Measuring The Group Quarters Population In The American Community Survey

Following several years of testing and evaluation, the American Community Survey (ACS) was launched in 2005 as a replacement for the census "long form," used to collect detailed social, economic, and housing data from a sample of the U.S. population as part of the decennial census. During the first year of the ACS implementation, the Census Bureau collected data only from households. In 2006 a sample of group quarters (GQs)-such as correctional facilities, nursing homes, and college dorms-was added to more closely mirror the design of the census long-form sample. The design of the ACS relies on monthly samples that are cumulated to produce multiyear estimates based on 1, 3, and 5 years of data. The data published by the Census Bureau for a geographic area depend on the area's size. The multiyear averaging approach enables the Census Bureau to produce estimates that are intended to be robust enough to release for small areas, such as the smallest governmental units and census block groups. However, the sparseness of the GQ representation in the monthly samples affects the quality of the estimates in many small areas that have large GQ populations relative to the total population. The Census Bureau asked the National Research Council to review and evaluate the statistical methods used for measuring the GQ population. This book presents recommendations addressing improvements in the sample design, sample allocation, weighting, and estimation procedures to assist the Census Bureau's work in the very near term, while further research is conducted to address the underlying question of the relative importance and costs of the GQ data collection in the context of the overall ACS design.

In the early 1990s, the Census Bureau proposed a program of continuous measurement as a possible alternative to the gathering of detailed social, economic, and housing data from a sample of the U.S. population as part of the decennial census. The American Community Survey (ACS) became a reality in 2005, and has included group quarters (GQ)-such places as correctional facilities for adults, student housing, nursing facilities, inpatient hospice facilities, and military barracks-since 2006, primarily to more closely replicate the design and data products of the census long-form sample. The decision to include group quarters in the ACS enables the Census Bureau to provide a comprehensive benchmark of the total U.S. population (not just those living in households). However, the fact that the ACS must rely on a sample of what is a small and very diverse population, combined with limited funding available for survey operations, makes the ACS GQ sampling, data collection, weighting, and estimation procedures more complex and the estimates more susceptible to problems stemming from these limitations. The concerns are magnified in small areas, particularly in terms of detrimental effects on the total population estimates produced for small areas. Small Populations, Large Effects provides an in-depth review of the statistical methodology for measuring the GQ population in the ACS. This report addresses difficulties associated with measuring the GQ population and the rationale for including GQs in the ACS. Considering user needs for ACS data and of operational feasibility and compatibility with the treatment of the household population in the ACS, the report recommends alternatives to the survey design and other methodological features that can make the ACS more useful for users of small-area data.

In June 2012, the Committee on National Statistics (sponsored by the U.S. Census Bureau) convened a Workshop on the Benefits (and Burdens) of the American Community Survey (ACS)-the detailed demographic and economic survey that began full-scale data collection in 2005 and that replaced the traditional "long form" in the 2010 census. ACS data are used by numerous federal agencies to administer programs, yet the ACS only moved from abstraction to reality for most users in 2010, when the first ACS estimates for small areas (based on 5 years of collected data) were made available. Hence, the workshop marked the opportunity to develop a picture of the breadth of the nonfederal user base of the ACS-among them, the media, policy research and evaluation groups (that distill ACS results for the media and broader public), state and local agencies, businesses and economic development organizations, and local and regional planning authorities-and to gather information on users' experiences with the first full releases of ACS products. In addition to covering innovative uses of the information now available on a continuous basis in the ACS, the workshop gave expression to the challenges and burdens associated with the survey: the time burden places on respondents, the challenges of explaining and interpreting estimates with increased levels of variability, and the privacy and confidentiality implications of some of the ACS content. Benefits, Burdens, and Prospects of the American Community Survey: Summary of a Workshop provides a factual summary of the workshop proceedings and hints at the contours of the ACS user constituency, providing important input to the ongoing review and refinement of the ACS program.

The Who, What, and Where of America Understanding the American Community Survey Part of Bernan Press's County and City Extra Series In the fall of 2013, the Census Bureau released data from the American Community Survey (ACS) one-year (2012) and three-year (2010–2012) estimates for the United States. The ACS replaced the decennial census long form in 2010 and now collects long-form-type information on a continuing basis rather than every 10 years, providing more current data. The ACS provides a regular stream of updated information for states and local areas and has revolutionized the way we use data to understand our communities. It produces social, housing, and economic characteristics for demographic groups. This fourth edition of The Who, What, and Where of America uses the 2010–2012 ACS data to present a concise resource of information that tells a story about America—its population, levels of education, types of employment and housing, and patterns of migration and transportation in one, convenient volume. The Who, What, and Where of America pulls details from the ACS that identify America at a certain point in time: Who: Age, Race and Ethnicity, and Household Structure What: Education, Employment, and Income Where: Migration, Housing, and Transportation Each part is preceded by highlights and ranking tables that show how areas diverge from the national norm. These research aids are invaluable for understanding data from the ACS and for highlighting what it tells us about who we are, what we do, and where we live. Each topic is divided into four tables revealing the results of the data collected from different types of geographic areas in the United States, generally with populations greater than 20,000. Table A. States Table B. Counties Table C. Metropolitan Areas Table D. Cities In this issue you will find social and economic estimates on the ways American Communities are changing with regard to the following: Age and race Health care coverage Marital history Education attainment Income and occupation Commute time to work Employment status Home values and monthly costs Veteran status Size of home or rental unit This title is the latest in the County and City Extra Series of publications from Bernan Press. Other titles include County and City Extra, County and City Extra: Special Decennial Census Edition, and Places, Towns, and Townships.

The National School Lunch and School Breakfast Programs, administered by the Food and Nutrition Service (FNS) of the U.S. Department of Agriculture (USDA), are key components of the nation's food security safety net, providing free or low-cost meals to millions of schoolchildren each day. To qualify their children each year for free or reduced-price meals, many families must submit applications that school officials distribute and review. To reduce this burden on families and schools and to encourage more children to partake of nutritious meals, USDA regulations allow school districts to operate their meals programs under special provisions that eliminate the application process and other administrative procedures in exchange for providing free meals to all students enrolled in one or more school in a district. FNS asked the National Academies' Committee on National Statistics and Food and Nutrition Board to convene a panel of experts to investigate the technical and operational feasibility of using data from the continuous American Community Survey (ACS) to estimate students eligible for free and reduced-price meals for schools and school districts. The ACS eligibility estimates would be used to develop "claiming percentages" that, if sufficiently accurate, would determine the USDA reimbursements to districts for schools that provided free meals to all students under a new special provision that eliminated the ongoing base-year requirements of current provisions. Using American Community Survey Data to Expand Access to the School Meals Program was conducted in two phases. It first issued an interim report (National Research Council, 2010), describing its planned approach for assessing the utility of ACS-based estimates for a special provision to expand access to free school meals. This report is the final phase which presents the panel's findings and recommendations.
