Spatial pattern of aid allocation in the early 21st century: Evidence from 38 sub-Saharan African countries

This study analyzes the geographical patterns of aid in 38 sub-Saharan African countries from 2001 to 2020, focusing on the extent of spatial exclusion in aid allocation at the regional level. By incorporating the Multidimensional Poverty Index (MPI) with aid expenditure data, we reveal that more impoverished regions, as defined by higher MPI scores, receive less aid compared to regions with high urbanicity. This pattern of exclusion shows significant spatial clusters within adjacent regions within and across countries and has persisted over the years. The allocation of sector-specific aid also exhibits a mistargeting issue. These findings emphasize the need to formulate aid strategies to promote spatial inclusivity in African countries.
