Administrative Population Edits and Notes:
The populations of Ardebil ostan (administrative level 1) and East Azerbaijan were aggregated. Also aggregated were the populations of Qom ostan and Tehran. The populations of Aliabad, Gonbad-e-Kavus, Gorgan, Kordkuy, Minudasht (onbad-e-Kavus), and Torkaman sharestans (administrative level 2) were assigned to the ostan Mazandaran (administrative level 1). 1986 population figures were not available at the shahrestan (administrative 2) level. Thus, population data were extrapolated to target years of 1990, 1995 and 2000 using growth rates calculated between 1986 and 1996 at the ostan (administrative 1) level. These rates were applied to the 1996 sharestans.
Administrative Spatial Edits and Notes:
In 1993, Ardabil ostan (administrative level 1) split from East Azarbaijan. In 1995, Qom ostan split from Tehran. In 1997, Aliabad, Gonbad-e-Kavus, Gorgan, Kordkuy, Minudasht (onbad-e-Kavus), and Torkaman sharestans (administrative level 2), all of which originally belonged to Mazandaran ostan, became a part of Golestan ostan.
