Federal Statistical System: Agencies Can Make Greater Use of Existing Data, but Continued Progress Is Needed on Access and Quality Issues
Released: 2012-03-26T00:00:00


Highlights: section_title: Why GAO Did This Study
paragraphs: As demand for more and better information increases, rising costs and other challenges require that the federal statistical system identify efficiencies. To explore opportunities to improve cost-effectiveness, GAO was asked to (1) review how the Office of Management and Budget (OMB) and agencies improve information collections, (2) evaluate opportunities and constraints for agencies to use administrative data (information collected as part of the administration of a program or held by private companies) with surveys, and (3) assess the benefits and constraints of surveys making greater use of the Census Bureau’s American Community Survey (ACS) data and resources. GAO focused on collections administered to households and individuals, analyzed statutory and agency documents, did five case studies of surveys, reviewed documentation of representative samples of active surveys, and interviewed agency officials and experts.

section_title: What GAO Found
paragraphs: The Office of Management and Budget (OMB), agencies, and interagency statistical committees have distinct roles in identifying opportunities to improve federal information collection efforts. OMB exercises several authorities that promote the system’s efficiency, including overseeing and approving agency information collections. The website Reginfo.gov provides the public with information, such as cost and burden, on collections that OMB reviews, though GAO’s review identified some discrepancies in selected items. OMB periodically issues guidance to agencies on complying with federal requirements for information collections, but this guidance generally does not prescribe specific actions to take. GAO’s analysis of agencies’ documentation of active surveys indicated that 77 percent included detailed descriptions of efforts to identify duplication, while those that did not tended to be for collections that are unlikely to duplicate existing information; and 75 percent reported actions beyond those required by statute to solicit external input. OMB, through enhanced guidance, could promote additional awareness of options agencies can take to identify duplication and solicit input. Interagency committees, which primarily draw members from the 13 agencies that have statistics as their primary focus, are particularly important in helping ensure collaboration. The committees have numerous projects underway aimed at addressing key challenges facing the statistical system. However, mechanisms for disseminating information about their work are not comprehensive or up-to-date. Though member agencies are the most-likely customers of the committees’ products, making information about committee work and priorities more accessible could benefit other agencies, academics, and the general public. It could also benefit committee members by providing a central repository for information.

Administrative data have greater potential to supplement rather than replace survey data. Agencies currently combine the two data sources in four key ways to cost-effectively increase efficiency and quality. Specifically, agencies use administrative data to: (1) link to survey data to create new data products; (2) supplement surveys’ sample frames; (3) compare to survey data to improve accuracy and design of surveys; and (4) combine with survey data to create, or model, estimates. However, expanding the use of administrative data faces key constraints related to the access and quality of the data. While agencies and committees are taking steps to address these constraints and facilitate the process through which agencies work together to share data, individual tools may not be sufficient. A more-comprehensive framework for use by all agencies involved in data-sharing decisions that includes key questions to consider when evaluating potential use of administrative data could make the decision process more consistent and transparent.

ACS, an ongoing monthly survey that provides information about the nation’s communities, offers agencies important opportunities to increase the efficiency and reduce the costs of their surveys, but its current design limits the extent to which agencies can utilize some of these opportunities. Uses that do not affect ACS design or the survey’s respondents, such as using ACS estimates to inform survey design or evaluate other surveys’ results, have widespread potential. However, more-intensive uses, such as adding content or supplemental surveys to the ACS, currently have limited potential.

section_title: What GAO Recommends
paragraphs: GAO recommends that OMB take several actions to improve the broader efficiency of the federal statistical system, including implementing additional quality-control procedures for selected website data, enhancing awareness of ways to meet information collection requirements, better disseminating information on interagency committees, and developing comprehensive guidance for agencies to use when considering data sharing. OMB generally agreed with all of GAO’s recommendations.

section_title: Letter
paragraphs: Information is a critical strategic asset, and all levels of government, as  well as businesses and private citizens, depend on relevant, accurate,  and timely social, demographic, financial, and other federally funded data- collection efforts to inform their planning and other decisions. Collectively,  this information plays a vital role in measuring the health and well-being  of the nation, informing private-sector investment, allocating federal  funding, and measuring the outcomes of government programs.

However, the federal statistical system, including (1) agencies that collect  and analyze data, and (2) the Office of Management and Budget (OMB),  which oversees the system, faces several challenges. Key among them is  that the demand for information is increasing, especially as organizations  look for ways to operate more cost-effectively, while the cost of collecting  data is growing and response rates to surveys—both government and  private-sector—are declining, driven in part by concerns over privacy and  confidentiality. In the face of these challenges, it will be important for  federal statistical agencies to identify opportunities to increase their  efficiency, while maintaining or improving data quality and minimizing  respondent burden and respecting privacy and confidentiality concerns.  Greater use of administrative data, which includes information collected  as part of the execution of government programs as well as information  held by private companies, has been proposed as one approach to  enhance efficiency and quality. Another potential approach is making  greater use of the American Community Survey (ACS), a monthly survey  that replaced the census long form and provides annual data on  communities’ demographic, social, economic, and housing conditions.

At your request, this report (1) reviews the ways in which OMB and  agencies identify opportunities for improvement and increased efficiency;  (2) evaluates opportunities and constraints for the statistical agencies to  use administrative data in conjunction with selected surveys; and (3)  assesses the benefits and constraints of selected surveys making greater  use of ACS data and resources.

To achieve our objectives, we focused our review on statistical  information collections administered to households and individuals, as  opposed to businesses or other entities, and subject to the Paperwork  Reduction Act (PRA), which requires OMB approval of certain federal  data collections. Specifically, we performed case studies of five federal  surveys: the Consumer Expenditure Surveys, sponsored by the Bureau of  Labor Statistics (BLS); the National Health and Nutrition Examination  Survey and the National Health Interview Survey, both sponsored by the  National Center for Health Statistics (NCHS); the National Survey of  College Graduates, sponsored by the National Center for Science and  Engineering Statistics (NCSES), part of the National Science Foundation;  and the Survey of Income and Program Participation, sponsored by the  Census Bureau. We selected these surveys based on several factors,  such as their size and cost and whether they use or have the potential to  use administrative data or ACS data. We focused our selection on large  surveys, in terms of both cost and number of respondents, because  potential cost savings and efficiency gains are likely greatest for them.

For examples of our prior work, see: GAO, Federal Information Collection: A  Reexamination of the Portfolio of Major Federal Household Surveys Is Needed,  GAO-07-62 (Washington, D.C.: Nov. 15, 2006); American Community Survey: Key  Unresolved Issues, GAO-05-82 (Washington, D.C.: Oct. 8, 2004). collections. We analyzed the subject matter of all of the collections in our  scope and, for a representative sample of 106 surveys, analyzed  agencies’ reported efforts to identify duplication and consult with persons  outside of the agency. We interviewed experts on the federal statistical  system and officials at OMB and the four agencies that administer the  case-study surveys to learn about coordination among agencies, efforts  agencies take to identify improvement, and experts’ and officials’  perspectives on current and potential uses of administrative data and  ACS. We also interviewed and discussed these topics with officials at the  Department of Agriculture’s Economic Research Service (ERS), which is  a member of several interagency statistical committees and the lead  agency for the Statistical Community of Practice and Engagement. In  evaluating OMB, agency, and interagency actions to improve efficiency,  we used as criteria the requirements of the PRA and practices identified  in our prior work on agency collaboration.

For the purposes of this review, we assessed the reliability of the data  from the Reginfo.gov website and determined that they were reliable for  some of our purposes but not others. Specifically, we reviewed related  documentation, conducted interviews with OMB officials, and compared  selected data elements from the Reginfo.gov website to supporting  documents. We determined that the data were sufficiently reliable for  purposes of identifying the collections within our scope and obtaining  information on the collections’ subject matter and actions taken by  agencies to identify duplication and solicit input. As described later in this  report, data provided on the website were not sufficiently reliable for the  purpose of assessing collections’ annual cost to the federal government  and annual respondent burden hours. Appendix I includes additional  information on our scope and methodology. Appendix II contains more  detailed descriptions of our case-study surveys.

We conducted this performance audit from December 2010 to February  2012 in accordance with generally accepted government auditing  standards. Those standards require that we plan and perform the audit 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.
subsections: section_title: Background
paragraphs: In contrast to many other countries, the United States does not have a  primary statistical agency. Instead, the statistical system is  decentralized, with statistical agencies generally located in different  government departments. This structure keeps statistical work within  close proximity to the various cabinet-level departments that use the  information. There are 13 federal agencies, referred to as the principal  statistical agencies, which have statistical activities as their core mission.  These agencies conduct much of the government’s statistical work,  though there are more than 80 additional federal agencies that carry out  some statistical work in conjunction with their primary missions. The 13  principal statistical agencies are all attached to a cabinet-level department  or an independent agency that reports to the president. As shown in  figure 1, they are located at different levels within their respective  departments and agencies.

For fiscal year 2011, $6.83 billion was requested for statistical work,  which includes the collections in our scope as well as work that focuses  on entities other than households and individuals, such as businesses  and farms. This amount is about 0.2 percent of that year’s total federal  budget request. Much of this work is concentrated in the 13 principal  statistical agencies, which account for approximately 40 percent of  requested funding. The budget request for the Census Bureau is among  the highest of the principal statistical agencies. Excluding funding related  to the decennial census, the fiscal year 2011 budget request for the  Census Bureau was $558 million. In addition to conducting its own  statistical activities, the Census Bureau also performs statistical work for  other agencies on a reimbursable basis.

Most of the collections in our scope have relatively modest annual costs.  In a sample of 112 information collections that fell within our scope and  were active as of September 22, 2011, the majority cost less than  $500,000 annually, and fewer than one in five cost more than $1 million  annually. There are a few, more expensive, large and broad-based collections such as the Current Population Survey and National Health  Interview Survey, both of which cost tens of millions of dollars each year,  and the ACS, which costs over $200 million annually (see fig. 2).

Various statutes and guidance from OMB and other entities establish  standards for quality and privacy that apply to the federal statistical  system. One of the most significant statutes is the PRA, which designates  OMB as the coordinating body of the federal statistical system. The PRA  establishes requirements that agencies must meet in order to administer  information collections, and OMB must meet in overseeing the system,  including that it issue guidance to agencies. Other entities also provide  guidance to agencies that conduct statistical work. In addition, use of  information must be balanced with protection of privacy and  confidentiality. Statutes such as the Confidential Information Protection  and Statistical Efficiency Act (CIPSEA) apply to the federal statistical  system and focus on ensuring the privacy and confidentiality of  respondents’ information. Agency-specific statutes also protect the  privacy and confidentiality of data collected by those agencies. For  example, Title 13 of the U.S. Code authorizes the Census Bureau to  request and collect information from individuals but also guarantees the  confidentiality of these data and establishes penalties for unlawfully  disclosing this information. Additional statutes are described in more  detail in appendix III.

section_title: OMB and Agencies Take a Number of Steps to Ensure Efficient Information Collections, Though Opportunities Exist for Refinements
subsections: section_title: OMB Uses Its Oversight Authority to Improve Efficiency
paragraphs: Under PRA, OMB, through its Office of Information and Regulatory Affairs  (OIRA), has responsibility and broad authority to improve the efficiency  and effectiveness of federal information resources.is charged with the oversight and coordination of federal agencies’  statistical activities. Specifically, these oversight functions are carried out  by OIRA’s Statistical and Science Policy Branch, headed by the Chief  Statistician, which includes five staff members who work closely on these  oversight and coordination activities with approximately 25 other OIRA  desk officers. OMB exercises four key authorities that contribute to the  efficiency of the federal statistical system:   In this regard, OMB

Oversight and approval of information collections: OMB generally  must approve information collections that are to be administered to 10  or more people. OMB staff review agencies’ information collection requests to determine whether proposed collections meet PRA  standards by assessing such factors as whether they are necessary  for the mission of the agency and do not unnecessarily duplicate  existing information. This review also enables OMB to identify  opportunities for improvement. For example, according to OMB and  agency officials, if it determines that it is necessary to ask similar  questions in multiple collections, then OMB works to ensure that  agencies ask them in a consistent manner, when appropriate.

Standard-setting and guidance to agencies: OMB is responsible  for developing and implementing governmentwide policies, principles,  standards, and guidelines related to statistical issues, such as  procedures and methods for collecting data and disseminating  information. Specifically, OMB issues directives, guidance, and  memorandums, and provides additional information through  information sessions and presentations, to guide federal data  collection and promote the quality and efficiency of information  collections. For example, OMB published “Questions and Answers  When Designing Surveys for Information Collections,” a set of 81  questions and answers on the OMB review process for agency  information collection requests required by PRA.Standards and Guidelines for Statistical Surveys, which outlines 20  standards and related guidelines for the design and methodology of  statistical surveys. Finally, OMB issues memorandums focusing on  various topics, with recent ones clarifying the guidance for complying  with PRA and encouraging agencies to coordinate efforts to share  data.

Budget development and reporting: Although agency budgets are  initiated within agencies, OMB is responsible, under PRA, for ensuring  that agency budget proposals are consistent with systemwide  priorities for maintaining and improving the quality of federal statistics.  In addition to the budgets themselves, OMB reports information to the  public and Congress about the identification of key priorities through  key documents. OMB annually reports on the paperwork burden  federal collections impose on the public in the Information Collection  Budget of the United States Government. In addition, OMB annually  describes statistical program funding and proposed program changes  for statistical activities in the Statistical Programs of the United States  Government.

Other statistical-policy coordination activities: The Chief  Statistician and staff in OMB’s Statistical and Science Policy Branch  participate in both formal and informal coordination activities with  agencies. OMB’s role and participation in the formal interagency  committees are discussed later in this report. In general, it maintains  regular contact with staff at principal statistical agencies. Additionally,  OMB encourages agencies that are designing information collections  to collaborate with principal statistical agencies because they can help  improve survey design and methodology. For example, according to  OMB and Census Bureau officials, OMB encouraged the Corporation  for National and Community Service to work with the Census Bureau  and BLS to sponsor a supplement to the Current Population Survey  rather than a stand-alone survey. OMB indicated that sponsoring this  supplement likely resulted in cost savings, improved data quality, and  greater utility.

section_title: The Reliability of Information in OMB’s Information Collections Database Needs to Be Improved
paragraphs: One tool that OMB uses to facilitate its oversight and coordination  functions under PRA is an internal system called the Regulatory  Information Service Center and OIRA Consolidated Information System  (ROCIS), which contains information on all active collections and those  pending OMB approval. Agencies use the system to submit information  collection requests. This system also facilitates OIRA’s review of the  requests and underlies the information provided on the public website  Reginfo.gov. Agency submissions to OMB typically include a copy of the  data-collection instrument (e.g., a survey) and supporting documentation  that, in a standardized form, provides information on the collection, such  as the estimated annual burden hours and cost to the federal  government. Further, under PRA, agencies must certify that the collection  satisfies the act’s standards, for example that the collection avoids  unnecessary duplication. Making this information transparent and easily  accessible to other agencies facilitates coordination and can potentially  help agencies avoid duplication and identify opportunities for  improvement. Furthermore, OMB uses the information contained in its  internal system to track reviews of information collections, and to compile  quantitative data for the Information Collection Budget of the United  States Government.

Despite the benefits of this electronic system, our review identified some  discrepancies between the Reginfo.gov website’s data and the underlying  documentation for certain key variables. Specifically, we reviewed a  systematic random sample of 56 of the 555 collections in our scope and  checked the reported information for annual cost to the federal  government and annual burden hours. For 11 of the 56 information  collections, the information on cost or burden, or both, did not match  between the two sources. In cases where annual cost did not match, the  differences ranged from $1,000 to $19.3 million. In cases where annual  burden hours did not match, the differences ranged from 30 to almost  500,000 hours. OMB confirmed that the information in the external  Reginfo.gov system is the same as in its internal ROCIS system. As a  result, these discrepancies raise questions about the confidence that  users can have in both the internal and external databases and may  affect OMB’s ability to track information collection requests. OMB officials  told us that responsibility for ensuring data reliability is shared between  OMB and agencies. The Regulatory Information Service Center has  issued detailed guidance to agencies on how to upload information into  ROCIS, and the system has a function that allows agencies to check the  completeness of data for individual information collections to ensure that  no required data are missing. Entering this information is not always  straightforward, however, and some interpretation of the underlying  documentation may be required. The discrepancies that we identified  indicate that additional actions, such as edit checks, review by an  informed staff member, or increased clarification in supporting documents  are necessary to ensure the reliability of Reginfo.gov and ROCIS data.

section_title: Agencies Identify Duplication and Solicit Input to Enhance Efficiency
paragraphs: Our analysis indicated that agencies addressed PRA standards related to  duplication and public comment in their information collection requests to  OMB, and in many cases went beyond the actions specifically described  in PRA and related OMB guidance.

The elements of PRA most directly related to our review were identifying  duplication and soliciting external input on proposed collections. To  analyze agencies’ actions in these two areas, we reviewed a  generalizable sample of supporting statements from 106 active statistical  information collections administered to households and individuals.Each of the supporting statements we reviewed addressed those PRA  standards, as required, and in many cases included detailed descriptions,  the content of which we analyzed in order to identify the range of actions  that agencies took.

Although agencies must address how their proposed collections meet  PRA standards, the act and OMB guidance do not prescribe many  specific actions that agencies need to take in addressing these standards.  Regarding duplication, PRA does not dictate how agencies should  address the standard. Regarding external input, PRA does require that  agencies at a minimum provide notice in the Federal Register to allow the  public to comment on proposed collections as well as consult with  members of the public and affected agencies. OMB guidance expands  somewhat on ways that agencies can address these standards,  particularly in the case of surveys using statistical methods. However, just  as with PRA, much is left to the discretion of agencies and little is  specifically required. For example, OMB guidance states that agencies  should review existing studies and consult with survey methodologists  and data users.

Identifying potential duplication: Our analysis showed that agencies  took various steps to comply with the PRA requirement that information  collections do not unnecessarily duplicate an available information  source. Specifically, based on our analysis, we estimated the following for the universe of collections in our scope:

77 percent included detailed explanations of the actions taken to  identify potential duplication.

The 95 percent confidence interval for this estimate is (68, 85). not include detailed explanations were generally for information  collections that had unique scopes or other characteristics that made  them unlikely to duplicate existing information.

57 percent reported reviewing other surveys when looking for  duplication.seven other surveys that collected information similar to that of a  Current Population Survey supplement on tobacco use and explained  why the data from these surveys could not replace those collected  through the supplement.

For example, the National Cancer Institute identified

46 percent indicated that the agency considered administrative data  as a potential source of data.

About a quarter indicated that they consulted with other entities, such  as agencies, and a similar number reported that they conducted  literature searches. In addition, for six of the information collections in our sample,  agencies sponsored a collection in the form of a supplement to the  Current Population Survey rather than creating a stand-alone survey,  thus piggybacking onto another survey vehicle to potentially avoid  duplication.

The 95 percent confidence interval for this estimate is (32, 59). evaluate surveys’ data quality. In order to facilitate comparisons among  surveys, OMB encourages asking consistent questions, when possible,  about certain characteristics such as race and ethnicity. Further, when  considered from an individual’s perspective, duplication of survey  questions is relatively rare. This is because in a given year a very small  percentage of households are selected to participate in a single collection  within our scope. The likelihood that a household would be selected for  participation in more than one collection, and thus household members  be asked the same question more than once, is considerably lower.

The 95 percent confidence interval for this estimate is (46, 67). and sponsoring or participating in workshops, panels, or other  events.

Agencies in our sample reported making changes in response to input,  potentially resulting in improvements to their information collections. For  example, in response to recommendations made by the Committee on  National Statistics on a Current Population Survey supplement about food  security, ERS reported entering into an agreement with Iowa State  University to study food security measurement issues. This collaborative  project is exploring alternatives to an aspect of the supplement’s current  design, which could result in alternatives to methods used to estimate  food security prevalence and potentially improve measurement precision  and reliability. The U.S. Geological Survey also reported incorporating  changes in response to feedback on its Landsat Survey.

Agencies’ actions to find duplication and solicit input that we identified in  our review, as well as others that OMB may identify, could be useful for  OMB to share with other agencies that sponsor information collections.  Offering more-detailed guidance in a single document that outlines  different actions agencies can take to identify duplication and solicit input  would help ensure that agencies are aware of the various options. It  would also allow them to easily access and reference this information.  OMB could include this information in one of its periodic memorandums  related to compliance with the PRA. We previously reported on the  importance of establishing ways to operate across agency boundaries,  and promoting these actions is one way OMB can do this. Also, just as OMB’s guidance to agencies in complying with the Information Quality Act  gives agencies flexibility to determine the most appropriate actions, it is  important that any new guidance continue to give agencies discretion in  the number and types of actions they take to identify duplication and  solicit input. This is because the most appropriate actions will vary based  on the characteristics of the collection.

section_title: Interagency Committees Facilitate Collaboration, but Better Communication Could Increase Effectiveness
paragraphs: Interagency statistical committees offer opportunities for broader  collaboration to increase the efficiency of the federal statistical system.  Three key committees are the Interagency Council on Statistical Policy  (ICSP), the Federal Committee on Statistical Methodology (FCSM), and  the Statistical Community of Practice and Engagement (SCOPE), all of  which are either chaired or sponsored by OMB. Importantly, the  activities of the interagency committees are consistent with key  collaborative practices we identified in our previous work. For example,  each of these committees has defined roles and responsibilities, and the  committees serve as a vehicle for the agencies to operate across agency  boundaries. Specifically, ICSP serves an advisory function to the Chief  Statistician and focuses on broader issues related to the federal statistical  system. In addition, ICSP provides overarching guidance to FCSM and  SCOPE. FCSM investigates statistical practices and methodologies used  in federal statistical programs, while SCOPE focuses on cross-agency  activities of data management and dissemination. Table 1 provides an  overview of these committees.

The committees study statistical issues and methods through  subcommittees and working groups, most of which rely on volunteers  from member agencies who take on these responsibilities in addition to  their current job duties. The work of the subcommittees and working  groups has been useful to other agencies. For example, an FCSM  subcommittee produced a checklist that, according to OMB, is used  around the world to determine whether a public-use data product  sufficiently protects the confidentiality of individuals’ data.

The interagency committees use various methods to disseminate  information on their activities and products, but they do not do so in a  timely or comprehensive manner. The committees’ work is summarized in  OMB’s annual report Statistical Programs of the United States  Government, but the report does not always communicate key  information about it. For example, the fiscal year 2011 report states that  one of ICSP’s activities over the past year was identifying the highest- priority statistical-program improvements, but does not provide  information about all of these improvements. In addition, interagency  committees present information about their work at statistical seminars.  For example, according to OMB officials, FCSM has presented work at  the biennial FCSM Statistical Policy Seminars. Additionally, agency  officials noted that members of interagency statistical committees utilize a  limited-access web-based system to facilitate information sharing.  Information about FCSM’s work is also posted on the committee’s  website or the FedStats website. Neither ICSP nor SCOPE has a  dedicated website, though OMB believes that this is not necessary or  appropriate because the work of these groups is deliberative. While the  FCSM website offers the potential to effectively disseminate information,  it is not comprehensive or timely. For example, it provides links to the  sites of various interagency and advisory committees, including three  FCSM permanent working groups, but does not have pages for any of the  active FCSM subcommittees. Moreover, the websites do not appear to  be regularly updated with new products produced by the committees that  could be useful for other agencies. For example, the subcommittee on the  statistical uses of administrative data published a paper in April 2009  highlighting examples of successful data-sharing projects using  administrative data for statistical purposes, but this product is not yet  available on the FCSM website.

Providing more-comprehensive and timely information on interagency  activities could offer benefits. As identified in our previous work,  developing mechanisms to monitor and report on results is a necessary  element of a collaborative relationship.committee activities and products could offer benefits to those who are  not involved in committee activities, as well as committee members.  Membership in the committees is made up almost exclusively of  representatives from the 13 principal statistical agencies, so most  agencies are not directly involved in committee activities. It makes sense  that agencies that have statistics as their primary focus are the most- heavily involved, but those agencies for which statistics is a supporting  function to their primary mission, and possibly academics and the broader  public, could benefit from greater access to information and products  related to the committees’ work and priorities. More easily accessible  information would also benefit member agencies, as it would offer a  centralized place to maintain committee work and communicate priorities.  Much work goes into developing the committees’ products, and making  them easily accessible maximizes their value.

section_title: Administrative Data Could Help Improve Federal Surveys, but Continued Progress Is Needed on Access and Quality Issues
subsections: section_title: Administrative Data Have Greater Potential to Supplement, Rather than Replace, Federal Surveys
paragraphs: Administrative data, typically collected to administer a program or  business, are a growing source of information on individuals and  households. For example, the Social Security Administration collects data  on the earnings of U.S. workers from employers and the Internal Revenue  Service to calculate the amount of benefits for retired workers, spouses,  children, and other beneficiaries, while businesses obtain data, for  example, on item and amount of purchases when customers use credit  cards and store loyalty cards. According to the Census Bureau, the  amount of administrative data held by private companies exceeds the  amount held by the government. Researchers recently estimated that the  amount of digital data in existence, which includes some types of  administrative data such as retail customer databases, more than doubles  every 2 years. Administrative data have been identified as an important  resource for the future of the statistical system, as some of these publicly  and privately held data may be analyzed or reported with survey data to  yield greater value. Furthermore, the increasing capacity to store and  process administrative data has facilitated this potential use.

For decades, agencies have been working to expand the use of  administrative data in conjunction with data collected from surveys, but  certain characteristics of administrative data make it difficult to use them  to replace surveys or sections of surveys administered to households and  individuals. There is interest in exploring how administrative data may be  used to improve data quality, hold down costs, and reduce respondent  burden. For example, as part of the redesign of the Consumer  Expenditure Surveys, BLS is investigating the potential for replacing  some portions of the survey with external sources of expenditure data to  reduce respondent burden and potentially improve data quality. However,  agencies we contacted have not replaced surveys or sections of surveys  administered to households and individuals with administrative data  because data: (1) are often not representative of a survey’s population of  interest; (2) may not correspond to information collected through survey  questions; (3) are vulnerable to program cancellation or changes; and (4)  may take a long time to obtain, which delays use and in some cases  could cause agencies to miss required reporting dates.

Administrative data currently show greater promise for supplementing  federal surveys. Indeed, the agencies we contacted identified four major  opportunities to enhance surveys with administrative data in order to  create efficiencies and enhance data quality.administrative data include the following:   Current uses of

Creating new data products: Agencies link survey data and  administrative data to create new, more robust, statistical data  products, which increases efficiency in two key ways. First, according  to OMB and agency officials, agencies can use these new data  products to evaluate and potentially improve federal policies and  programs, especially those related to the source of the administrative  data, without adding to respondent burden. Second, combining  administrative data with survey data can increase efficiency by  enhancing previously collected survey data. For example, the National  Center for Health Statistics’s (NCHS) record-linkage program links  survey data from various health-related surveys to different  administrative datasets to create new data products for studying  factors that influence health-related outcomes, such as disability,  health care, and mortality.

Supplementing surveys’ sample frames: Using administrative data  to supplement surveys’ sample frames—the sources from which a  survey’s sample is drawn—can create efficiencies, reduce costs, and  enhance the quality of surveys. For example, the National Household  Food Acquisition and Purchase Survey uses administrative data from  the Supplemental Nutrition Assistance Program to develop a sample  frame of participating households to potentially include in the survey.  ERS officials said that using these data to help develop the survey’s  sample frame costs less than the alternative of screening a broader  group of respondents to determine if they are participating. In addition,  agencies can use administrative data to augment sample frames in  areas where the sample is not large enough to fully support a survey.  For example, the Census Bureau’s pilot project studying the potential  to use ACS data as a sample frame for the National Immunization  Survey used commercial data to supplement ACS data in a county  that had a limited ACS sample.

Comparing data to improve survey accuracy and design: By  comparing survey data to similar administrative datasets and  identifying reasons for any discrepancies that may exist, agencies can  improve the quality of survey data. For example, researchers  identified opportunities for improving surveys’ designs and  methodologies after agencies found that surveys of enrollment in  health-insurance programs provided lower estimates than those  compiled from administrative data. Agencies can also improve the  efficiency of their surveys by using administrative data as part of  nonresponse follow-up activities.

Modeling estimates: Agencies combine administrative data and  survey data to create, or model, estimates that are designed to be  more accurate than estimates based on survey data alone. The main  benefit of modeling is that it provides the ability to produce estimates  for smaller geographic areas than is possible using a survey alone.  For example, the Census Bureau conducts the Small Area Income  and Poverty Estimates Program to provide updated data on poverty  and income, which is used to administer federal programs and  allocate federal funds to local areas. The Census Bureau combines  survey data from the ACS with population estimates and  administrative data and has found that this approach produces  consistent and reliable data more reflective of current conditions than  data produced only by existing surveys.

section_title: Agencies Are Addressing Issues That Hamper Use of Administrative Data, but Additional Actions Could Facilitate Progress
paragraphs: Despite the benefits of using administrative data to supplement federal  surveys, agencies face five key constraints related to data access and  quality:

Statutory restrictions on data sharing: Federal and state statutes  sometimes prohibit or limit sharing of data for statistical purposes. In  cases where specified authorized uses do not include statistical use,  nothing short of a statutory change can overcome the constraint. In  other cases, statutes limit sharing to purposes related to program  administration. For example, the 2008 Farm Bill restricts access to  data on participants in certain nutrition-assistance programs to uses  for the “administration or enforcement” of the programs. Similarly,  the Higher Education Act of 1965, as amended, restricts federal  student aid data to purposes related to the “application, award, and  administration of aid.” However, agencies holding such restricted  data can differ on whether statistical uses are related to program  administration. The Census Bureau successfully negotiated access to  the nutrition assistance data because it could demonstrate that the  linked data would help the federal sponsor and state agencies  develop better measures of outcomes, such as poverty, inequality,  and the receipt of government transfers. Conversely, the Census  Bureau was unable to gain access to the federal student aid data for  statistical uses because the Department of Education did not consider  that any of the planned uses related to the program’s administration.

Consent: Individuals’ consent to allow their administrative and survey  data to be linked affects uses of administrative data for statistical  purposes. Seeking consent derives from a core concept of personal  privacy: the notion that each individual should have the ability to  control personal information about himself or herself. Moreover,  there can be issues regarding the privacy and confidentiality of data  collected for one purpose and used for another, and agencies use  different practices, wording, and level of detail to meet consent  requirements, according to OMB officials. At the time administrative  data are collected, an agency can inform individuals that their data  may be used for statistical purposes, but, according to ERS officials,  agencies collecting administrative data often do not consider possible  future statistical uses and therefore may not provide such notice.  Obtaining consent after data have been collected can be time- consuming and costly. In addition, an agency can ask survey  respondents for permission to link their survey data with certain  administrative data. Some respondents may not consent, which can  substantially limit the number of respondents eligible for linkage and  as a result potentially affect the quality of the linked data.

Costs and infrastructure: Because the primary cost of collecting  administrative data has already been incurred, using these data can,  in some cases, be more efficient and less costly than new survey  efforts. However, there still are costs to using administrative data for  statistical purposes, including up-front and ongoing investments to  purchase and maintain hardware and software to link data and protect  their confidentiality. Agencies identified various factors that can affect  costs. These include but are not limited to negotiations with the  agency holding the data, the quality of the administrative data, and the  ease with which they can be linked to other data. BLS officials said  that in some cases the costs of using administrative data with survey  data may outweigh any savings and that evaluation of administrative  data options always requires careful consideration of a wide range of  quality and cost issues, including the costs of specialized personnel  and infrastructure. According to an FCSM study that profiled  examples of successful statistical uses of administrative data,  agencies wanting to share data also may not have the necessary  staff, policies, or procedures. For example, negotiating data-sharing  agreements may require significant time. Moreover, many key  administrative datasets are held by states, further complicating the  data-sharing process because agencies have to negotiate under  different policies and procedures as well as work with numerous staff  across states.

Documentation of datasets: OMB and agency officials said that  agencies holding administrative data do not uniformly document  information about their datasets in a way that is always useful or  efficient for use outside of the agency. This lack of documentation of  datasets makes evaluating their potential for statistical uses  challenging. For example, definitions of key variables of research  interest or information about how frequently the agency updates the  data may not be available. ERS officials also noted that private  companies typically do not disclose detailed information about the  sources of their data, making it difficult to assess their quality. As a  result, agencies interested in using these data for statistical purposes  may have to spend additional time and resources to understand the  content and structure of the datasets.

Quality of data: Agency officials and experts identified reasons why  the quality of administrative data can vary, which can affect their  potential use with survey data. Specifically, different agencies may  use different systems, definitions, and time frames when collecting  administrative data. For example, states may collect and evaluate the  quality of data in different ways, making it complicated to aggregate  the data across states as well as to compare state-level data. In  addition, several factors can influence the accuracy of data reported in  administrative data. For example, agencies that collect data for the  purpose of program administration may be concerned with the  accuracy of only the variables used for such purpose. Moreover,  reporting incentives may influence data quality. For example,  individuals may underreport income on tax forms, and program  agencies may pay less attention to the accuracy of information  collected from applicants when it does not affect their participation in a  program.

Agencies and interagency committees have been taking numerous  actions to address these constraints. For example, ERS, in collaboration  with the Census Bureau, NCHS, and OMB is undertaking a pilot project to  address data quality concerns with state-level administrative data, and  FCSM is working on a project to clarify legal requirements for informed  consent (see fig. 3).

One theme that cuts across many of these efforts, and where additional  short-term actions could accelerate progress, is identifying ways to  facilitate the process of deciding whether to share data among agencies.  FCSM published a paper describing successful data-sharing  arrangements between various federal and state agencies. One of the  four core elements of success that FCSM identified in these  arrangements was mutual interest, in that each participant—in particular  the agency providing the data—evaluates a proposed data-sharing  agreement from its own perspective. On the one hand, agencies may  share data because the linked data can benefit program administration,  as noted earlier. On the other hand, OMB and agency officials noted that  agencies may decide against sharing because perceived disadvantages,  such as policy concerns and potential identification of weaknesses in  program administration, outweigh the possible benefits. In such a case,  an individual agency’s interests may be at odds with the broader  efficiency of the whole federal statistical system. As illustrated in figure 3,  FCSM and agencies are developing tools to approach these decisions in  a more standardized way, such as developing checklists for evaluating  the quality of administrative data and a template for executing data- sharing agreements. However, these individual tools focus on particular  aspects of data sharing—for example, the checklist focuses on data  quality. Separately, they may not be sufficient for agencies to efficiently  identify potential datasets with the greatest potential for mutual benefit  and address all factors involved in the decision-making process.

The benefits of having more-comprehensive centralized guidance could  include greater consistency, clarification, and efficiency. A more- comprehensive standardized framework that ties together existing tools  with additional resources in order to cover major aspects of the data- sharing process could bring consistency to the decision-making process.  Similar to the checklist that FCSM is developing for agencies to use in  evaluating data quality, the framework could include a template outlining  a list of key questions for all agencies involved in the proposed data  sharing, including federal and state agencies that hold data, to address  issues such as: (1) the steps to take to ensure data reliability; (2) any  statutory limitations on planned uses of the data (including confidentiality  protections); (3) whether consent has already been obtained for additional  use of the data, or how it will be obtained; and (4) methods to fully  account for the costs associated with obtaining and using the data. To be  comprehensive, such guidance would not need to be voluminous, but it  should identify each of these major aspects of data sharing, provide  advice to agencies, and reference any tools available to assist agencies  during the process. It should also be kept up-to-date, reflecting changes  in legislation or other factors that affect data sharing, as well as any new  tools that are developed. Although such a framework may not lead to  sharing in all cases, the framework could better ensure that agencies  weigh the related benefits and costs in a more balanced, consistent, and  transparent fashion. Such guidance could also clarify ways that agencies  could resolve disagreements over data sharing. It could also improve  efficiency, given that agency officials we spoke with cited examples in  which it took multiple years to reach a resolution on data sharing, by  helping agencies evaluate available data and determine those that have  the greatest potential for mutual benefit.

While agencies can take steps to address some constraints on sharing  data, in other cases only policy actions on the part of the executive  branch or Congress can lift barriers. One of the primary examples of such  action is Congress’s enactment of CIPSEA in 2002, which authorized the  Census Bureau to share selected business data with BLS and the Bureau  of Economic Analysis for statistical purposes. However, CIPSEA is limited  because the Census Bureau’s business data are based in large part on  tax data, and as a result the tax code would need to be amended for the  Census Bureau to also share these data with other statistical agencies.  There have been proposals to amend the tax code to further expand the  scope and coverage of CIPSEA, but action has not yet been taken by  Congress.

section_title: Prospects for Enhanced Use of the ACS with Other Surveys Are Mixed
subsections: section_title: The ACS Provides Unique Coverage of the Nation’s Population
paragraphs: The Census Bureau’s full implementation of the ACS in 2005 was a major  change to the statistical system. The survey is unique among other  surveys of households and individuals because of its size—the monthly  surveys add to an annual sample of 3.54 million addresses. The ACS  provides annual estimates of social and economic characteristics for all  areas of the country and is a primary source of information on small  areas, such as towns and tribal lands, down to the neighborhood level.  The ACS covers a broad range of topics, such as housing, education, and  employment. The information provided by the ACS was previously only  available once a decade from the decennial census long form, which the  ACS replaced. Users of ACS information include all levels of government,  the private and nonprofit sectors, and researchers. According to the  Census Bureau, ACS estimates are currently used to help allocate more  than $400 billion in federal funding annually. Table 2 lists some of the key  characteristics of the ACS.

Several of the ACS’s characteristics lend to its appeal for use for other  surveys, including that it produces annual estimates on a broad range of  topics at finer geographic levels than other surveys, and agencies and  others identified five areas of opportunity in which surveys can make use  of ACS data and resources. Two of these areas, which generally rely on  publicly-available ACS estimates and do not require changes to the  survey’s design or methodology, have the greatest potential for  widespread use. The Census Bureau has provided users with various  resources to guide their use of ACS estimates. These include a guide to  comparing estimates, handbooks directed to specific types of users,  training presentations, and a tutorial. The two areas with the most  potential for use are as follows:

Evaluating and supplementing other surveys’ results: Survey  administrators and data users can also use ACS estimates to  evaluate information collected by other surveys. For example, survey  administrators can use ACS information to evaluate the quality of  responses to other surveys that include some questions that are the  same as or similar to ACS questions. Additionally, data users and  survey administrators can use ACS data to supplement information  collected by other surveys. For example, a recent report based on  analysis of ACS data describes how median earnings vary by the field  in which people obtain their bachelor’s degrees. Such information  can complement results from other surveys. In this case, NCSES also  produces information on earnings by degree type, based on  information in its Scientists and Engineers Statistical Data System  database, which contains data on people with a science or  engineering degree and those who work in related fields. NCSES  information collection is less frequent than ACS estimates and  pertains to a more-narrowly defined population, but allows more  detailed analysis of issues such as how people use their college  degrees at work. Together, these two sources of information offer  more-timely and more-detailed information than a single source.

Designing other surveys: There is also widespread potential to use  ACS data to more-efficiently design other surveys. Because many of  the topics included in the ACS are covered in more detail by other  surveys or relate to other surveys’ target populations, survey  administrators can use ACS estimates at different demographic or  geographic levels to stay up-to-date on changes that may affect their  surveys. These estimates can also be used when designing and  selecting a survey’s sample. Census Bureau officials told us that,  when designing a survey, survey administrators can use the data to  guide the selection of a survey’s sample so that it better represents  individuals or households with certain characteristics. For example,  the Survey of Income and Program Participation can use ACS  estimates at different demographic or geographic levels to identify and  more-efficiently sample geographic areas with disproportionately large  numbers of low-income households because this is a population of  interest for the survey. Because these data are available for small  geographic areas, agencies can use the data when samples include  more-local geographic levels.

section_title: Uses of ACS That Require Design and Methodology Changes Have Limited Potential
paragraphs: Agencies and others identified three uses of ACS data and resources  that, while offering potential benefits to other surveys, face such  constraints that more widespread use is likely not possible under current  ACS design. These uses are more intensive than the ones described  above, in that they affect the survey’s design and methodology or  respondent burden, or both. Because the ACS has a large sample size  and a complex methodology, there are logistical challenges involved in  changing its design and methodology. Additionally, any changes that  affect the survey’s respondent burden also have limited potential, as there  are already concerns about the burden that the ACS places on  respondents. Uses with more-limited potential are as follows:

Adding or modifying ACS content: Adding a question to the ACS or  modifying existing questions can improve the efficiency of other  surveys, though doing so involves trade-offs with factors such as  respondent burden. This use of ACS could provide information that  would inform the design of other surveys or facilitate the use of ACS  data for another survey’s sample frame. For example, NCSES worked  with the Census Bureau to add a question to the ACS about the field  in which respondents earned their bachelor’s degrees in order to  identify respondents that are in the target population for the National  Survey of College Graduates. Despite the potential benefits of adding  or modifying ACS content, adding a question to the ACS would  increase respondent burden and have operational impacts, as it  requires the Census Bureau to change the questionnaire design and  processing and editing systems. If these actions result in additional  pages for the questionnaire, it could affect costs and the response  rate. Modifying questions poses an additional challenge because ACS  estimates reflect multiple years of data, and a change in a question  may affect the Census Bureau’s ability to cumulate data.

Adding supplements to the ACS: Another possible use of the ACS  by other surveys is adding supplements to the ACS, though this use  faces several obstacles. While the ACS currently does not include  supplements, doing so could enable surveys to leverage the  resources of the ACS. Other surveys, such as the Current Population  Survey, allow other agencies or entities to sponsor supplemental  surveys that are added on to the survey’s core set of questions.  According to officials at BLS, which sponsors the Current Population  Survey, in their experience it costs less to add a supplement to an  existing survey than to conduct a separate stand-alone survey.  Additionally, the agencies sponsoring the supplements gain the  benefit of the experience of BLS or Census staff, or both, in designing  and implementing surveys. Although the Current Population Survey  successfully incorporates supplements, the ACS is different in several  key ways, and adding supplements to the ACS would involve  significant challenges. For example, the ACS is mandatory, meaning  that responses are required by law. Assuming a supplement to the  ACS would be voluntary, Census Bureau officials told us that they  would have to determine how to distinguish between the mandatory  and voluntary sections, which would create complexity. Additionally,  the Census Bureau processes ACS data on a yearly basis and does  not have a process in place for producing estimates from a single  month’s data, which would be a challenge if the supplement was  administered along with only 1 month’s ACS mailout. Finally, including  supplements raises concerns about respondent burden and  respondent fatigue. BLS officials noted the potential of matrix  sampling, in which a set of additional questions, as in a supplement, is  added to a month of collection (or all months) but differs from a  supplement in that it is only administered to a subset of the survey  sample in a given collection period. This option could reduce burden  and increase efficiency; however, such an option involves logistical  considerations in administering the survey and processing the data,  and adds complexity for analysts using the data for research.

Creating sample frames: Using ACS data to develop sample frames  for follow-on surveys has been identified as a potential use of ACS  data, but several factors limit this use. This involves using ACS data  to identify ACS respondents with certain characteristics for potential  inclusion in a follow-on survey and requires the approval of the  Census Bureau and OMB. At present only NCSES uses ACS data  for this purpose. Agency officials told us that using ACS data to create  a sample frame, as opposed to census long-form data, which they  used previously, has improved the agency’s coverage of its target  population and has reduced costs and respondent burden.benefit of this use is expanded analysis, as agencies, under  appropriate Title 13 restrictions, can analyze respondents’ answers to  the ACS along with responses to the follow-on surveys, and can  analyze the characteristics (from ACS data) of those who do and do  not respond to the follow-on survey to determine if they have different  characteristics, which might cause bias in the survey. Surveys such  as the National Survey of College Graduates that focus on  populations that are costly to identify are likely to realize higher gains  in efficiency from using ACS data for this purpose. Despite these  benefits, opportunities for other surveys to use ACS data for this  purpose are limited. ACS’s sample size, although large compared to  most surveys, can be too small for another survey to use for a  sampling frame. This is especially an issue if a survey targets a rare  population or targets members similar to those of surveys already  drawing from the ACS for their frame, because there would be too  much chance of drawing individuals into both follow-on surveys, and  current policy does not allow for that. Census Bureau policy states  that, when agencies conduct follow-on surveys, they may not contact  any member of a household that has already responded to the ACS  and also had a member selected for a follow-on survey. With certain  households in the ACS excluded from potential selection, it becomes  more difficult for other surveys to draw samples because the data no  longer reflect respondents with certain characteristics.

In the long run, more-intensive uses of ACS data and resources may  require difficult decisions and entail trade-offs with factors such as cost  and respondent burden. Further, they risk affecting ACS response rates  and overall data quality. However, redesign of the scope and  methodology of ACS might overcome some of these constraints. After the  release of the survey’s first 5-year data products in 2010, the Census  Bureau and others began evaluating the survey and exploring options for  increased uses. In addition to its own evaluation of the ACS, at the  Census Bureau’s request the National Academy of Sciences is organizing  workshops with data users to assess the survey. Also, OMB, in  cooperation with the Census Bureau, created an ACS subcommittee of  the ICSP with the goal of investigating trade-offs of options such as  adding questions to the ACS and rotating questions in and out of the  survey. If the Census Bureau changes the survey’s design or  methodology, these changes may become more feasible.

section_title: Conclusions
paragraphs: To ensure the provision of high-quality, timely statistical data for public-  and private-sector users, OMB and the agencies that make up the federal  statistical system must continue to identify opportunities for efficiency in  federal surveys of households and individuals. Most of the surveys and  other information collections in our scope have relatively modest costs,  but challenges such as declining survey response rates will strain  available resources unless agencies find more-effective and less-costly  ways to collect and analyze the needed information, while maintaining  critical protections of respondents’ privacy and confidentiality. In the long  term, addressing the key challenges and constraints that agencies have  identified will necessitate broader public debates and policy decisions  about balancing trade-offs among competing values, such as quality,  cost, timeliness, privacy, and confidentiality. In the short term, our review  indicated that two promising avenues to sustain the progress that OMB  and agencies are making include (1) facilitating collaboration and  coordination among agencies and (2) combining existing data from both  survey and administrative sources.

The federal statistical system already exhibits many collaborative traits  and practices, in particular through projects sponsored by OMB and  interagency committees that facilitate coordination and the development  of new policies and tools. However, additional efforts could help enhance  the effectiveness of these efforts. Going forward, it will be important for  OMB to supplement existing guidance to clarify the range of options  available to address PRA standards. Supplementing the guidance could  increase agencies’ awareness of these options, in particular those that  were cited less frequently. At the same time, interagency committees  could do more to improve accessibility and timeliness of their work  products. Doing so could maximize the usefulness of committees’ work.  Additionally, OMB’s ability to oversee and coordinate information  collections across the government would benefit from additional steps to  ensure the reliability of data on collections’ costs and burdens. Doing so  would also benefit users of the information, whether they access it  through the website or though OMB reports.

Agencies identified multiple ways that combining survey and  administrative data can improve the efficiency and quality of their work,  and they are already pursuing such opportunities. Importantly, they have  demonstrated that using existing datasets to supplement each other can  add value for all agencies involved in data sharing. But agencies also  face serious constraints to expanded uses of existing data. One of the  more-significant barriers is the complexity of the process through which  they make decisions about sharing data. Though agencies and  interagency committees are working to create tools to facilitate parts of  this process, more-comprehensive and centralized guidance for agencies  to follow when negotiating and making decisions regarding data-sharing  opportunities could help facilitate the process.

A standard protocol or framework could accelerate progress in this area  by helping agencies to (1) evaluate the growing array of administrative  data to identify those datasets that have the greatest potential for mutual  benefit of the participating agencies, and (2) consider a common set of  criteria and key questions when weighing the pros and cons of sharing  data. A key benefit would be to encourage agencies to consider, in a  uniform manner, all relevant aspects of these decisions, such as whether  or not proposed uses would be consistent with applicable law, maintain  confidentiality protections, be cost-effective, and serve to increase the  broader efficiency of the federal statistical system.

section_title: Recommendations for Executive Action
paragraphs: In order to maintain progress in maximizing the efficiency of existing data  sources, we recommend that the Director of OMB, in consultation with the  Chief Statistician, work with the ICSP to take the following four actions:  To improve the broader efficiency of the federal statistical system and  improve communication among agencies and others, when OMB next updates guidance on agency survey and statistical  information collection and dissemination methods, include additional  details on actions agencies can take to meet requirements to identify  duplication, to consult with persons outside of the agency, and  address other requirements as appropriate; and  create new methods or enhance existing methods to improve the  dissemination of information and resources produced by interagency  statistical committees. For example, such enhancements could  include increasing the timeliness and availability of information on  websites to better capture the full range of products and identify  committee priorities.

To increase the reliability of the information presented on the Reginfo.gov  website and in OMB’s internal system,  implement quality-control procedures designed to identify and remedy  any differences between cost and burden information provided on the  website and in the related supporting statement documentation that  underlies this information.

To accelerate progress in sharing administrative data for statistical  purposes, where appropriate, develop comprehensive guidance for both statistical agencies and  agencies that hold administrative data to use when evaluating and  negotiating data sharing, such guidance should include key questions  focused on issues such as statutory authority, confidentiality, cost,  and usefulness in order to ensure agencies consider all relevant  factors and the broader interest of the federal government.

section_title: Agency Comments and Our Evaluation
paragraphs: We provided a draft of this report to the Secretaries of Commerce and  Health and Human Services, the Director of OMB, the Commissioner of  BLS, the Administrator of ERS, and the Director of the National Science  Foundation for their review and comment.  We received written comments  on the draft report from the Secretary of Commerce that are reprinted in  appendix V.  We also received comments from OMB staff that are  summarized below.  The Department of Health and Human Services,  BLS, National Science Foundation, OMB, and agencies on the ICSP also  provided technical comments and suggestions that we incorporated as  appropriate.

Commerce stated that our observations illuminate future opportunities for  using administrative records within the federal statistical system to  increase efficiency and better meet informational needs and that our  suggested actions would enhance the ability of statistical agencies to  realize these opportunities. Regarding our recommendation on standard  protocols and procedures to facilitate data sharing, the department noted  that policies and other initiatives can also play a role in achieving  cooperation. Finally, the department noted that our report’s  acknowledgement of related concerns about the quality of administrative  data, and the level of support and resources necessary to maintain a  statistical and administrative data infrastructure, underscore the  importance of our recommendations.

OMB generally agreed with our recommendations and said that the  agency hopes to pursue these in the future.  More specifically,

OMB agreed that it is worth considering good practices for  reducing duplication.  As we suggested, OMB indicated that when  its survey guidance is next updated it will include additional details  and examples of actions agencies can take to identify duplication  and consult with persons outside the agency.

OMB said that it shared our concerns about timely and easily  accessible dissemination of information resources produced by  interagency statistical committees, and that our recommendation  underscores the need for addressing this issue.

With respect to our recommendation that OMB implement quality- control procedures designed to identify and remedy any  differences between cost and burden information provided on  Reginfo.gov and in the related supporting statement  documentation that underlies this information, OMB noted that  PRA requires OMB to weigh the burdens imposed on the public by  information collections against the legitimate needs of the federal  agencies. OMB said that this requires a careful assessment of the  estimates of paperwork burden that agencies provide to OMB as  part of their information collection requests and, further, that these  estimates are subject to public scrutiny and comment in Federal  Register notices, in the PRA statements provided on information  collections, and on Reginfo.gov. OMB pointed out that, because  the burden estimates provided on Reginfo.gov and in the  underlying supporting statements are all made public,  discrepancies such as those found by us are public as well.  OMB  said that it will investigate and address any such discrepancies  that are brought to its attention by GAO or any member of the  public.

Finally, OMB concurred that administrative records can be a  valuable supplement to, though usually not a replacement for,  household surveys. OMB believes that our recommendation to  develop comprehensive guidance for statistical and administrative  agencies to use when evaluating and negotiating data-sharing  agreements would be constructive, but cautioned that this involves  a very complex set of issues and said it will take some time to  develop such guidance.

As agreed with your office, unless you publicly announce the contents of  this report earlier, we plan no further distribution until 30 days from the  report date. At that time, we will send copies to the Commissioner of the  Bureau of Labor Statistics (BLS), the Director of the U.S. Census Bureau,  the Administrator of the Economic Research Service (ERS), the Secretary  of Health and Human Services, the Director of the National Science  Foundation, the Director of OMB, the Secretary of Commerce, and the  Under Secretary of Economic Affairs. In addition, the report will be  available at no charge on the GAO website at http://www.gao.gov.

section_title: Appendix I: Scope and Methodology
paragraphs: The objectives of this report were to (1) review the ways in which the  Office of Management and Budget (OMB) and agencies identify  opportunities for improvement and increased efficiency of selected  information collections; (2) evaluate opportunities and constraints for the  statistical agencies to use administrative data in conjunction with selected  surveys; and (3) evaluate ways in which American Community Survey  (ACS) data and resources can be used in selected surveys, and the  associated benefits and constraints.

To achieve our objectives, we focused on statistical information  collections administered to households and individuals and subject to the  Paperwork Reduction Act (PRA), which requires OMB approval of certain  federal data collections. Although in many cases the information and  views provided by agencies during our review and our general findings  may also apply to statistical information collections outside of our scope,  such as those administered to businesses, all of the specific collections  and surveys we reviewed were administered to households and  individuals. The majority of the collections within our scope include a  survey, though some also include other methods of information collection  such as focus groups. To examine the issues related to our objectives,  we performed case studies of five federal surveys: the Consumer  Expenditure Surveys, sponsored by the Bureau of Labor Statistics; the  National Health and Nutrition Examination Survey and the National Health  Interview Survey, both sponsored by the National Center for Health  Statistics, part of the Centers for Disease Control and Prevention; the  National Survey of College Graduates, sponsored by the National Center  for Science and Engineering Statistics, part of the National Science  Foundation; and the Survey of Income and Program Participation,  sponsored by the Census Bureau. We selected these surveys based on  several factors, such as their size and cost and whether they use or have  the potential to use administrative data or ACS data.

For the first objective, to review the ways in which OMB and agencies  identify opportunities for improvement and increased efficiency of  selected statistical information collections, we examined the PRA, OMB  guidance to agencies, and prior GAO work on the federal statistical  system. We interviewed officials at OMB and the four agencies that  administer the case-study surveys to learn about coordination among  agencies, efforts agencies take to identify improvement, and OMB’s role.  We also interviewed officials at the Department of Agriculture’s Economic  Research Service, which is a member of several interagency statistical  committees and the lead agency for the Statistical Community of Practice  and Engagement. In addition, we interviewed experts on the federal  statistical system to learn about their perspectives on the efficiency of the  federal statistical system and agency and OMB coordination. In  evaluating OMB, agency, and interagency actions, we used as criteria the  requirements of the PRA and practices identified in prior GAO work on  agency collaboration.

To address the second objective, to evaluate opportunities and  constraints for agencies to use administrative data in conjunction with  selected surveys, we reviewed statutes that govern the sharing and use  of administrative data, documentation from case-study surveys, and  various papers and reports. We interviewed officials at OMB and experts  in the field of federal statistics to learn about their perspectives on the  current and potential uses of administrative data. We also interviewed  officials at the Economic Research Service and the agencies that sponsor  the case-study surveys to learn about ways in which their surveys use or  could potentially use administrative data. For this objective and the third  we used OMB guidance, relevant statutes, and prior GAO work as criteria  in our evaluation.

For the third objective, to evaluate the ways in which ACS data and  resources can be used in selected surveys, we reviewed Census Bureau  documentation, National Science Foundation reports, prior GAO work,  and reports issued by the Committee on National Statistics. We  interviewed officials at the Census Bureau, which sponsors the ACS, and  at OMB to learn about their perspectives on potential uses of the survey  and its data. We also interviewed officials at the Economic Research  Service and the agencies that administer the case-study surveys to learn  about ways in which their surveys use or could potentially use ACS data  and resources, and experts in the field of federal statistics to learn about  their assessment of the uses and potential uses of the ACS.

To gain a broader perspective on the information collections in our scope  and to inform our work across all three objectives, we obtained and  analyzed publicly-available data from Reginfo.gov, a government website  that provides access to information on agency requests for OMB approval  of information collections. We used the website’s search feature to  download all of the collections that were classified as (1) active, meaning  that they are currently approved by OMB for use by agencies; (2)  employing statistical methods; and (3) directed to households and  individuals. We downloaded data on all information collections that met  these criteria from Reginfo.gov on two dates, May 17, 2011, and  September 22, 2011.

We performed more in-depth analyses of the 507 information collections  in our May 17, 2011, download. First, we reviewed the supporting  statements for each of these collections, and on the basis of information  in these documents classified them according to the subject matter on  which they focus. Next, we grouped the collections into categories,  based on information on the sponsoring agency in Reginfo.gov and the  supporting statements. Depending on the sponsoring agency, we put the  collections into one of four categories: (1) those that are sponsored by  one of the 13 principal statistical agencies; (2) those that are sponsored  by another agency that shares a parent agency with one of the 13  principal statistical agencies (for example, agencies in the Department of  Health and Human Services would fall into this category because it is the  parent agency of the National Center for Health Statistics); (3) those that  are not a principal statistical agency and do not share a parent agency  with one; and (4) unknown, for those whose sponsoring agency we could  not determine based on the available information. We also used the  information in the supporting statements to determine if the collections  included a survey component and found that 481 of the 507 did.

We divided the 481 collections that included a survey component into  three strata that reflect the type of sponsoring agency. Of the 481, we  were not able to determine agency type for 7 collections so we dropped  these records, leaving a population of 474 statistical information  collections. The number of collections by stratum is shown in table 3. In  order to estimate the prevalence of certain characteristics in this  population—for example, the percentage of information collections for  which the sponsoring agency reported steps taken to identify potential  duplication—we drew a stratified sample of 106 collections. Within each  stratum, we estimated the sample size required to yield a 95 percent  confidence interval of plus or minus 14 percent around such an estimate.  For the overall population of 474, the approximate precision for an  estimated percentage of 50 percent is plus or minus 8.4 percent, at the 95  percent level of confidence.

We reviewed the supporting statements of each of the information  collections in our sample of 106, focusing on agencies’ reported efforts to  identify duplication and to consult with persons outside the agency to  obtain their views. Because agencies follow a standard format in  preparing supporting statements, we focused our analysis on the sections  of the supporting statements in which OMB instructs agencies to include  this information (sections 4 and 8, respectively, of section A of the  supporting statement). To review agencies’ reported actions, we used a  data-collection instrument that contained a series of “yes-no” questions  about the types of efforts reported. For example, we reviewed whether  agencies had reported considering administrative data as a potential  source of duplication, and whether agencies reported that they had  consulted with other agencies when describing consultations outside of  the agency. We did not evaluate whether agencies actually took the  actions they reported taking. Estimates produced from the sample of the  collections are subject to sampling error. We express our confidence in  the precision of our results as a 95 percent confidence interval. This is the  interval that would contain the actual population value for 95 percent of  the samples we could have drawn. As a result, we are 95 percent  confident that each of the confidence intervals in this report will include  the true values in the study population.

We took several steps to evaluate the reliability of the data we accessed  through the Reginfo.gov website. We interviewed OMB officials and  reviewed documentation of the Reginfo.gov website and the Regulatory  Information Service Center and OIRA Consolidated Information System,which is the system that agencies use to track information collection  requests and that underlies information provided on Reginfo.gov. As part  of our review of the subject matter of the collections in the May 17, 2011,  download, we confirmed that the collections were within our scope. We  also used the information in the September 22, 2011, download to  evaluate the reliability of data on collections’ cost and annual burden. To  do this, we drew a systematic random sample of 56 (approximately 10  percent) of the 555 collections in the download.

We found a number of inconsistencies between the cost and burden  information available on the website and that provided in supporting  statement documentation. According to an official at OMB, the two  sources should match, but the supporting statement documentation is  more accurate than that on the website. On the basis of our assessment,  we determined that the information from the website was not sufficiently  reliable for the purpose of describing the annual cost or annual burden to  respondents of the collections in our scope. However, through this review  and the other steps we took, we found that the other information provided  on the Reginfo.gov site was sufficiently reliable for our other intended  purposes of identifying the collections within our scope and obtaining  information on their subject matter and reported actions taken to identify  unnecessary duplication and solicit input from outside persons and  entities.

Because the cost information on the Reginfo.gov website was not  sufficiently reliable, we used cost information from the supporting  statements of the collections in our sample to provide background  information on the costs of the collections in our scope. In addition to  using information from the supporting statements in our initial sample of  56 collections, we drew another systematic random sample of 56  additional collections from the September download. In total, we obtained  cost information from the supporting statements of 112 (approximately 20  percent) of the 555 collections in our scope that were active as of our  September 22, 2011, download.

We conducted this performance audit from December 2010 until February  2012 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.

section_title: Appendix II: Description of Case-Study Surveys
subsections: section_title: Consumer Expenditure (CE) Surveys: Quarterly Interview Survey (CEQ) and Diary Survey (CED)
paragraphs: Purpose: To collect information on expenditures and households’  characteristics  Sponsoring agency: Bureau of Labor Statistics (BLS)

This amount reflects the approximate fiscal year 2010 cost of collecting, processing,  reviewing, and publishing data collected through the CE Surveys. Survey costs vary  somewhat from year to year.

BLS estimates that respondents will take an average of 60 minutes to complete one  interview survey of the CEQ. Since the CEQ is administered to the same sample of  households four times in a year, the annual burden for respondents who complete all four  surveys is roughly 4 hours. In addition, a certain number of respondents who complete the  interview surveys are reinterviewed, a process that adds 10 minutes to these selected  respondents’ burden times.

Price Index, the most widely used measure of inflation.government agencies, private companies, policymakers, and researchers  use data from the CE Surveys in a variety of ways. For example, the  Department of Defense uses data from the CE Surveys to update cost-of- living adjustments for military families. Congressional committees also  use the data to inform decision making, such as the potential effect of  increases in the minimum wage.

section_title: National Health and Nutrition Examination Survey (NHANES)
paragraphs: NCHS estimates that the annual cost to the federal government of NHANES for fiscal  year 2010 was $37.8 million, including both direct and reimbursable funding provided by  other agencies for NCHS statistical services. Survey costs vary somewhat from year to  year.

NCHS estimates that the total annual burden for the NHANES is 37,626 hours, including  screening, household interviews, physical examinations, and any follow-up interviews. In  addition, tests of procedures and special studies account for an additional 12,000 hours,  for a total annual burden of 49,626 hours. NCHS estimates that respondents who  participate in all aspects of the NHANES, including the screener survey, household  interview, and physical examination, can expect a burden of 6.7 hours. In addition to those  who complete all aspects of the NHANES, some respondents may only participate in the  screener survey and be screened out of the sample, while other respondents may  participate in the screener survey and the household interview but not the physical  examination. NCHS includes all respondents at these varying levels of participation in its  calculation of the annual burden hours.

Target population: Nationally-representative sample of individuals of all  ages  Uses of data: According to NCHS documentation, a variety of users,  including federal agencies, research organizations, universities, health- care providers, and educators, use NHANES data. For example, the Food  and Drug Administration uses NHANES data to determine whether  changes are needed to federal regulations. In addition, use of NHANES  data informs key decision making. For example, according to NCHS  documentation, NHANES data on lead levels in blood were instrumental  in developing the policy to eliminate lead from gasoline and in food and  soft drink cans. As part of its broader data-linkage program, NCHS links  NHANES survey data to multiple administrative datasets, such as the  National Death Index (a centralized index of state death record  information) and Medicare and Medicaid claims from the Centers for  Medicare and Medicaid Services. The National Death Index linkages give  researchers an opportunity to analyze mortality differences among  subgroups defined using the survey information. Similarly, the Medicare  and Medicaid claim linkages provide an opportunity to examine health  conditions, utilization, and costs among subgroups defined using the  survey information. Additionally, according to NCHS officials, NCHS is  currently conducting a pilot study to link NHANES data on participants  from Texas to administrative data on food assistance.

section_title: National Health Interview Survey (NHIS)
paragraphs: Purpose: To monitor the health of the U.S. population  Sponsoring agency: National Center for Health Statistics (NCHS),  Centers for Disease Control and Prevention  Annual sample size (estimated): 35,000 householdsAnnual cost to the federal government (estimated): $32.2 millionAnnual burden hours (estimated): 34,977 hours Target population: Nationally-representative sample of households,  collecting data on all members of each household  Uses of data: According to NCHS documentation, government agencies,  policymakers, researchers, and academics use NHIS data for a variety of  purposes, such as identifying health problems and evaluating health  programs. For example, policymakers used NHIS data to shape the  Centers for Disease Control and Prevention’s cervical-cancer screening  policy. In addition, other agencies can use the NHIS as a sample frame  for their surveys. Lastly, as part of its broader data-linkage program,  NCHS links NHIS survey data to multiple administrative datasets,  including those it uses for linkages with NHANES data, such as the  National Death Index and Medicaid and Medicare claims.

section_title: National Survey of College Graduates (NSCG)
paragraphs: NCHS estimates that the total annual burden of the NHIS was 34,977 hours for 2010  and 2011. NCHS estimates that a single respondent who completes all portions of the  NHIS for a household can expect a time burden of one hour. Some respondents who  complete all portions of the NHIS are asked to take a short reinterview survey, a process  that adds 5 minutes to these selected respondents’ burden times. In addition to those who  complete all portions of the NHIS, some respondents may only participate in a screener  survey and be screened out of the sample, which NCHS estimates takes 5 minutes per  respondent. NCHS includes all respondents at these varying levels of participation in its  calculation of the annual burden hours.

Cost to the federal government (estimated): $13.3 millionBurden hours per administration (estimated): 34,792 hours Target population: Individuals in the United States who have a bachelor’s  degree in science, engineering, or health, and those who have a degree  in another field but work in science, engineering, or health occupation.

Uses of data: According to National Science Foundation documentation,  information from the NSCG is used by researchers and policymakers.  Government agencies use the data to assess available scientific and  engineering resources and inform the development of related policies.  Additionally, educational institutions use NSCG data to inform the  establishment and modification of curricula, and businesses use the data  to develop recruitment and compensation policies.

section_title: Survey of Income and Program Participation (SIPP)
paragraphs: This estimate is based on the assumption that 83,500 individuals will respond to the  survey and each respondent will take 25 minutes to complete it.

The Census Bureau estimates that the production cost for all parts of the SIPP in fiscal  year 2011 is $50.1 million. Survey costs vary somewhat from year to year.

Annual burden hours (estimated): 143,303 hours All  Target population: Nationally-representative sample of households. household members 15 years old or over are interviewed for the survey.

Uses of data: According to the Census Bureau, SIPP data are used by  agencies such as the Department of Health and Human Services and the  Department of Agriculture, as well as economic policymakers, Congress,  and state and local governments, to plan and evaluate government  social-welfare and transfer-payment programs.

The SIPP is limited to the U.S. civilian, noninstitutionalized population, and as a result  excludes certain segments of the population, such as active-duty military members living  on bases and prisoners.

section_title: Appendix III: Selected Statutes Related to Information Collection
paragraphs: Selected statutes that regulate the collection and dissemination of  information include the following.
subsections: section_title: Governmentwide Statutes
paragraphs: The Information Quality Act of 2000 requires, among other things, that  the Office of Management and Budget (OMB) develop and issue  guidelines that provide policy and procedural guidance for federal  agencies for ensuring and maximizing the quality of the information  they disseminate. These guidelines include steps designed to assure  objectivity and utility of disseminated information. See 44 U.S.C. §  3504(d)(1); OMB guidelines are at  http://www.whitehouse.gov/omb/info_quality_iqg_oct2002/.

The Privacy Act of 1974, as amended, and the privacy provisions of  the E-Government Act of 2002 specify requirements for the protection  of personal privacy by federal agencies. The Privacy Act places  limitations on agencies’ collection, disclosure, and use of personal  information maintained in systems of records. See 5 U.S.C. §§ 552a  and 552a note. The E-Government Act requires agencies to conduct  privacy impact assessments that analyze how personal information is  collected, stored, shared, and managed in a federal system. See 44  U.S.C. § 3501 note.

The Confidential Information Protection and Statistical Efficiency Act  (CIPSEA) of 2002 focuses on confidentiality protection and data  sharing. It requires that information acquired by an agency under a  pledge of confidentiality and for exclusively statistical purposes be  used by the agency only for such purposes and not be disclosed in  identifiable form for any other use, except with the informed consent  of the respondent. It also authorizes identifiable business records to  be shared for statistical purposes among the Bureau of Economic  Analysis, Bureau of Labor Statistics, and the Census Bureau. See 44  U.S.C. § 3501 note.

section_title: Agency-Specific Statutes
paragraphs: Agency-specific statutes also guide federal data collection and use.  For example, the Census Bureau conducts the census and census- related surveys such as the American Community Survey under Title  13 of the U.S. Code, which gives the Census Bureau the authority to  request and collect information from individuals but also guarantees  the confidentiality of these data and establishes penalties for  unlawfully disclosing this information. Unless specifically authorized,  these provisions preclude the Census Bureau from sharing identifiable  census information with other agencies. See 13 U.S.C. § 9. Title 15 of  the U.S. Code permits the Secretary of Commerce to conduct studies  on behalf of other agencies and organizations. Identifiable data from  surveys conducted under Title 15 authority are subject to the  sponsoring agency’s legislation and confidentiality requirements. See  15 U.S.C. § 176a. Statutes and regulations specific to other agencies  also affect collection and sharing of data.

Section 6103 of the Internal Revenue Code provides that federal tax  information is confidential and may not be disclosed except as  specifically authorized by law.

Section 308(d) of the Public Health Service Act requires that  identifiable information obtained by the National Center for Health  Statistics be used only for the purpose for which it was collected  unless consent is obtained for another purpose, and it prohibits the  release of identifiable information without consent.

Other legislation such as the Family Educational Rights and Privacy  Act, which protects the privacy of student education records, can  affect federal data-collection efforts. See 20 U.S.C. § 1232g.

Question-summary annotations: questions: question: What is the role of the OMB?
answer: The Office of Management and Budget (OMB), agencies, and interagency statistical committees have distinct roles in identifying opportunities to improve federal information collection efforts.
child_questions: question: What authority do they hold?
answer: OMB exercises several authorities that promote the system’s efficiency, including overseeing and approving agency information collections.

question: How is OMB collection information made public?
answer: The website Reginfo.gov provides the public with information, such as cost and burden, on collections that OMB reviews, though GAO’s review identified some discrepancies in selected items.

question: What advice does OMB give?
answer: OMB periodically issues guidance to agencies on complying with federal requirements for information collections, but this guidance generally does not prescribe specific actions to take.

question: What did the GAO find on the OMB's documentation?
answer: GAO’s analysis of agencies’ documentation of active surveys indicated that 77 percent included detailed descriptions of efforts to identify duplication, while those that did not tended to be for collections that are unlikely to duplicate existing information; and 75 percent reported actions beyond those required by statute to solicit external input.
child_questions: question: What advice did the GAO have from this review?
answer: OMB, through enhanced guidance, could promote additional awareness of options agencies can take to identify duplication and solicit input.

question: Why are interagency committees important for collaboration?
answer: Interagency committees, which primarily draw members from the 13 agencies that have statistics as their primary focus, are particularly important in helping ensure collaboration.
child_questions: question: What projects do these committees have?
answer: The committees have numerous projects underway aimed at addressing key challenges facing the statistical system.
child_questions: question: What can be fixed with the project information?
answer: However, mechanisms for disseminating information about their work are not comprehensive or up-to-date. Though member agencies are the most-likely customers of the committees’ products, making information about committee work and priorities more accessible could benefit other agencies, academics, and the general public. It could also benefit committee members by providing a central repository for information.

questions: question: What potential does admin data hold?
answer: Administrative data have greater potential to supplement rather than replace survey data.

question: What are the main ways these data are used?
answer: Agencies currently combine the two data sources in four key ways to cost-effectively increase efficiency and quality. Specifically, agencies use administrative data to: (1) link to survey data to create new data products; (2) supplement surveys’ sample frames; (3) compare to survey data to improve accuracy and design of surveys; and (4) combine with survey data to create, or model, estimates.

question: Why are there issues with expanding admin data use?
answer: However, expanding the use of administrative data faces key constraints related to the access and quality of the data. While agencies and committees are taking steps to address these constraints and facilitate the process through which agencies work together to share data, individual tools may not be sufficient.
child_questions: question: What could improve the potential problems?
answer: A more-comprehensive framework for use by all agencies involved in data-sharing decisions that includes key questions to consider when evaluating potential use of administrative data could make the decision process more consistent and transparent.

questions: question: What is the ACS?
answer: ACS, an ongoing monthly survey that provides information about the nation’s communities, offers agencies important opportunities to increase the efficiency and reduce the costs of their surveys, but its current design limits the extent to which agencies can utilize some of these opportunities.

question: What potential does ACS have?
answer: Uses that do not affect ACS design or the survey’s respondents, such as using ACS estimates to inform survey design or evaluate other surveys’ results, have widespread potential.
child_questions: question: What of this potential is limited?
answer: However, more-intensive uses, such as adding content or supplemental surveys to the ACS, currently have limited potential.

questions: question: Why must efficiencies be identified?
answer: As demand for more and better information increases, rising costs and other challenges require that the federal statistical system identify efficiencies.

question: What was the GAO asked to review surrounding cost-effectiveness?
answer: To explore opportunities to improve cost-effectiveness, GAO was asked to (1) review how the Office of Management and Budget (OMB) and agencies improve information collections, (2) evaluate opportunities and constraints for agencies to use administrative data (information collected as part of the administration of a program or held by private companies) with surveys, and (3) assess the benefits and constraints of surveys making greater use of the Census Bureau’s American Community Survey (ACS) data and resources.
child_questions: question: What did the GAO collect to make this review?
answer: GAO focused on collections administered to households and individuals, analyzed statutory and agency documents, did five case studies of surveys, reviewed documentation of representative samples of active surveys, and interviewed agency officials and experts.
