State, regional, and national estimates of health insurance coverage for people under 65 years of age: National Health Interview Survey, 2004-2006.
OBJECTIVE
This report presents state, regional, and national estimates of the percentages of persons under 65 years of age who were uninsured, who had private health insurance coverage, and who had Medicaid or State Children's Health Insurance Program (SCHIP) coverage.


METHODS
The estimates were derived from the Family Core component of the 2004-2006 National Health Interview Survey (NHIS). Three years of data were combined to increase the reliability of estimates. Regional and national estimates are based on data from all 50 states and the District of Columbia. State estimates are shown for the 41 states with at least 1000 NHIS respondents during 2004-2006. Differences between national and subnational estimates were tested for statistical significance to identify those regions and states that differ significantly from the U.S. overall.


RESULTS
The results show that the percentage of persons under age 65 who lacked any insurance coverage at a point in time varied by 20 percentage points among the states. Almost all states that were significantly higher than the U.S. rate on the percentage uninsured were significantly lower than the U.S. rate on the percentage with private coverage and vice versa.
