Statistical Yearbook 2021, Sixty-fourth Issue

The Statistical Yearbook provides a comprehensive compilation of internationally available statistics on social and economic conditions and activities, at world, regional and national levels, for an appropriate historical period. Most of the statistics presented in the Yearbook are extracted from more detailed, specialized databases prepared by the Statistics Division and by many other international statistical services. Thus, while the specialized databases concentrate on monitoring topics and trends in particular social and economic fields, the Statistical Yearbook tables aim to provide data for a more comprehensive, overall description of social and economic structures, conditions, changes and activities. The objective has been to collect, systematize, coordinate and present in a consistent way the most essential components of comparable statistical information which can give a broad picture of social and economic processes.
