Uninsured
Percentage of population ≤64 years without health insurance
Why do we measure the uninsured?
In 2016, 28.2 million Americans under age 65 lacked health insurance.People without health insurance may have limited access to health care, delay pursuing treatment, and experience poorer health compared to those with health insurance.2-4 Health insurance coverage increases preventive care use, such as breast and cervical cancer screenings and flu vaccinations.5 Health insurance coverage is also associated with increased labor force participation and higher incomes.3 Measuring the uninsured can also inform interventions aimed at increasing racial equity. Despite small gains in coverage, disparities persist in insurance coverage: People in lower income brackets are less likely than the general population to be insured.6-8
How do we measure the uninsured?
This metric includes persons, aged 0 through 64, who report having no current health insurance coverage.
Strengths and Limitations
Strengths of Metric | Limitations of Metric |
• Health insurance coverage is fundamental to being able to access quality healthcare. • Health care reform is currently a hotly debated political issue, and information about regional differences in health insurance coverage can help us understand how communities are affected. • This metric is available broken down by race and ethnicity, which can help target resources and interventions for groups that historically have been underrepresented. | • Insurance plans vary in what health care procedures and services they cover.9 • Individuals often move in and out of health insurance coverage, so a measure of current insurance status may not adequately represent the uninsured population.6 • Race and ethnicity data are often collected using discrete options that may not account for all or multiple identities, leading to undercounting of those who are more likely to select “other.” |
