On April 3, 2008, the Sec. of Commerce announced significant changes to how the Census Bureau would conduct non-response follow-up, in which census workers interview households that do not return census forms for the 2010 decennial census, and to its Field Data Collection Automation (FDCA) contract. The Bureau has since issued a redesigned plan to conduct a paper-based follow-up operation, a 2010 Census project schedule, and is working on revising the FDCA contract. These are major changes late in the decennial census cycle. This testimony discusses: (1) the Bureau¿s plans for conducting a paper-based non-response follow-up operation; (2) mgmt. of the FDCA contract and its latest cost estimate; and (3) the status of the 2010 project schedule.

The Census Bureau has insufficient policies and procedures and inadequately trained staff for conducting high-quality cost estimation for the decennial census. Lacking plans for the development of both non-response follow-up and the management system, the Bureau faces the risk of not having them developed and fully tested in time for the 2010 Census. The Bureau faces long-standing challenges with the nation's linguistic diversity and privacy concerns, which can contribute to the under-counting of some groups. With just over a year remaining until Census Day, uncertainties surround the Bureau's overall readiness for 2010. Illustrations.
This open access book describes the differences in US census coverage, also referred to as “differential undercount”, by showing which groups have the highest net undercounts and which groups have the greatest undercount differentials, and discusses why such undercounts occur. In addition to focusing on measuring census coverage for several demographic characteristics, including age, gender, race, Hispanic origin status, and tenure, it also considers several of the main hard-to-count populations, such as immigrants, the homeless, the LBGT community, children in foster care, and the disabled. However, given the dearth of accurate undercount data for these groups, they are covered less comprehensively than those demographic groups for which there is reliable undercount data from the Census Bureau. This book is of interest to demographers, statisticians, survey methodologists, and all those interested in census coverage.
An accurate decennial census relies on finding and counting people -- only once -- in the right place and collecting complete and correct information. The author reviewed the Dept. of Commerce¿s U.S. Census Bureau¿s plans to: (1) improve the census¿s accuracy -- or coverage -- with its coverage follow-up operation; (2) assess the accuracy of the census through its census coverage measurement program; and (3) evaluate these efforts after 2010. Includes recommendations. Charts and tables.
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.
The census coverage measurement programs have historically addressed three primary objectives: (1) to inform users about the quality of the census counts; (2) to help identify sources of error to improve census taking, and (3) to provide alternative counts based on information from the coverage measurement program. In planning the 1990 and 2000 censuses, the main objective was to produce alternative counts based on the measurement of net coverage error. For the 2010 census coverage measurement program, the Census Bureau will deemphasize that goal, and is instead planning to focus on the second goal of improving census processes. This book, which details the findings of the National Research Council's Panel on Coverage Evaluation and Correlation Bias, strongly supports the Census Bureau's change in goal. However, the panel finds that the current plans for data collection, data analysis, and data products are still too oriented towards measurement of net coverage error to fully exploit this new focus. Although the Census Bureau has taken several important steps to revise data collection and analysis procedures and data products, this book recommends further steps to enhance the value of coverage measurement for the improvement of future census processes.
