Demographic Yearbook 2009-2010
Series: R, No.40
The Demographic Yearbook 2009-2010 is the sixty-first in a series published by the United Nations since 1948. It contains tables including a world summary of selected demographic statistics, statistics on the size, distribution and trends in national populations, fertility, foetal mortality, infant and maternal mortality, general mortality, nuptiality and divorce. Data are shown by urban/rural residence, as available. In addition, the volume provides Technical Notes, a synoptic table, a historical index and a listing of the issues of the Demographic Yearbook published to date.
The Demographic Yearbook 2009-2010 presents demographic statistics for two reference years: 2009 and 2010 in an effort to make it as up to date as possible. Consequently, for this issue the annual questionnaires were modified and extra worksheets were added, so that data for the latest two available reference years could be reported by the National Statistical Offices.
To accommodate the presentation of the statistics for two reference years, in population and vital statistics tables presenting time series, the available data for reference years 2009 and 2010 are presented side by side. As for the detailed population and vital statistics, two sets of tables, one referring to 2009 and the other referring to 2010, are displayed one after the other.
