* Per 100,000 population.

† Includes drowning deaths associated with boating incidents, a type of transportation injury death. The overall death rate excluding boating-related drowning was 1.17 per 100,000 population.

§ Persons identified as Hispanic might be of any race. Persons identified as white, black, or other race are all non-Hispanic. Nonfatal rates are not presented for racial/ethnic groups because race/ethnicity was unknown for a substantial percentage of persons with nonfatal injuries.

¶ Location of drowning by specific pool and natural water type is unavailable for mortality data. Rates are not presented for location because the denominator for each is the entire population.

** Nonfatal estimates might be unstable because the coefficient of variation is >30%, unweighted count <20, or 5-year weighted estimate <1,200.

* Distribution of nonfatal drownings are based on unweighted data for 604 National Electronic Injury Surveillance System – All Injury Program cases (342 cases in persons aged 0–4 years, 133 in persons aged 5–14 years, and 129 cases in persons aged ?15 years) and therefore are not nationally representative. Distribution for fatal drownings are based on 19,358 counted deaths.
