National Academies Press: Measuring the Group Quarters Population in the American Community Survey: Interim Report

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.

Census Bureau Releases Alternative Income and Poverty Estimates

Latest News Release from the U.S. Census Bureau:

Census Bureau Releases Alternative Income and Poverty Estimates

The Census Bureau has released alternative income and poverty estimates covering calendar year 2009, including breakdowns by age, sex and race.

These estimates do not revise or replace the official 2009 income and poverty estimates released Sept. 16, 2010. The official estimate of the national poverty rate remains at 14.3 percent.

The Census Bureau has released alternative measures of poverty for many years based on the recommendations of Congress and the National Academy of Sciences. The purpose of these alternate measures is to show the effect on income and poverty measures when factoring in a range of poverty thresholds and different assumptions about income sources (such as subsidized housing or free or reduced-price school lunches).
