Note. All models also adjust for age group, foreign born, and race / ethnicity. Post-graduate degrees include masters, doctorates, and professional degrees. Robust standard errors between parentheses. Sampling weights are applied. IRR = incidence-rate ratios, which are converted to a -1 to 1 range to reflect percent-effect sizes. P-values: *** <.001, **<.01, * = <.05 (two-tailed tests).
