To what degree do immigrants reduce their high rates of residential overcrowding with increasing length of residence in the United States? This question is addressed through the application of a "double cohort" method that nests birth cohorts within immigration cohorts. This method enables duration of immigration effects to be separated from aging effects as cohorts pass through life course phases, when family sizes may be growing or shrinking. The analysis finds that cohort trends differ sharply from the cross-sectional pattern observed at a single point in time. Cohorts' growth in income is found to contribute substantially to the decline in overcrowding over time. Cohort trends among Hispanic immigrants, however, diverge from those among others, indicating much less decrease in overcrowding and even increases over certain age spans.
随着在美国居住时间的增加，移民在多大程度上降低了他们高比例的居住拥挤状况？这个问题通过应用一种“双重队列”方法来解决，该方法将出生队列嵌套在移民队列中。当队列经历生命历程阶段，家庭规模可能在扩大或缩小时，这种方法能够将移民效应的持续时间与年龄效应区分开来。分析发现，队列趋势与在某一时刻观察到的横截面模式有很大不同。随着时间的推移，队列收入的增长被发现对拥挤状况的下降有很大贡献。然而，西班牙裔移民的队列趋势与其他移民不同，表明在特定年龄跨度内，拥挤状况的减少要少得多，甚至有所增加。
