The Centre for Social Development and Humanitarian Affairs (CSDHA) was the division of the Economic and Social Council of the United Nations (ECOSOC), responsible for coordination of all issues related to social policy within the United Nations system. It was based at the UN Office in Vienna, Austria (UNOV) until the 1990s. It moved to the United Nations Headquarters in New York and is now known as the Division for Social Policy and Development.[1][2]
