Subnational socio-economic data are often difficult to obtain in low-income countries. Gross Domestic Product (GDP) data – and by extension, GDP per capita – do not exist for the 116 districts of Uganda, but there are many ways of constructing estimates with conceptual validity. This paper compares traditional regression-based approaches for estimation with geo-spatial models that use nighttime satellite imagery (from the Defense Meteorological Satellite Program-Operational Line Scanner, DMSP-OLS) and grid-based population density (from Landscan) to allocate Uganda’s national GDP to the district level. This paper also includes district-level data on agricultural production and the market value of associated crops to represent within country variations in agriculture’s contribution to GDP. We apply these methods to all countries in Africa to produce a spatially dis-aggregated map of GDP and GDP per capita at a spatial resolution of 1 km2.
