Data sources This database was initially produced for the UNEP/GRID-WRI-NCGIA Africa Population Database. See the GRID-Sioux Falls web site at http://grid2.cr.usgs.gov The 1980 and 1990 estimates produced for this database were used to produce the P95E estimate. Pop data sources: Republique Gabonaise (1980), Annuaire Statistique du Gabon 1976-80, Direction Generale de la Statistique et des Etudes Economiques, Ministere de la Planification de l'Economie et de l'Amenagement du Territoire, Libreville. Republique Gabonaise (1990), Annuaire Statistique du Gabon 1990, Direction Generale de la Statistique et des Etudes Economiques, Ministere de la Planification de l'Economie et de l'Amenagement du Territoire, Libreville. Republique Gabonaise (1993), Recensement Generale de la Population et de l'Habitat 1993, Resultats Preliminaires, Direction Generale de la Statistique et des Etudes Economiques, Ministere de la Planification de l'Economie et de l'Amenagement du Territoire, Libreville. Subnational and national pop figures for Gabon are very inconsistent. For example the national totals (as the sum of the first subnational level units) derived from different sources are as follows: 1970: 950,013 (Annuaire Statistique) 1976: 1,202,100 (Europa Yearbook) 1978: 1,299,000 (Statesmen's Yearbook) 1980: 1,035,610 (Annuaire Statistique) 1985: 1,170,980 (Annuaire Statistique) 1990: 1,365,400 (Annuaire Statistique) 1993: 1,014,997 (preliminary census results) The UN estimates for 60, 70, 80, and 90, are: 486000, 504000, 806000, 1146000. Similar inconsistencies are apparent in the subnational figures at the first level (available for all above listed years) and at the second level which were available only for 1980, 85, 90 (all estimates) and 1993 (prelim. census results). Consequently, the figures needed to be adjusted considerably and the resulting subnational estimates should be regarded as very rough estimates only!!!! Given that the national totals were very inconsistent, instead of using the raw figures, the final estimates are based on the proportion of a sub-units population of the national total. These proportions were then applied to the UN estimates for the four years. This was done for the 1980 and 1990 figures at the 2nd subnational level, and for 1970 at the first subnational level. For 1960, the same proportions as for 1970 had to be assumed since no additional information was available. This approach reduced the inconsistencies considerably, even though some strange numbers remain (e.g., districts loosing half their population in ten years). Map data source is the FAO coverage updated using IGN maps and information available from census publications.
