| 説明 | Gridded Population of the World, Version 4 (GPWv4) Basic Demographic Characteristics, Revision 11 consists of estimates of human population by age and sex consistent with national censuses and population registers for the year 2010. Total Dependency Ratio (TDR) represents the total number of dependents relative to economically productive people and is a rough indicator of the socio-economic burden on the working population. TDR is calculated by dividing the sum of the children (ages 0–14) and elderly (ages 65+) rasters by the raster of working-age persons (ages 15–64) and multiplying the quotient by 100. These broad age group rasters were created by summing the 5-year age group rasters. |
