DATA SOURCE: Family Core component of the January-September 2001 National Health Interview Survey.

NOTES: The category public coverage includes Medicaid, Medicare (disability), State-sponsored or other government-sponsored health plan, and military health plan. The category private health insurance excludes plans that paid for only one type of service such as accidents or dental care. A small number of persons were covered by both private and public plans and are included in both categories. The analysis excluded persons with unknown health insurance status (about 1% of respondents). The data on type of coverage 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 having private or public coverage are generally within 0.1% of those based on manual editing procedures used for the final data files.
