* County-level values represent the average of a range of likely values (defined here by 95% confidence intervals). State and national averages are compared to county-level values using these confidence intervals. 'Similar' indicates that the state or national averages fall within the county-level 95% confidence interval. 'Higher' indicates that state or national averages fall below the county-level 95% confidence interval.

  • 10-year trends are determined using linear regression. Percentages can be interpreted as the rate of change over the most recent decade. For example, +2.5% indicates a rate of increase of 2.5% per decade, and -2.5% indicates a 2.5% rate of decrease per decade. Trends that were not statistically significant (p>0.05) appear as 'no trend'.
