Administrative Population Edits and Notes:
District (administrative level 2) population data were missing for the following 9 provinces (administrative level 1): Ampara, Batticaloa, Colombo, Jaffna, Kilinochchi, Mannar, Mullaitivu, Trincomalee, Vavuniya. Hybrid administrative level 1 and 2 boundaries were created to account for these areas. A 1981?1991 province (administrative level 1) population growth rate was used to extrapolate population data to the target years of 1990, 1995, and 2000.
