Figure 1.2. Percent of persons aged under 65 years without
health insurance coverage, by age group and sex: United States,
January-June 2001

DATA SOURCE: Based on data collected from January-June 2001 in the Family Core component of the 2001 National Health Interview Survey.

NOTES: A person was defined as uninsured if he or she did not have any private health insurance, Medicaid, State-sponsored or other government-sponsored health plan, Medicare, or military plan at the time of the interview. A person was also defined as uninsured if he or she had only Indian Health Service coverage or had only a private plan that paid for one type of service such as accidents or dental care. The analysis excluded 573 persons with unknown health insurance status. The data on health insurance status were electronically cleaned or edited using logic checks and keyword searches. The resulting estimates of persons not having health insurance coverage are generally 0.1 percentage point lower than those based on the final data files.

For both sexes combined, the percent of persons uninsured was highest among persons aged 18-24 years (27.9%, 95% CI = 25.9% - 29.9%) and lowest among persons under 18 years (11.2%, 95% CI = 10.1% - 12.4%) and 45-64 years (12.2%, 95% CI = 11.2% - 13.2%). Younger adults were more likely than older adults to lack health insurance coverage.

For adults in age groups 18-24 years and 25-34 years, men were more likely than women to lack health insurance coverage.
