Since 1970, metropolitan-to-nonmetropolitan migration has substantially exceeded the corresponding and historically greater stream of migrants from nonmetropolitan to metropolitan areas. Previous research has concentrated on the changes in retirement mobility, growth of recreation and tourism, and residential preferences responsible in part for the new trends in population distribution. Relatively less attention has been paid to the corresponding phenomenon of the deconcentration of persons who remain actively engaged in the labor force. This research uses data from the Continuous Work History Sample merged with a file of county characteristics to examine trends in location of employed workers from 1960 to 1975. The analyses document changes of county of employment that parallel the trends in general population mobility. The CWHS data show increased movement of employed workers out of the largest SMSAs and into the smaller SMSAs and into both adjacent and nonadjacent nonmetropolitan counties. These data also indicate that the rate of change is greatest for nonadjacent counties. Both increased metropolitan outmovement and decreased nonmetropolitan outmovement are significant in producing the observed net changes.
自1970年以来,从大都市区向非大都市区的人口迁移量已大幅超过了历史上规模更大的从非大都市区向大都市区的相应人口迁移流。此前的研究主要集中在退休人口流动的变化、休闲和旅游业的发展以及在一定程度上导致人口分布新趋势的居住偏好。相对而言,人们较少关注仍积极参与劳动力市场的人口分散化这一相应现象。本研究使用来自连续工作历史样本的数据,并与一份县特征文件相结合,以考察1960年至1975年就业工人的就业地点趋势。分析记录了就业县的变化,这些变化与总体人口流动趋势相似。连续工作历史样本数据显示,就业工人从最大的标准大都市统计区流出,流向较小的标准大都市统计区以及相邻和不相邻的非大都市县。这些数据还表明,不相邻县的变化率最大。大都市流出量的增加和非大都市流出量的减少在产生观察到的净变化方面都很显著。
