This is an introduction to the services available through the Dynamic Data Base (DDB), set up in 1984 at the International Statistical Institute (ISI) in Voorburg, the Netherlands. The primary objective of the DDB is to promote policy-relevant analysis of demographic and related data. Although originally consisting of files containing survey data from 40 of the developing countries participating in the World Fertility Survey (WFS), its holdings have expanded so that by the end of 1986, the DDB held over 250 files relating to individuals, households, and communities from surveys in some 60 countries. The article includes information on holdings, documentation and archiving procedures, data access, software development and distribution, and analysis training.

This annual publication provides a catalog of machine-readable data files in the archives of the Inter-University Consortium for Political and Social Research (ICPSR). A section of the catalog gives information on census enumerations in machine-readable form. A section on the United States is divided into subsections on the historical and modern censuses, the Annual Housing Survey, the Current Population Survey, and other census files, including county and city data books. Files containing population data for countries other than the United States are listed in a separate section; it consists of files on Brazil, Canada, France, and the United Kingdom.
A section is also included on social institutions and behavior. Subsections on minorities, religion, youth, age and the life cycle, crime, leisure, and vital statistics are provided. The three vital statistics files listed all concern the United States.
