Provides statistical information on the worldwide population of people 65 years old or older.

The Politics of Numbers is the first major study of the social and political forces behind the nation's statistics. In more than a dozen essays, its editors and authors look at the controversies and choices embodied in key decisions about how we count—in measuring the state of the economy, for example, or enumerating ethnic groups. They also examine the implications of an expanding system of official data collection, of new computer technology, and of the shift of information resources into the private sector. A Volume in the Russell Sage Foundation Census Series

This book is the first social history of the census from its origins to the present and has become the standard history of the population census in the United States. The second edition has been updated to trace census developments since 1980, including the undercount controversies, the arrival of the American Community Survey, and innovations of the digital age. Margo J. Anderson’s scholarly text effectively bridges the fields of history and public policy, demonstrating how the census both reflects the country’s extraordinary demographic character and constitutes an influential tool for policy making. Her book is essential reading for all those who use census data, historical or current, in their studies or work.

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.
