The United Nations Demographic Yearbook
system collects, compiles and disseminates official statistics
on a wide range of topics. Data have been collected from national
statistical authorities since 1948 through
a set of questionnaires dispatched
annually by the United Nations Statistics Division to over 230
national statistical offices.
The Demographic Yearbook disseminates
statistics on population size and composition, births, deaths,
marriage and divorce on an annual basis. These publications are
available for purchase
in printed format. The most recent
Demographic Yearbook is now available.
