The population figures attached to the GIS database represent estimated totals for the standardized years 1960, 70, 80 and 90. Data sources vary by country. In general we attempted to obtain population data from each census that has been carried out at the geographical level for which boundary data were available.
Where official population estimates or projections were available from the national statistical office, these were used as well. In order to provide an indication of population dynamics and to maximize comparability across national boundaries, population estimates were produced for 1960, 70, 80, and 90.
