Note. *, **, *** represent statistical significance at the 10, 5, and 1 percent levels in a two-sided t-test. Standard errors in parentheses do not take into account that the propensity score itself is estimated. Table entries are the difference in mean prevalence for each health outcome between those individuals who have been formerly incarcerated and those who have not. Parameters estimated using nearest neighbor inexact matching.
