GLAD Service Area
For over 43 years, GLAD has been improving the lives of the deaf and hard of hearing community proudly serving 10 counties throughout Southern California: Los Angeles, Kern, Orange, Ventura, Santa Barbara, Riverside, San Luis Obispo, San Bernardino, Inyo and Mono Counties.
With your support we can achieve even more by meeting the needs of newborns, children, teens, adults and senior citizens through additional programs that enhance the lives of deaf, hard of hearing and deaf-blind people everywhere.
Statistics & Population
According to the National Center for Health Statistics there are approximately 37 million deaf and hard of hearing people living in the United States. It is estimated that 1 in 10 live with some degree of hearing loss and over 2.2 million are considered deaf. The Office of Deaf Access estimates 3 million deaf and hard of hearing persons reside in California alone. Greater Los Angeles and surrounding counties is home to over 800,000 deaf and hard of hearing people.
The National Deaf Children’s Society states that 90% of deaf newborns are born to hearing families.
Statistics do not specifically establish any figures concerning any group in particular because of the way census forms are constituted. The United States is divided into states, counties and communities and data concerning logistics and population figures indicates all people with disabilities categorized as one group and unfortunately no distinction is made. *Figures are approximate
How a person identifies themselves in terms of their hearing loss is personal and may reflect identification with the deaf community or merely how their hearing loss affects their ability to communicate.

General Stats- US Statistics about Hearing Disorders and Deafness
National Institute on Deafness and Other Communication Disorders (2008)
Almost 12 percent of men who are 65 to 74 years of age 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.
Only 1 out of 5 people who could benefit from a hearing aid actually wears one.
About 2 to 3 out of every 1,000 children in the United States are born deaf or hard-of-hearing. 9 out of every 10 children who areborn deaf are born to parents who can hear.
Hearing loss affects approximately 17 in 1,000 children under age 18. Incidence increases with age: Approximately 314 in 1,000 people over age 65 have hearing loss and 40 to 50 percent of people 75 and older have a hearing loss.
Ten million Americans have suffered irreversible noise induced hearing loss, and 30 million more are exposed to dangerous noise levels each day.
Three out of 4 children experience ear infection (otitis media) by the time they are 3 years old.
At least 12 million Americans have tinnitus. Of these, at least 1 million experience it so severely that it interferes with their daily activities.
Approximately 59,000 people worldwide have received cochlear implants. About 250,000 people would be good candidates for a cochlear implant. In the United States, about 13,000 adults and nearly 10,000 children have cochlear implants.
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 Menieres disease in the U.S. 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.
Degree of Hearing Loss
Degree of hearing loss refers to the severity of the loss. The table below shows one of the more commonly used classification systems. The numbers are representative of the patient’s hearing loss range in decibels (dB HL).
|Degree of hearing loss||Hearing loss range (dB HL)|
|Normal||–10 to 15|
|Slight||16 to 25|
|Mild||26 to 40|
|Moderate||41 to 55|
|Moderately severe||56 to 70|
|Severe||71 to 90|
