ISLSCP II Global Population of the World
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.3334/ornldaac/975
Global Population of the World (GPW) translates census population data to a latitude-longitude grid so that population data may be used in cross-disciplinary studies.
Description
There are three data files with this data set for the reference years 1990 and 1995. Over 127,000 administrative units and population counts were collected and integrated from various sources to create the gridded data.
In brief, GPW was created using the following steps:

- Population data were estimated for the product reference years, 1990 and 1995, either by the data source or by interpolating or extrapolating the given estimates for other years.
- Additional population estimates were created by adjusting the source population data to match UN national population estimates for the reference years.
- Borders and coastlines of the spatial data were matched to the Digital Chart of the World where appropriate and lakes from the Digital Chart of the World were added.
- The resulting data were then transformed into grids of UN-adjusted and unadjusted population counts for the reference years.
- Grids containing the area of administrative boundary data in each cell (net of lakes) were created and used with the count grids to produce population densities. As with any global data set based on multiple data sources, the spatial and attribute precision of GPW is variable. The level of detail and accuracy, both in time and space, vary among the countries for which data were obtained.
