Criteria for Settlements (UN): Up to 1982: total population of cities and towns. Cities had to have a population of at least 100,000 or command special administrative, strategic, or economic importance to qualify as cit?ies. Towns were either settlements with more than 3,000 inhabitants of whom more than 70 per cent were registered as non-agricultural or settlements with a population ranging from 2,500 to 3,000 of whom more than 85 per cent were registered as non-agricultural. For the 1990 census: (1) all residents of urban districts in provincial and prefectural-level cities; (2) resident population of "streets" (jiadao) in county-level cities; (3) population of all residents' committees in towns. For 1996 and 2000: Not available. |

Population Edits and Notes: Population data were extrapolated to target years using a county (administrative level 3) growth rate calculated between the years 1990 and 2000. A 5% rate cap was applied to select units. The 2000 population data was missing for the administrative 3 level unit of Mangyadachaidan. A population growth rate was calculated using 1990 and 1995 Mangyadachaida population estimates. The 1995 data was then extrapolated to target years. |

Spatial Edits and Notes: "Taiwan was removed from the China shapefile.1990 and 1995 population estimates were added to GPW3 units from GPW2 as follows: 1) GPW2 polygons projected to match GPW3 coordinate system with slight adjustment in false northing to compensate for misalignment 2) Converted projected GPW2 polygons to centroids 3) Visually-inspected centroids to ensure placement within appropriate GPW3 polygon (verified by comparing to administrative unit names) and moved when necessary 4) Where disaggregation occurred, centroids were copied and pasted to corresponding empty polygons. 5) Performed spatial join in ArcMap to assign GPW2 attributes to the new polygons and assigned the sum of each population attribute if there were multiple centroids within each polygon 6) Inspected data to ensure no data loss 7) Data were converted to lat/long coordinates." |
