For example, global and national trends in population size are needed to project the future demand for food, water, and energy and the environmental impact of rising consumption of natural resources. Subnational projections help planners decide where to build new schools and where investments in roads and other infrastructure are required. Reliable estimates of the number of retired people in need of pensions and health care are essential to the optimal design of social security systems. Kajian editorial Population projections are the demographic outputs most used by nondemographers and most neglected by population scientists. Nondemographers may be surprised at the lack of a rigorous theoretical or even historical basis for the scenarios underlying the most commonly used projections. The task of making world projections—assessing the plausibility of current demographic estimates and choosing appropriate assumptions about future trends—are left by default to the small projection staffs of the United Nations Population Division, the World Bank, the U.S. Census Bureau, and similar agencies. These staffs, while qualified to do so, have neither the time nor the resources to conduct new research or fully evaluate current scientific work on the whole range of assumptions that undergird projections.
