Results based on an analysis of migration streams involving the metropolitan and nonmetropolitan sectors and covering a longer time interval than previously possible indicate that efforts to describe changes in the volume of movements connecting these sectors could benefit from greater attention to other related streams as well as existing patterns of population concentration. The metropolitanization process continues but is now being affected substantially by regional redistribution trends. Regional differentials in the size of metropolitan and nonmetropolitan migration streams are declining but are still substantial, so an equilibrium balance between the metropolitan and nonmetropolitan sectors will probably not occur in the immediate future.
基于对涉及大都市和非大都市地区的移民流分析得出的结果，且该分析涵盖的时间间隔比以往更长，结果表明，描述连接这些地区的人口流动量变化的努力，可能会因更多关注其他相关移民流以及现有的人口集中模式而受益。大都市化进程仍在继续，但目前正受到区域再分配趋势的重大影响。大都市和非大都市移民流规模的区域差异正在缩小，但仍然很大，因此在不久的将来，大都市和非大都市地区之间可能不会出现平衡状态。
