In Equateur Province, the Democratic Republic of the Congo (DRC), health workers had been told that communities along the Lokoro River were uninhabited — too prone to flooding, too hard to reach. GRID3 settlement data said otherwise, and in 2025, a team got in a boat. They found four villages where thirteen children received their first vaccine dose.

This was also the year GRID3 completed a six-year effort to map every province in the DRC. In Nigeria, 1.7 million fragmented settlement records were harmonised into a single dataset that health campaigns across 24 states can now plan against.

Our 2025 impact report documents what good data makes possible for communities that have spent years invisible to the systems designed to reach them.
