Input data set: Gross Domestic Product Per Capita (GDPpc) — Gridded (ISIMIP4)

Gross domestic product per capita in a grid cell, in US dollars in 2017 price level and 2017 Purchasing Power Parity, with annual timesteps.

Users should use this dataset rather than compute GDP per capita by dividing “Gross Domestic Product (GDP) — Gridded (ISIMIP4)” by “Population — Gridded (ISIMIP4)”, as the gridded total GDP is distributed partially by population and partially by land use.

This dataset was created in Horizon Europe project COMPASS (https://compass-climate.eu/) In a nutshell, the following process was used to derive the data:
(1) Historical (1850-2023) GDP per capita at national level (see “Gross Domestic Product Per Capita (GDP) — National (ISIMIP4)”) was compiled or estimated from many sources in COMPASS D3.1 [1] and further disaggregated by subnational GDP, where available, based on many sources collected in COMPASS. Future national GDP extended with SSP v3.2 [2].
(2) The value was distributed spatially according to country and country subdivisions masks developed in COMPASS D3.1 and defined at 30 arc second (~1 km) resolution. For coarser resolutions, the GDP per capita was weighted according to 30 arc second gridded population of each contributing country or country subdivision.
Gridded population was taken from “Population — Gridded (ISIMIP4)”. Input data, code and documentation (including detailed sources) is available on Zenodo [1] and will be further documented in a forthcoming journal publication.
