Established by the Economic and Social Council (ECOSOC) of the United Nations (UN) in 1958 as one of the UN's five regional commissions, ECA's mandate is to promote the economic and social development of its member States, foster intra-regional integration, and promote international cooperation for Africa's development.

Made up of 54 member States, and playing a dual role as a regional arm of the UN and as a key component of the African institutional landscape, ECA is well positioned to make unique contributions to address the Continent’s development challenges.

ECA’s strength derives from its role as the only UN agency mandated to operate at the regional and subregional levels to harness resources and bring them to bear on Africa's priorities. To enhance its impact, ECA places a special focus on collecting up to date and original regional statistics in order to ground its policy research and advocacy on clear objective evidence; promoting policy consensus; providing meaningful capacity development; and providing advisory services in key thematic fields.
