* Rates for each period and for the full period were calculated using the following equation: (cases/population) x 100,000 persons. COVID–19 cases were identified using CDC’s Data Collation and Integration for Public Health Event Response system (https://data.cdc.gov/browse?tags=covid-19 [accessed January 27, 2021]). Case surveillance data were received directly from two jurisdictional health departments (Hawaii State Department of Health and New Mexico Department of Health) for all racial/ethnic groups to allow for separate reporting of NH/PI persons. Population estimates were provided by the 2019 U.S. Census Bureau’s Annual County Resident Population Estimates by Age, Sex, Race, and Hispanic Origin (https://www.census.gov/programs-surveys/popest/technical-documentation/file-layouts.html [accessed August 20, 2020]). 2019 population estimates in the 16 selected jurisdictions were as follows: persons aged <25 years: all (23,792,864), males (12,157,933), females (11,634,931), non-Hispanic AI/AN (329,235), non-Hispanic Asian (925,072), non-Hispanic Black or African-American (2,840,777), non-Hispanic NH/PI (83,012), non-Hispanic White (14,024,304), Hispanic or Latino (4,484,434), and non-Hispanic persons of multiple races (1,106,030); and persons aged 0–4 years (4,467,369), 5–9 years (4,622,261), 10–14 years (4,762,433), 15–19 years (4,855,127), and 20–24 years (5,085,674). No measures were calculated for non-Hispanic persons of other races with COVID-19 (n = 19,627) because of lack of population denominator information from U.S. Census Bureau.
