About World Development Information Day
The General Assembly in 1972 established World Development Information Day to draw the attention of the world to development problems and the need to strengthen international cooperation to solve them.
The Assembly decided that the date for the Day should coincide with United Nations Day, 24 October, which was also the date of the adoption, in 1970, of the International Development Strategy for the Second United Nations Development Decade.
