Tracking Intergenerational Progress for Immigrant Groups: The Problem of Ethnic Attrition
研究发现，追踪移民后代时，“族裔流失”（如美国出生的墨西哥裔不自我认同为墨西哥人）会导致测量偏差，且这种偏差在不同族裔群体中方向和大小各异，修正后多数西语裔移民后代的社会经济地位相对于亚裔会上升。
In tracking the later-generation descendants of immigrants, measurement biases can arise from “ethnic attrition” (e.g., US-born individuals who do not self-identify as Mexican despite having ancestors who immigrated from Mexico). We present evidence that such ethnic attrition is sizeable and selective for the third-generation populations of key Hispanic and Asian immigrant groups. In addition, our results suggest that ethnic attrition generates biases that vary across national origin groups in direction as well as magnitude, and that correcting for these biases will raise the socioeconomic standing of the US-born descendants of most Hispanic immigrants relative to their Asian counterparts.
