The burden of unintentional drowning

Unintentional drowning mortality

In the Region of the Americas in 2021, unintentional drowning accounted for:

  • 1.6 deaths per 100,000 population (age-standardized), 2.7 deaths per 100,000 population in males and 0.6 deaths per 100,000 population in females.
  • Mortality from drowning was consistently higher in males than in females in most locations and over time.
  • The age-standardized death rates from unintentional drowning declined by 37% from 2.6 deaths per 100,000 in 2000 to 1.6 deaths per 100,000 in 2021.
  • From 2000 to 2021, age-standardized death rates due to unintentional drowning decreased in all subregions.
  • The Non-Latin Caribbean is the subregion with the highest level of mortality due to unintentional drowning. In 2021, its mortality was 2.23 deaths per 100,000 population, higher than that observed regionally.   

Age-standardized death rates due to unintentional drowning vary across countries from 9.9 deaths/100,000 population in Guyana to 0.4 deaths/100,000 population in Antigua and Barbuda.

Countries with the highest level of unintentional drowning mortality are:

  1. Guyana (9.9 deaths per 100,000 population)
  2. Hati (7.8)
  3. Bahamas (6.2)
  4. Saint Vincent and the Grenadines (4.9)
  5. Suriname (4.5)
  6. Belize (4.0)
  7. Saint Lucia (3.9)

DATA CLASSIFICATION

In the map and bar chart, data are presented in five discrete classes created using the quantile classification method. Each quintile class contains 20% of countries, which is easy to interpret. The quintile classes are labeled sequentially from Quintile 1 as the first quintile including the lowest fifth (0 to 20%) of the data to Quintile 5, the fifth quintile representing the class with the highest fifth (80% to 100%) of the data.

MEASURES

Measure names: Deaths, Disability-Adjusted Life Years (DALYs), Years Lived with Disability (YLDs), and Years of Life Lost (YLLs) due to diabetes mellitus

Metric: Rate 

Unit of Measure: deaths, DALY, YLD, and YLL per 100,000 population

Topic: Mortality and burden of disease

Rationale: Measuring how many people die each year and why they died is one of the most important means – along with gauging how diseases and injuries are affecting people's health – for assessing the effectiveness of a country’s health system. Statistics of causes of death help health authorities evaluate and focalize public health actions.

Disaggregation: Age, Sex, Country, and Year

Method of estimation: Mortality and burden of disease estimates by cause, age, sex, location (countries, and the region), and year were extracted from the WHO Global Health Estimates (GHE) 2000-2019. These estimates represent WHO's best estimates, computed using standard categories, definitions, and methods to ensure cross-country comparability, and may not be the same as official national estimates. 

Methodological details:

Data sources and methods for estimating causes of deaths and burden of diseases are described in the following documents. The cause list and corresponding IDC-10 codes are also included in these documents: 

Method of estimation of global and regional aggregates: Global, regional and subregional aggregates were computed by summing the absolute number of the measure (deaths, DALYs, YLDs, YLL) as the numerator and summing the population estimates from the World Population Prospect, produced by the UN Population Division, as denominators for all countries included in the geographic region or subregion. Rates were computed by dividing the aggregated numerator and aggregated population and multiplying the result y 100,000 population. Age-standardized rates were computed by the direct method using the World Standard Population. 

Preferred data sources: Civil registration and vital statistics (CRVS) system with complete coverage and medical certification of cause of death.
