Population and development in the United Nations system is under the responsibility of different intergovernmental bodies whose work is supported by the Secretariat of the United Nations and its affiliated agencies, programmes and funds. Within the United Nations work in the area of population is reviewed by a three-tiered system consisting of the General Assembly, the Economic and Social Council and the Commission on Population and Development.
Population and development issues in the United Nations system are treated by various entities. Among them are:
- United Nations Population Division in the Department of Economic and Social Affairs of the United Nations Secretariat (New York)
- United Nations regional commissions (Africa, Asia and the Pacific, Western Asia, Europe and Latin America and the Caribbean)
- United Nations Population Fund (UNFPA)
- United Nations specialised agencies, programmes and funds such as the World Health Organization (WHO), the United Nations Children's Fund (UNICEF) and the World Bank
