Twelve-year trends in health insurance coverage among Latinos, by subgroup and immigration status

We examine twelve-year trends in the Latino uninsured population by ethnic subgroup and immigration status. From 1993 to 1999, most Latino subgroups, particularly Puerto Ricans, had large decreases in Medicaid coverage. For some subgroups these were offset by increases in employer coverage, but not for Mexicans, resulting in a four-percentage-point increase in their uninsured population. During 2000-2004, Medicaid/SCHIP expansions benefited most subgroups and mitigated smaller losses in employer coverage. However, during 1993-2004, the percentage of noncitizen Latinos lacking coverage increased by several percentage points. This was attributable to Medicaid losses during 1993-1999 and losses in employer coverage during 2000-2004.
