For the past 50 years, the Census Bureau has conducted experiments and evaluations with every decennial census involving field data collection during which alternatives to current census processes are assessed for a subset of the population. An "evaluation" is usually a post hoc analysis of data collected as part of the decennial census processing to determine whether individual steps in the census operated as expected. The 2010 Program for Evaluations and Experiments, known as CPEX, has enormous potential to reduce costs and increase effectiveness of the 2020 census by reducing the initial list of potential research topics from 52 to 6. The panel identified three priority experiments for inclusion in the 2010 census to assist 2020 census planning: (1) an experiment on the use of the Internet for data collection; (2) an experiment on the use of administrative records for various census purposes; and (3) an experiment (or set of experiments) on features of the census questionnaire. They also came up with 11 recommendations to improve efficiency and quality of data collection including allowing use of the Internet for data submission and including one or more alternate questionnaire experiments to examine things such as the representation of race and ethnicity.

Planning for the 2020 census is already beginning. This book from the National Research Council examines several aspects of census planning, including questionnaire design, address updating, non-response follow-up, coverage follow-up, de-duplication of housing units and residents, editing and imputation procedures, and several other census operations. This book recommends that the Census Bureau overhaul its approach to research and development. The report urges the Bureau to set cost and quality goals for the 2020 and future censuses, improving efficiency by taking advantage of new technologies.

From Book's Preface: Contains summary population totals for the United States, Puerto Rico, and the Island areas and for major race groups and an overview of political, statistical, and technological context in which the census took place. Describes preparations for the census, including lessons learned from the 1990 census, consultations with governmental and other data users, recommendations from the National Academy of Sciences and other advisory groups, and the plans for and results of census tests conducted between 1992 and 1998. Summarizes the history of each question on the short and long forms, the response categories, data uses, and any associated editing, allocation, and coding instructions. Reviews evaluations and recommendations from the 1990 program, the decision to use paid advertising in Census 2000, developing and implementing an integrated marketing strategy, components of the partnership program, and a series of special initiatives. Describes the organization and distribution of regional census centers and local census offices, the hiring and training of temporary field staff, the hardware and software used to track and assess census progress, and the different components of the enumeration process. Summarizes the decision to hire contractors to conduct data capture and manage the data capture centers, the hardware and software used to capture census data, the headquarters tabulation process, identification and deletion of duplicates, editing and imputation, intermediate data files, and the creation of the 100 percent and sample detail files. Covers such topics as data collection and tabulation geography, mapping, creating and updating the census address list, data products and their dissemination, the experimental and evaluation programs, legislation, litigation, the debate over sampling, and the census in Puerto Rico and the Island Areas.
