Summary[edit]

Description Global Population Count Grid Time Series Estimates provide a back-cast time series of population count grids based on SEDAC's Global Rural-Urban Mapping Project, Version 1 (GRUMPv1) data set. The grids were generated by using rates of population change between decades from the coarser resolution History Database of the Global Environment (HYDE) Version 3.1 to back-cast the GRUMPv1 population count grids. Mismatches between the spatial extent of the HYDE v3.1 calculated rates and GRUMPv1 population data were resolved by infilling rate cells based on a focal mean of values. The grids were then adjusted so that the population totals for each country equaled the UN World Population Prospects (2008 Revision) estimates for that country for the years 1970, 1980, 1990, and 2000.
