Quick Statistics


Men are more likely to experience hearing loss than women.
Of adults ages 65 and older in the United States, 12.3 percent of men and nearly 14 percent of women are affected by tinnitus. Tinnitus is identified more frequently in white individuals and the prevalence of tinnitus is almost twice as frequent in the South as in the Northeast.
Approximately 17 percent (36 million) of American adults report some degree of hearing loss.
There is a strong relationship between age and reported hearing loss: 18 percent of American adults 45-64 years old, 30 percent of adults 65-74 years old, and 47 percent of adults 75 years old or older have a hearing impairment.
About 2 to 3 out of every 1,000 children in the United States are born deaf or hard-of-hearing. Nine out of every 10 children who are born deaf are born to parents who can hear.
The NIDCD estimates that approximately 15 percent (26 million) of Americans between the ages of 20 and 69 have high frequency hearing loss due to exposure to loud sounds or noise at work or in leisure activities.
Only 1 out of 5 people who could benefit from a hearing aid actually wears one.
Three out of 4 children experience ear infection (otitis media) by the time they are 3 years old.
Roughly 25 million Americans have experienced tinnitus.
More than 112,000 people worldwide have received cochlear implants. In the United States, roughly 23,000 adults and 15,500 children have received them.
Approximately 4,000 new cases of sudden deafness occur each year in the United States. Hearing loss affects only 1 ear in 9 out of 10 people who experience sudden deafness. Only 10 to 15 percent of patients with sudden deafness know what caused their loss.
Approximately 615,000 individuals have been diagnosed with Ménière's disease in the United States. Another 45,500 are newly diagnosed each year.
Approximately 3 to 6 percent of all deaf children and perhaps another 3 to 6 percent of hard-of-hearing children have Usher syndrome. In developed countries such as the United States, about 4 babies in every 100,000 births have Usher syndrome.
One out of every 100,000 individuals per year develops an acoustic neurinoma (vestibular schwannoma).
