In an effort to compare the burden of drowning in multiple countries, these authors used WHO databases to calculate mortality rates for unintentional drownings, and, if available, determine rates for various bodies of water.  To improve data collection and results, they combined data from the past 3 years and only reported countries with > 150 deaths for all age groups during that time.

The following is a summary of the interesting results:

  • Highest mortality rates for all ages (per 100,000)
    • Guayana (9.2)
    • Belarus (8.6)
    • Lithuania (8.5)
  • Highest mortality rates for ages 0-4
    • Kyrgyzstan (12)
    • Thailand (12)
    • Guayana (8.2)
  • Highest mortality rates for ages 65+
    • Japan (19)
    • Guayana (17.7)
    • Greece (10.5)
  • United States Statistics
    • All ages: 1.3
    • 0-4: 2.4
    • 65+: 1.5
  • UK Statistics
    • All ages: 0.4
    • 0-4: 0.4
    • 65+: 0.5
  • Australia Statistics
    • All ages: 1.1
    • 0-4: 2.1
    • 65+: 1.7
  • Of countries reporting high quality data for body of water (14)
    • Natural water was main body in 13
    • Bath tub was main body in Japan (mostly older adults, likely cardiac arrests)
    • Swimming pool deaths highest in US (18%) and Australia (13%)
    • US swimming pools
      • Majority of black victims drowned in public pools
      • Majority of white victims drowned in residential pools
      • Majority of hispanic victims drowned in neighborhood pools


As with any study looking at data of this nature, the authors found large variations in data quality between countries.  Unfortunately, countries like India and Bangladesh, both of which are known to have devastating mortality rates, had no WHO data available.
