Table 1.1. Number and percent
of persons without health insurance coverage, by age group: United
States, 1997-2001
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 persons with unknown health insurance status (about 1% of respondents). The data on health insurance status were cleaned and edited using an automated system based on logic checks and keyword searches. For comparability, the estimates for all years were created using these same procedures. The resulting estimates of persons not having health insurance coverage are within 0.1 percentage point of those based on manual editing procedures used for the final data files. The number of uninsured was calculated as the percent of uninsured multiplied by the total population including persons with unknown coverage. The age-specific numbers of uninsured may not add to their respective totals due to rounding error. Age-adjusted estimates for persons under 65 years old (Healthy People 2010 leading health indicator) are based on a year 2000 standard population using three age groups: under than 18 years, 18-44 years, and 45-64 years. DATA SOURCE: Family Core component of the 1997-2001 National Health Interview Surveys. |
