我们根据等效家庭收入来研究美国个人的流动性，也就是说，根据美国贫困线隐含的等效尺度，所有家庭成员的总收入根据家庭规模进行调整。我们的分析追踪了五分位数之间的变动，主要围绕四个问题展开：家庭收入分布中有多少变动？随着时间的推移，这种流动性是如何变化的？这些变动在多大程度上可归因于与家庭构成变化相关的因素，而不是劳动力市场的事件？鉴于在研究的四分之一世纪中发生的重大社会经济变化，流动性的决定因素是否随着时间的推移而改变？我们的研究结果表明，20世纪80年代的人口流动率与70年代相差不大。然而，在20世纪80年代，由年轻人或没有受过大学教育的家庭中的个人比20世纪70年代更不可能经历向上流动。
We examine the mobility of individuals in the United States based on equivalent family income-that is, total income of all family members adjusted for family size according to the equivalence scale implicit in the U.S. poverty line. Our analysis, which tracks movements across quintiles, centers on four questions: How much movement is there across the family income distribution? How has this mobility changed over time? To what extent are the movements attributable to factors related to changes in family composition versus events in the labor markets? In light of major socioeconomic changes occurring in the quarter-century under study, have the determinants of mobility changed over time? Our findings indicate that mobility rates in the 1980s differed little from those in the 1970s. However, individuals in families headed by a young person or a person without a college education were less likely to experience upward mobility in the 1980s than in the 1970s.
