QuickStats: Percentage of Uninsured Adults Who Did Not Have Health Coverage*, by Age Group and Type of Locality† — National Health Interview Survey, 2009–2011§

The figure shows the percentage of adults without health insurance, by age group and type of locality. The percentage of uninsured adults during 2009-2011 was lowest among those residing in large fringe metropolitan counties for both age groups (24.8% for adults aged 18-34 years and 13.3% for adults aged 35-64 years). The percentage uninsured in large fringe metropolitan counties was 12%-29% lower than in the other urbanization levels among adults aged 18-34 years and 22%-38% lower among adults aged 35-64 years. Among adults aged 18¬-34 years, the percentage uninsured was highest in the most rural counties. For all urbanization levels, the percentage uninsured was lower for adults aged 35-54 years than for younger adults.

* Health insurance coverage is at the time of the NHIS interview. Persons not covered by private insurance, Medicaid, Children's Health Insurance Program (CHIP), state-sponsored or other government-sponsored health plans, Medicare, or military plans are considered uninsured. Persons with only Indian Health Service coverage are considered uninsured.

Counties were classified into urbanization levels based on a classification scheme developed by NCHS that considers metropolitan–nonmetropolitan status, population, and other factors.

§ Estimates are based on household interviews of a sample of the civilian, noninstitutionalized U.S. population and are derived from the National Health Interview Survey family core and sample adult questionnaires.

95% confidence interval.

The percentage of uninsured adults in 2009–2011 was lowest (25% of adults aged 18–34 years and 13% of those aged 35–64 years) among those residing in large fringe metropolitan counties (suburbs of large cities). Among adults aged 18–34 years, the percentage uninsured was highest in the most rural counties (35%) and ranged from 28% to 31% in other urbanization levels. Among adults aged 35–64 years, 17%–18% in medium and small metropolitan areas and 20%–22% in large central metropolitan and nonmetropolitan counties lacked insurance. For all urbanization levels, the percentage uninsured was lower for adults aged 35–54 years than for younger adults.
