Demographic Yearbook System
The United Nations Statistics Division collects, compiles and disseminates official demographic and social statistics on a wide range of topics. Data have been collected since 1948 through a set of questionnaires dispatched annually to over 230 national statistical offices and have been published in the Demographic Yearbook collection. The Demographic Yearbook disseminates statistics on population size and composition, births, deaths, marriage and divorce, as well as respective rates, on an annual basis. The Demographic Yearbook census datasets cover a wide range of additional topics including economic activity, educational attainment, household characteristics, housing characteristics, ethnicity, language, foreign-born and foreign population.

The technical reports review the instruments used by the Demographic Yearbook to collect data from national statistical offices in terms of how well they adhere to relevant international guidelines in terms of concepts, definitions and classifications used.
The technical reports also review the experience of countries with regard to reporting of the requested data to the Demographic Yearbook for the period 1961 to 2000, and relate national practices with respect to classifications to relevant international recommendations for the topics being reported. The main international recommendations that are the focus of the assessment are, as appropriate, the Principles and Recommendations for Population and Housing Censuses, Revision 1, the Principles and Recommendations for a Vital Statistics System, Revision 2, and Recommendations on Statistics of International Migration, Revision 1.
