* Rates per 100,000 population. Beginning in 2021, single-race population estimates are used for rate calculations. For prior years, bridged-race population estimates are used. When comparing the 2021 rates by race/ethnicity to prior years, differences may be due to the change in the denominator and should be interpreted with caution (see Technical Notes).

Reported confirmed cases. For the case definition, see .

§ Numbers reported in each category may not add up to the total number of reported cases in a year due to cases with missing data.

Urbanicity was categorized according to the 2013 National Center for Health Statistics (NCHS) urban-rural classification scheme for counties and county-equivalent entities. Large central metro, large fringe metro, medium metro, and small metro counties were grouped as urban. Micropolitan and noncore counties were grouped as rural.

** US Department of Health and Human Services regions were categorized according to the grouping of states and US territories assigned under each of the 10 . For the purposes of this report, regions with US territories (Region 2 and Region 9) contain data from states only.

n/a: Not applicable. Rate cannot be calculated due to lack of corresponding denominator.
