2010 Census
Operational Changes Made for 2010 Position the U.S. Census Bureau to More Accurately Classify and Identify Group Quarters Gao ID: GAO-10-452T February 22, 2010The 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.
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.

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.

[5] Service Based Enumeration is a method of data collection designed
to count people at facilities that primarily serve people without
conventional housing in the United States and Puerto Rico. These
facilities include emergency or transitional shelters, soup kitchens,
and regularly scheduled mobile food van stops. In addition, Service
Based Enumeration counts people at targeted nonsheltered outdoor
locations where people might have been living in March (before Census
Day, April 1) without paying to stay there and who did not usually
receive services at soup kitchens, shelters, or mobile food vans.
