Abstract

A new methodological approach to the forecasting of short-term trends in internal migration in the United States is introduced. "Panel-data (or longitudinal-data) models are used to represent the relationship between destination-specific out-migration and several explanatory variables. The introduction of this methodology into the migration literature is possible because of some new and improved databases developed by the U.S. Bureau of the Census.... Data from the Bureau of Economic Analysis are used to investigate the incorporation of exogenous factors as variables in the model." The exogenous factors considered include employment and unemployment, income, population size of state, and distance between states. The author concludes that "when one...includes additional parameters that are estimable in longitudinal-data models, it turns out that there is little additional information in the exogenous factors that is useful for forecasting."

摘要

本文介绍了一种预测美国国内短期人口迁移趋势的新方法。“面板数据(或纵向数据)模型用于表示特定目的地的迁出与多个解释变量之间的关系。由于美国人口普查局开发了一些新的和改进的数据库,将这种方法引入迁移文献成为可能……经济分析局的数据用于研究将外部因素作为模型变量纳入其中。”所考虑的外部因素包括就业与失业、收入、州人口规模以及州与州之间的距离。作者得出结论:“当……在纵向数据模型中纳入可估计的其他参数时,结果表明外部因素中几乎没有对预测有用的额外信息。”
