popgrids

This dataset consists 0.5 × 0.5 degree grids of:

1. Global population and GDP estimations for years 1980-2010 created by downscaling actual populations and GDPs by country, and
2. Global population and GDP projections for years 2020-2100 created by downscaling projected populations and GDPs under three shared socioeconomic pathways (SSP): SSP1; SSP2; and SSP3.

The dataset is modified Global dataset of gridded population and GDP scenarios, version 3. While the original dataset is a shapefile of 0.5 × 0.5 degree grids masked by countries, the new one contains a regular grid in form of raster objects.

Code used to create this data is at https://github.com/Nowosad/global_population_and_gdp.
