A Population Commission was established by the Economic and Social Council in its resolution 3 (III) of 3 October 1946. In its resolution 49/128 of 19 December 1994, the General Assembly decided that the Commission should be renamed the Commission on Population and Development. In the same resolution, the Assembly decided that it, the Council and the Commission should constitute a three-tiered intergovernmental mechanism that would play the primary role in the follow-up to the implementation of the Programme of Action of the International Conference on Population and Development, and that the Commission, as a functional commission assisting the Council, would monitor, review and assess the implementation of the Programme of Action at the national, regional and international levels and advise the Council thereon.
