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: 1. United Republic of Tanzania (1969), 1967 Population Census. Vol. 1, Statistics for Enumeration Areas, Bureau of Statistics, Dar-Es- Salaam. 2. United Republic of Tanzania (1989), Statistical Abstract of Tanzania 1987, Bureau of Statistics, Dar-Es-Salaam. 3. United Republic of Tanzania (1989), Sensa 1988 - The 1988 Population Census, Preliminary Results, Bureau of Statistics, Ministry of Finance, Economic Affairs and Planning, Dar-Es-Salaam. District population figures were available for 1988 - from 3. and for 1967 fro 1. Where district boundaries changed and the changes could not be reconstructed, district figures were estimated assuming constant growth rates in the region; if it was clear which regions were split, proportional adjustment was used.1978 district totals: based on POP67 and growth rate 67-88. The resulting figures were uniformly adjusted to match the published region totals for 1978. P60-90 calculated by using the resulting intercensal growth rates for 66-78 and 78-88. Boundaries were produced by the International Center for Research in Agroforestry (ICRAF).
