The population and housing census is part of an integrated national statistical system, which may include other censuses (for example, agriculture), surveys, registers and administrative files. It provides, at regular intervals, the benchmark for population count at national and local levels. For small geographical areas or sub-populations, it may represent the only source of information for certain social, demographic and economic characteristics. For many countries the census also provides a solid framework to develop sampling frames. This publication represents one of the pillars for data collection on the number and characteristics of the population of a country.
This publication provides an overview of census and survey data editing methodology. It reviews the advantages and disadvantages of manual and computer-assisted editing, and presents, in detail, procedures and techniques for editing census data at various stages of processing. Technical considerations, particularly those pertinent to programming, are covered in the annexes.
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.
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.
The usefulness of the U.S. decennial census depends critically on the accuracy with which individual people are counted in specific housing units, at precise geographic locations. The 2000 and other recent censuses have relied on a set of residence rules to craft instructions on the census questionnaire in order to guide respondents to identify their correct "usual residence." Determining the proper place to count such groups as college students, prisoners, and military personnel has always been complicated and controversial; major societal trends such as placement of children in shared custody arrangements and the prevalence of "snowbird" and "sunbird" populations who regularly move to favorable climates further make it difficult to specify ties to one household and one place. Once, Only Once, and in the Right Place reviews the evolution of current residence rules and the way residence concepts are presented to respondents. It proposes major changes to the basic approach of collecting residence information and suggests a program of research to improve the 2010 and future censuses.
