Watersheds of the World - Population Density
| Analytical Overview |
| A medium resolution global dataset, Gridded Population of the World (The Center for International Earth Science Information Network [CIESIN] 1995), was used to calculate population density. The dataset was compiled from the latest available census data at a variety of sub-national district levels, standardized to 1994. The total number of people in each basin was calculated using a 5-minute population count grid. Population density was calculated by dividing the total number of people in each watershed by the land area of each watershed. |
