Administrative Population Source Data:
The population figures for 1990 were based on the OECD/Club du Sahel West Africa Long Term Perspective Study (WALTPS), estimated by Benoit Ninnin from these sources: Republique Populaire du Congo, 1987, Annuaire Statistque, Ministere du Plan, Brazzaville [1974 data]; and Republique Populaire du Congo, 1987, Recensement General de la Population et de l''Habitat de 1984, Vol. 3: Resultats Definitifs, Tome I: Ensemble du Pays, Direction des Statistiques Demographiques et Sociales, Brazzaville.

Administrative Population Edits and Notes:
District level data were available for 1974, but only province level data could be obtained for 1984. Province level growth rates were originally used for interpolation, except for communes (6 major cities) for which data was available for 1974 and 1984, for Brazzaville and Pointe Noire also for 1960 from UNSTAT. These cities were treated explicitly, while the residual population in the corresponding district was interpolated using aggregate province growth rates. These data were used to estimate population in 1990 at the district level. Population data were extrapolated to the years 1995 and 2000 using regional growth rates between 1984 and 1996.
