General Statistics on Deaf and HL Community
- On average, 3-5 newborns in 1000 are born deaf or with severe HL.
- Over 90% of deaf children are born to hearing parents.
- About 0.23% of all people are deaf: can’t hear or understand any speech.
- Up to 30% of kids between birth and age 3 have occasional ear infections.
- About 8% of kids aged 3 to pre-teen have occasional ear infections.
- Ear infections usually stop once the child has grown enough that their eustachian tubes are more downward sloped, around age 7 and up.
- Some people have chronic ear infections into adulthood.
- Yearly incidence of sudden deafness is 5 to 20 cases per 100,000 people.
- 15% of children between ages 6 to 19 have hearing loss in one or both ears.
- In people with sensorineural hearing loss, 5.4% develop the loss before age 3.
- In people with sensorineural hearing loss, 14.2% develop the loss between ages 3 to 19.
- About 14% of adults aged 45-64 have some type of hearing loss.
- About 33% of adults aged 65 and older have some type of hearing loss.
World Health Organization Data on Prevalence of Hearing Loss Globally
WHO definition of disabling hearing loss:
Children Age 0 to 14 years old = hearing thresholds >30 dB in one or both ears.
Adults Age 15 years or older = hearing thresholds >40 dB in one or both ears.
In 2012, WHO released new disabling hearing loss estimates based on 42 population-based studies:
- 360 million people or 5.3% of the world’s population have disabling hearing loss.
- 91% of these are adults aged 15 and older with disabling hearing loss.
- 9% of these are children aged 14 and younger with disabling hearing loss.
- 15% of people aged 15 to 64 have disabling hearing loss.
- 33% of people age 65 and older have disabling hearing loss.
- Males 56% have worse hearing than females 44%.
WHO compared disabling hearing loss by global regions and found:
3% = Middle East And North Africa
9% = Sub-Saharan Africa
9% = Central/East Europe and Central Asia
9% = Latin America and Caribbean
10% = Asia Pacific
11% = High Income (e.g. Canada, USA, UK)
22% = East Asia
27% = South Asia
Higher hearing loss prevalence in East and South Asia is likely related to poverty and poor healthcare, especially for children, and from noise damage in adults.
