Global Population Distribution Database from UNEP/GRID-Sioux Falls
Listed in NASA Earthdata CMR
Population databases are forming the backbone of many important studies modelling the complex interactions between population growth and environmental degradation, predicting the effects of global climate change on humans, and assessing the risks of various hazards such as floods, air pollution and radiation.
Description
Detailed information on population size, growth and distribution (along with many other environmental parameters) is of fundamental importance to such efforts.
This database includes rural population distributions, population distrbution for cities and gridded global population distributions. This project has provided a population database depicting the worldwide distribution of population in a 1X1 latitude/longitude grid system. The database is unique, firstly, in that it makes use of the most recent data available (1990).

Secondly, it offers true apportionment for each grid cell that is, if a cell contains populations from two different countries, each is assigned a percentage of the grid cell area, rather than artificially assigning the whole cell to one or the other country (this is especially important for European countries). Thirdly, the database gives the percentage of a country's total population accounted for in each cell. So if a country's total in a given year around 1990 (1989 or 1991, for example) is known, then population in each cell can be calculated by using the percentage given in the database with the assumption that the growth rate in each cell of the country is the same.
And lastly, this dataset is easy to be updated for each country as new national population figures become available.
