Recent linkages between migration experiences, living arrangements and poverty are poorly understood for Puerto Rican-origin children. Despite very high poverty rates (58 percent for island-resident children and 32 percent for U.S.-resident Puerto Rican children), high levels of migration between the United States and Puerto Rico and high levels of single parenthood, Puerto Rican-origin children are often not the focus of research on children, families, poverty and migration (Mayol-García and Burd 2018). This research uses data on Puerto Rican-origin children (defined by detailed Hispanic origin data) ages 1-17 living in Puerto Rico and the United States to examine the ties among poverty, family migration and living arrangements. Family migration combines information on place of birth, residence one year ago and current place of residence. Logistic regression models predicting household poverty are run using American Community Survey and Puerto Rico Community Survey 5-year 2012-2016 estimates. The findings are evaluated regarding prior research.
