Abstract

This dataset provides a gridded subnational datasets for

Income inequality (Gini coefficient) at admin 1 level

Gross national income (GNI) per capita PPP at admin 1 level

The datasets are based on reported subnational admin data and spans three decades from 1990 to 2021.

The dataset is presented in details in the following publication. Please cite this paper when using data.

The following data is given (formats in brackets)

Income inequality (Gini coefficient) at admin 0 level (national) (GeoTIFF, gpkg, csv)

Income inequality (Gini coefficient) at admin 1 level (subnational) (GeoTIFF, gpkg, csv)

Gross national income (GNI) per capita PPP at admin 0 level (national) (GeoTIFF, gpkg, csv)

Gross national income (GNI) per capita PPP at admin 1 level (subnational) (GeoTIFF, gpkg, csv)

Slope for Gini coefficient at admin 1 level (GeoTIFF; slope is given also in gpk and csv files)

Slope for GNI per capita at admin 1 level (GeoTIFF; slope is given also in gpk and csv files)

Input data for the script that was used to generate the Gini coefficient (input_data_gini.zip)

Input data for the script that was used to generate the GNI per capita PPP (input_data_GNI.zip)

Files are named as followsFormat: raster data (GeoTIFF) starts with rast_*, polygon data (gpkg) with polyg_*, and tabulated with tabulated_*. Admin levels: adm0 for admin 0 level, adm1 for admin 1 levelProduct type:

_gini_disp_  for gini coefficient based on disposable income

_gni_perCapita_ for GNI per capita PPP
