WHO recently published (March 2018) an update of the fact sheet Deafness and Hearing Loss, with the following Key Facts:

  • Around 466 million people worldwide have disabling hearing loss (1), and 34 million of these are children.
  • It is estimated that by 2050 over 900 million people will have disabling hearing loss.
  • Hearing loss may result from genetic causes, complications at birth, certain infectious diseases, chronic ear infections, the use of particular drugs, exposure to excessive noise, and ageing.
  • 60% of childhood hearing loss is due to preventable causes.
  • 1.1 billion young people (aged between 12–35 years) are at risk of hearing loss due to exposure to noise in recreational settings.
  • Unaddressed hearing loss poses an annual global cost of 750 billion international dollars (2). Interventions to prevent, identify and address hearing loss are cost-effective and can bring great benefit to individuals.
  • People with hearing loss benefit from early identification; use of hearing aids, cochlear implants and other assistive devices; captioning and sign language; and other forms of educational and social support.
