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

Gross domestic product per capita at national level, with annual timesteps, in US dollars at 2017 price level, provided both at purchasing power parity (PPP, international dollars) and at market exchange rates (MER, US dollars).
Countries and other territories are identified by ISO 3166-1 code. Data is harmonized to a single delineation of boundaries reflecting actual present-day availability of statistical data.

This dataset was created in Horizon Europe project COMPASS (https://compass-climate.eu/)
Historical (1850-2023) GDP per capita at national level was compiled or estimated from many sources in COMPASS D3.1 [1]. Future national GDP per capita (2025-2100) was extrapolated from 2020 with gap-filled SSP v3.2 data [2], and 2024 interpolated between 2023 and 2025.
Input data, code and documentation (including detailed sources) is available on Zenodo [1] and will be further documented in a forthcoming journal publication.
In addition to the PPP series, gross domestic product per capita is provided converted at market exchange rates (MER) in 2017 US dollars.
