Data for: Downscaled gridded global dataset for Gross Domestic Product (GDP) per capita at purchasing power parity (PPP) over 1990-2022

PLEASE USE THE LATEST VERSION INSTEAD OF THIS ONE This dataset provides a gridded dataset for GDP per capita at purchasing power parity (PPP) downscaled to an admin 2 level (43,501 admin units). The dataset is based on reported subnational admin data (from 89 countries and 2,708 subnational units) and spans three decades from 1990 to 2022. The dataset is presented in details in the following publication. Please cite this paper when using data. Kummu, M., Kosonen, M. & Masoumzadeh Sayyar, S. 2025.
