* 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 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.
