Data colonialism on the African continent has moved from abstraction into formal state policy through binding agreements signed without public consent, parliamentary scrutiny, or meaningful legal protection for citizens. Nigeria’s memorandum of understanding with France on tax administration data, alongside healthcare data-sharing agreements signed by Kenya and Rwanda with United States agencies, reflects a pattern of external control over sovereign information systems. These arrangements represent a transfer of strategic national assets rather than technical cooperation. Historical experience across former colonies shows that control over taxation, health records, and population data has always preceded deeper forms of domination, even when formal sovereignty remained intact.
