"Using data from the 1980 and 1990 5 percent [U.S.] Public Use Microdata Samples, I compare the settlement patterns and reasons for migration among foreign-born cohorts.... Although it is not possible to follow individuals over the two periods, aggregate changes in group location and migration patterns can be evaluated. Both period (differences associated with migration over time) and cohort (differences in migration behavior across arrival cohorts within a particular period) effects can be modeled. Of interest are the distribution, redistribution, and magnitude of change in the immigrant settlement system, along with why these adjustments occur for the 25 largest metropolitan areas in the United States. Results indicate that arrival cohorts of different vintages show contrasting responses to the determinants of settlement and migration behavior, although the overall distribution of the foreign-born population changed little over the two census periods."
利用1980年和1990年5%的[美国]公共使用微观数据样本，我比较了外国出生人群的定居模式和移民原因……虽然不可能在两个时期跟踪个人，但可以评估群体所在地和移民模式的总体变化。时期效应（与不同时间的移民相关的差异）和队列效应（特定时期内不同抵达队列的移民行为差异）都可以建模。感兴趣的是移民定居系统变化的分布、重新分布和变化幅度，以及美国25个最大都市区为何会出现这些调整。结果表明，不同年份的抵达队列对定居和移民行为的决定因素表现出不同的反应，尽管在两次人口普查期间外国出生人口的总体分布变化不大。
