  • —, rates and CIs were not calculated on unstable estimates.

  • a Some percentages do not total 100% because of rounding.

  • b Estimates are unstable because the coefficient of variation was >30%, the unweighted number of sample cases was <20, or the weighted estimate was <1200. Rates and CIs were not calculated on unstable estimates.
