By definition, prevalence of presbycusis increases with advancing age.
No accurate account of the incidence of presbycusis in the United States is available. Approximately 25-30% of people aged 65-74 years are estimated to have impaired hearing. For people aged 75 years and older, this incidence is thought to rise to 40-50%.
The international incidence of presbycusis varies widely among societies. Westernized foreign countries and primitive civilizations have very different patterns of hearing loss.
No known difference exists in prevalence of presbycusis based on race.
