The American International Association for Economic and Social Development (AIA) (1946-1968), was established by Nelson A. Rockefeller in July 1946 as a privately financed non-profit philanthropic organization aimed to help promote "self-development and better standards of living, together with understanding and cooperation" in Latin America. The AIA worked closely with local governments and other established organizations to develop programs which could eventually be supported and managed locally. Primarily, the AIA's activities focused on rural rehabilitation and agricultural development, with concentrated efforts on cooperative programs with the governments of Brazil and Venezuela. The AIA was also active in agricultural research and nutritional education as well as improving local roads, communications, and primary education.

Subjects covered include local living conditions and customs, aspects of International Health Board/Division work, and scenic views.
