註釋Population growth is centrally important to the process of regional development, but the role of population projection in regional planning has only recently begun to receive greater attention at the state and local levels. Regional planners have traditionally interpreted population projection to mean population prediction, and they have typically favored simple forecasting models which require relatively little time, expertise, money, and statistical information. This approach has served adequately a wide range of purposes, but the past several decades have witnessed a significant increase in the complexity of questions confronting state and local planners, and simple forecasting models no longer seem appropriate for all planning situations. The nature of regional planning warrants a further assessment of the role of population projection in planning activity. This paper addresses three major dimensions of the problem : (1) the selection of projection methods, (2) the design of projection systems, and (3) the definition of projection assumptions.
