Global Population Density Grid Time Series Estimates
Listed in NASA Earthdata CMR
The Global Population Density Grid Time Series Estimates provide a back-cast time series of population density grids based on the year 2000 population grid from ESDIS' Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) data set.
Description
The grids were created by using rates of population change between decades from the coarser resolution History Database of the Global Environment (HYDE) database to back-cast the GRUMPv1 population density grids.
Mismatches between the spatial extent of the HYDE calculated rates and GRUMPv1 population data were resolved via infilling rate cells based on a focal mean of values. Finally, the grids were adjusted so that the population totals for each country equaled the UN World Population Prospects (2008 Revision) estimates for that country for the respective year (1970, 1980, 1990, and 2000). These data do not represent census observations for the years prior to 2000, and therefore can at best be thought of as estimations of the populations in given locations.

The population grids are consistent internally within the time series, but are not recommended for use in creating longer time series with any other population grids, including GRUMPv1, Gridded Population of the World, Version 4 (GPWv4), or non-ESDIS developed population grids. These population grids served as an input to ESDIS' Global Estimated Net Migration Grids by Decade: 1970-2000 data set.
