In this research brief, we contribute to a much-needed, initial, and growing inventory of data on Puerto Rican migration after Hurricane Maria. Using data from the Federal Reserve Bank of New York/Equifax Consumer Credit Panel, we provide a detailed account of out-migration from and return migration to Puerto Rico in the quarters and years after Hurricane Maria. We show that out-migration from Puerto Rico was and remains elevated after Hurricane Maria, particularly for more vulnerable places with respect to water area and especially substandard housing. We also show that return migration to Puerto Rico by the second quarter of 2019 is low, 12–13%, with those emigrating from relatively more vulnerable places returning to the island at comparably higher levels than those from less vulnerable places. Taken together, our results help to round out a small, but growing body of research on migration after Hurricane Maria and other extreme weather events.

飓风玛丽亚之后从波多黎各迁出和返回波多黎各：来自消费者信贷小组的证据

在本研究简报中，我们为飓风玛丽亚之后波多黎各移民提供急需的、初始的和不断增长的数据清单做出了贡献。使用来自纽约联邦储备银行/Equifax 消费者信贷小组的数据，我们详细说明了在玛丽亚飓风过后的几个季度和几年内从波多黎各迁出和返回波多黎各的情况。我们表明，在飓风玛丽亚之后，来自波多黎各的外迁人数一直在上升，尤其是在水域面积和特别是不合标准的住房方面更脆弱的地方。我们还表明，到 2019 年第二季度，返回波多黎各的移民比例很低，为 12-13%，从相对较脆弱的地方移民返回该岛的人数比从较不脆弱的地方移民的人数要高。综合起来，
