The Departmentworks in three main interlinked areas: (i) it compiles, generates and analyses a wide range of economic,social and environmental data and information on which States Members of the United Nations draw toreview common problems and take stock of policy options; (ii) it facilitates the negotiations of MemberStates in many intergovernmental bodies on joint courses of action to address ongoing or emergingglobal challenges; and (iii) it advises interested Governments on the ways and means of translating policyframeworks developed in United Nations conferences and summits into programmes at the country leveland, through technical assistance, helps build national capacities. The Population Division of the Department of Economic and Social Affairs provides the internationalcommunity with timely and accessible population data and analysis of population trends and developmentoutcomes for all countries and areas of the world. To this end, the Division undertakes regular studies ofpopulation size and characteristics and of all three components of population change (fertility, mortalityand migration).
