program from 
fiscal year 2000 through 2003. Also, see table 1 in appendix I for 
additional details of ICM/A.C.E. budgeted costs by framework and 
project.

5. What were the obligated life cycle costs for the ICM/A.C.E. 
programs? 

As shown in figure 2, we identified from bureau records obligated 
amounts of $206.9 million, of which $58.4 million was for the ICM 
program from fiscal year 1996 through 1999, and $148.5 million was for 
the A.C.E. program for fiscal years 2000 and 2001. We did not include 
obligated costs for fiscal year 2002 as they are not yet final and 
fiscal year 2003 obligations have yet to be incurred. Also, see table 2 
in appendix I for additional details of obligated costs for the 
ICM/A.C.E. programs.

As shown in figure 3, of the $206.9 million of obligated ICM/A.C.E. 
program costs through fiscal year 2001, 65 percent or about $135 
million were for salaries and benefits. The next largest category was 
for contractual services, which constituted about $22.3 million or 11 
percent of ICM/A.C.E. program costs. The third largest category was for 
equipment, which constituted about $22 million, or 11 percent of 
ICM/A.C.E. program costs. Other costs - including office space, travel, 
and supplies - made up about $27.6 million or 13 percent of program 
costs.

6. Were there any budgeted funds for the ICM/A.C.E. programs not used 
as of the end of fiscal year 2001, and if so, how much? 

About $57.7 million of budgeted funds that we identified from bureau 
records for the ICM/A.C.E. programs were not obligated through fiscal 
year 2001. 

* For fiscal years 1996 and 1997, there were no unused funds for the 
ICM program.

* For fiscal year 1998, about $2.7 million remained unobligated for the 
ICM program because of the following reasons. 

- $1.5 million was due to the dress rehearsal housing unit follow-up 
workload being smaller than anticipated; a bureau bonus 
program[Footnote 11] not being implemented although budgeted; and less 
mileage reimbursement than budgeted under project code 6205 (ICM Dress 
Rehearsal).$400,000 was due to unused budgeted funds for salaries 
related to project code 6352 (ICM Coverage Measurement). 

- $400,000 was due to unused budgeted funds for salaries and a delay in 
awarding contract services under project code 6444 (ICM Procedures and 
Training). 

- $400,000 was due to unused budgeted funds for regional office manager 
and assistant manager salaries and travel costs due to delays in hiring 
under project code 6480 (ICM Collection).[Footnote 12] 

* For fiscal year 1999, about $3.6 million budgeted for the ICM program 
remained unobligated due to the following reasons. 

- About $2.3 million related to project code 6480 (ICM Collection) was 
not used, including $1.6 million due to unspent salaries related to 
hiring delays, hiring fewer staff than authorized for selected 
positions, and hiring qualified candidates at less than budgeted 
levels. Another $0.7 million was due to less mileage reimbursement than 
budgeted.

- About $1.2 million was due to equipment costs and hardware for 2000 
being less than budgeted under project code 6608 (ICM Processing). 

* For fiscal year 2000, about $42.5 million remained unobligated for 
the A.C.E. program, consisting of almost $40 million for project code 
6480 (A.C.E. Collection), which was budgeted for the program but was 
not used primarily because of the following reasons. 

- About $32 million was due to unspent salaries and benefits for office 
staff in field offices from hiring fewer positions and hiring at lower 
grades than budgeted and from lower data collection costs due to a 
reduction in cases requiring personal visits. 

- About $4 million was due to the fact that contract obligations for 
laptop computers and support services were less than budgeted. 

- About $2 million resulted from lower GSA rents than budgeted. 

- For fiscal year 2001, about $8.9 million of unobligated funds 
remained for the A.C.E. program, consisting mostly of $6.4 million for 
project code 6480 (A.C.E., Collection), which was budgeted for the 
program but was not used. 

7. What were the ICM/A.C.E. program-related costs for the bureau dress 
rehearsal in fiscal year 1998?

As shown in appendix I, the ICM program-related costs for the 1998 
dress rehearsal were captured under project code 6205 (ICM Dress 
Rehearsal). Of the total $10.8 million budgeted, we were able to 
identify obligations of $9.4 million from bureau records. Most of these 
obligations were incurred in fiscal year 1998, with some follow-up 
amounts in the first quarter of fiscal year 1999. According to bureau 
officials, the dress rehearsal project activities included data 
collection and case management, data processing, and implementation of 
estimation operations. This project also covered the implementation of 
ICM and some elements of A.C.E. at the Sacramento, California, and 
Menominee County, Wisconsin dress rehearsal sites. 

Agency Comments and Our Evaluation: 

The Department of Commerce comments expressed disagreement with how we 
presented answers to the seven questions in the report, but did not 
comment on the substance of our answers. It said that our report’s 
conclusions imply financial management or reporting failures and 
suggest specific control weaknesses in the bureau’s financial 
management systems. It also said we inferred an inability to properly 
manage from large unexplained discrepancies between budgeted and 
obligated amounts for the ICM/A.C.E. programs. Our answers were not 
prepared with the intent of drawing conclusions beyond the information 
presented and we did not make interpretive conclusions or qualitative 
judgments about the ICM/A.C.E. programs. Although not within the scope 
of this report, our December 2001 report identified internal control 
weaknesses for fiscal year 2000 related to the bureau’s lack of 
controls over financial reporting and financial management 
systems.[Footnote 13] 

The department’s written comments and our more detailed evaluation of 
its concerns are presented in appendix II. 

As agreed with your offices, unless you announce its contents earlier, 
we plan no further distribution of this report until 7 days after its 
issuance date. At that time, we will send copies to the Chairman and 
Ranking Minority Member of the Senate Committee on Governmental 
Affairs, the House Committee on Government Reform, and the House 
Subcommittee on Civil Service, Census, and Agency Organization. We will 
also send copies to the Director of the U.S. Census Bureau, the 
Secretary of Commerce, the Director of the Office of Management and 
Budget, the Secretary of the Treasury, and other interested parties.

Comments from the U.S. Department of Commerce: 

U.S. Census Bureau: 

U.S. General Accounting Office draft report entitled 2000 Census: 
Complete Costs of Coverage Evaluation Programs Are Not Available: 

General Comments on the Board: 

The U.S. Census Bureau takes exception with the central conclusions of 
this report, as they imply that large sums of money associated with the 
Integrated Coverage Measurement (ICM) and Accuracy and Coverage 
Evaluation (A.C.E.) Programs for Census 2000 were not properly reported 
as being spent on those programs. Moreover, the General Accounting 
Office (GAO) suggest that the Census Bureau was unable to properly 
estimate full-cycle costs for these programs that this inability, 
coupled with the fact that there was almost $5 million in budgeted but 
unobligated funds for ICM/A.C.E. programs during FY 1998-2001, 
indicates that there were specific control weaknesses in the Census 
Bureau's financial management systems. The GAO's apparent remedy for 
this would be for the Census Bureau to allocate ICM/A.C.E. program 
expenditures to codes established for this program at an earlier point 
in the census cycle. 

(See Comment 1): 

The Census Bureau respectfully disagrees with this position. We believe 
that we have accurately captured the ICM/A.C.E. costs attributable to 
Census 2000 in our financial planning. Prior to 1996, the Census Bureau 
had not sufficiently defined the specific coverage measurement program 
that ultimately became the ICM. Consequently, the Census Bureau did not 
allocate any expenditures to ICM project codes. This is in keeping with 
Census Bureau procedures regarding a wide range of decennial census 
operations. It underscores an important point: namely, that the GAO's 
inability to identify portions of the costs attributable to ICM/A.C.E. 
program is not demonstrative of a financial or reporting failure; it 
simply indicates that the Census Bureau's system and categorization of 
Census 2000 expenditures do not permit the parsing out of the specific 
breakdowns requested. 

(See Comment 2): 

To be sure, the dual system estimation (DSE) methodology cental to the 
ICM/A.C.E. program was under development. In fact, the Census Bureau 
had been developing DSE methodology and other sampling methodologies 
for many years. But it was logical for us to allocate expenditures 
associated with this and other decennial programs to a general research 
and development activity code early in the decade when we were 
developing and testing decennial census operations. Costs for the ICM 
Special Test in 1996, which the GAO specifically addresses, also should 
be understood in the context of the Census Bureau's ongoing development 
of DSE procedures. It was only after Census 2000 operations were 
finalized in 1997 that a specific code was established for the ICM 
program as a component of Census 2000. It is, therefore, misleading for 
the GAO to include the costs for the development of DSE methodologies 
early in the decade in reporting the full-cycle costs for the 
ICM/A.C.E. programs. 

The GAO also cites discrepancies between the $400 million cost estimate 
provided in early 1999 and the budgeted amount totaling roughly $277 
million, both of which were calculated through FY 2003. Following the 
January 1999 Supreme Court riling prohibiting the use of sampling to 
produce the apportionment counts, the Census Bureau revised its plans 
for its coverage measurement program. However, the Census Bureau had 
already prepared its FY 2000 budget request for Census 2000 activities, 
which included a cost estimate of $400 million for the ICM program for 
FY 1997-2003. The Census Bureau's revised plans called for a coverage-
measurement survey-the A.C.E.-of less than half the size of the ICM. 
This major revision to the Census Bureau's coverage measurement program 
explains the large discrepancy between the $400 million cost estimate 
provided in early 1999 and the budgeted accounts for totaling roughly 
$277 million.[Footnote 14] The Census Bureau subsequently revised its 
budget request for Census 2000, based on the requirements for the 
A.C.E. program. 

(See Comment 3): 

In addition, the GAO reports both budgeted and obligated full-cycle 
costs for the ICM/A.C.E. programs. The obligated full-cycle cost total 
of approximately $207 million covers the period FY 1996-2001, given 
that obligation for FY 2002 and FY 2003 are not yet known. The budgeted 
full-cycle cost total of approximately $277 million covers the period 
FY 1996-2003, although the FY 2003 amount has been revised recently. 
The GAO suggested that the difference between these two totals 
demonstrates the Census Bureau's inability to properly manage and 
record expenditures relating to the ICM/A.C.E. programs. Again, we 
disagree with the GAO's interference. First of all, the totals cover 
two different time periods, with budgeted costs of these programs for 
FY 2002 and FY 2003 totaling $12.5 million. Much of the remainder of 
unobligated funds (approximately $58 million) can be attributed to the 
$42.5 million in unobligated funds from FY 200 alone. While the Census 
Bureau had made reductions to its budgeted amounts for the A.C.E. 
Collection based on the smaller sample size of the A.C.E., the conducts 
of the A.C.E. data collection operations in FY 2000. This result is 
consistent with what was achieved for similar Census 2000 field 
operations conducted during FY 2000. 

(See Comment 4): 

Finally, the GAO notes that ICM/A.C.E. portions of costs relating to 
data processing and evaluations are not captured in the full-cycle cost 
calculations. We are not aware of any post-FY 1995 data processing 
costs related to ICM/A.C.E. programs that are not included in the 
project codes that the GAO used to calculate the full-cycle costs. With 
regard to evaluations, the GAO has correctly stated that there is not a 
separate project code for evaluations relating to the ICM/A.C.E. 
programs. It is not possible to parse out the total costs of the 
evaluations relating to these programs, because evaluations of all 
Census 2000 programs and operations were assigned the same project 
code. Once again, the inability to identify the portions of these costs 
attributable to ICM/A.C.E. programs is not demonstrative of a financial 
management or reporting failure, it simply indicates that the Census 
Bureau's system and categorization of Census 2000 expenditures do not 
permit the parsing out of the specific breakdowns requested. If it were 
possible to discern thee costs, based on our experience, we believe 
they would prove to be a relatively small percentage of the full-cycle 
costs of the ICM/A.C.E. program. 

(See Comment 5): 

The following are GAO’s comments on the letter dated October 17, 2002, 
from the Department of Commerce. 

GAO Comments: 

1. Our report does not make interpretive conclusions or qualitative 
judgments about the ICM/A.C.E. programs. With bureau assistance, we 
compiled unaudited budgeted and obligated amounts for projects that the 
bureau reported in its financial management system as being ICM/A.C.E. 
related. Our review of these reported costs indicated that life cycle 
costs of the ICM/A.C.E. programs were not complete due to three factors 
as discussed in the body of our report. One of the factors we cited 
that contributed to incomplete life cycle costs was $3.6 million of 
fiscal year 1996 obligated costs for an ICM special test. In its 
comments, the bureau pointed out that prior to fiscal year 1996 it had 
not defined the coverage measurement program, did not allocate any 
expenditures to the ICM project codes, and could not identify any costs 
prior to fiscal year 1996. Thus, it was the bureau’s decision to not 
track specific costs during this time period and to consider them as 
general research.

We also stated that $57.7 million of budgeted funds were not obligated 
or spent through fiscal year 2001, and, with input from bureau 
officials, we obtained reasons why these funds were not spent. The 
bureau did not take exception to these facts in its response and we 
noted no improprieties in this report.

Regarding a reference to specific control weaknesses in its financial 
management systems, the scope of this report did not include an 
assessment of internal control weaknesses in the bureau’s financial 
management systems. However, in a December 2001 report, we identified 
specific internal control weaknesses for fiscal year 2000 related to 
the bureau’s lack of controls over financial reporting and financial 
management systems.14

2. We still disagree with the bureau on this point, as we stated in the 
draft report. Because these costs were separately tracked by a specific 
ICM project code in the bureau’s financial management system, we 
included them in the costs of the ICM/A.C.E. programs that we could 
identify. 

3. We did not cite discrepancies between the $400 million original cost 
estimate of the ICM/A.C.E. programs provided in early 1999 and the $277 
million budgeted amount we identified for fiscal years 1996 through 
2003. An objective of our report was to determine what were the 
original estimated life cycle costs for the ICM/A.C.E. programs. The 
earliest amount that we could identify from bureau records was $400 
million and in our report we explained that this amount was estimated 
by the bureau before the January 1999 Supreme Court decision. As a 
result of this decision and as disclosed in our report, the bureau 
decreased the ICM/A.C.E. program by about $214 million due to a 
reduction in the sample size from 750,000 to 300,000 housing units. 

4. We did not suggest that the difference between $277 million of 
budgeted life cycle costs and $207 million of obligated life cycle 
costs demonstrated the bureau’s inability to properly manage and record 
expenditures relating to the ICM/A.C.E. programs. As presented in our 
report, the budgeted amount of $277 million included fiscal years 1996 
through 2003 and the obligated amount of $207 million included amounts 
for 2 fewer fiscal years (1996 through 2001). As the bureau pointed out 
in its response, it is too soon to determine obligated amounts for 
fiscal years 2002 and 2003 that were budgeted for $12.5 million. 
Variances for the remaining $57.7 million of unspent funds are 
discussed in comment 1.

5. The bureau agreed that it did not capture the life cycle costs of 
evaluations for the ICM/A.C.E. programs because evaluations for all 
2000 Census programs were charged to one project code. However, the 
bureau believes that data processing costs were included in the life 
cycle costs of the ICM/A.C.E. programs and stated that not being able 
to identify portions of these costs is not demonstrative of a financial 
management or reporting failure. We agree with the bureau that some 
data processing costs were captured in the life cycle costs of the 
ICM/A.C.E. programs as evidenced by project codes for ICM/A.C.E. data 
processing for procedures, training, and processing as part of 
Framework 5. However, we do not believe that all data processing costs 
were included. Similar to evaluation costs, the bureau attributed much 
of its computer hardware and support costs to overall 2000 Census 
programs, and did not allocate costs to specific projects or programs.
