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.

Approximately 188,000 people worldwide have received cochlear implants. In the United States, roughly 41,500 adults and 25,500 children have received them.

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.
