  • Notes: Data from the 1998–2015 National Health Interview Survey. The sample includes children born in the United States in 1989–2005, observed at ages 6–16, whose parents are treated immigrants and whose mothers have a high school education or less. All regressions include state of birth and year of birth fixed effects. Treated immigrants defined as those born outside of the United States and who report arriving in the United States 1985–1996. The model includes controls for demographic characteristics (child’s age, gender, race/ethnicity, and number of siblings, as well as mother’s education, years lived in the United States, and age at childbirth) and controls for the state unemployment rate and Medicaid/SCHIP generosity at the time of birth and the time of the survey. The results are weighted using the NHIS-provided weights. Standard errors are clustered by state of birth and shown in parentheses. p-values for each estimate are shown in the second column, and the third column displays the p-values after adjustment for multiple hypothesis testing, described in more detail in the text. *p < 0.10, **p < 0.05, ***p < 0.01.
