Twelve million people, in relief.
Each column represents the population of a roughly 5 km cell, estimated by WorldPop from censuses, satellite imagery and building footprints. 3D makes human geography instantly readable: coastal concentration around Cotonou, urban strings along corridors, the emptiness of protected areas.

From estimate to sizing
Estimation
WorldPop disaggregates national censuses using satellite imagery and building footprints, producing a consistent, dated kilometre-scale population grid.
Visualisation
Each column's height is proportional to inhabitants: urban hierarchies, corridors and territorial imbalances are visible without a single table.
Sizing
Power and telecom networks, branches, schools, water points: OHM WORKS crosses these densities with your field data to size supply and prioritise investment.
Coverage analyses for your areas?
Operators, developers, institutions: we produce tailored population-coverage analyses — catchment areas, network coverage, accessibility — grounded in Beninese data. Let's talk.
