Notes:

Incidence rates are expressed per 1,000,000 population.

The incidence rate for the state of Idaho is age adjusted to the standard 1970 U.S. population using the direct method.

The incidence rates for the other geographic areas are the products of the standardized incidence ratios and the state age-adjusted rate.

Expected cases are based upon age and sex-specific rates for the state of Idaho (compare to observed).

P-Values compare observed and expected cases, are two tailed, based upon the Poisson probability distribution.

"<" denotes significantly fewer cases observed than expected, ">" denotes significantly more cases observed than expected (p=.05).

Statistical Note:

Rates based upon 10 or fewer cases (numerator) should be interpreted with caution.
