Spatial clustering of vaccination coverage in DHS clusters. Using the Anselin Local Moran’s I, we classified each DHS cluster as being part of a spatial cluster with low-vaccination, high-vaccination, or mixed vaccination coverage (low-vaccination near high-vaccination or vice versa). Grey circles indicate that vaccination coverage for a DHS cluster was not statistically significantly clustered. a We detected clustering of low, mixed, and high vaccination coverage in all countries. Vaccination coverage in some spatial clusters contrasted nationwide vaccination coverage rates: e.g., b in the Zanzibar/Pemba islands and the Kenya-Tanzania border population (low vaccination vs. high nationwide); c in Northern Malawi (low vaccination vs. high nationwide); and (d) in the Madagascar capital region (high vaccination vs. low nationwide)
