Cochlear Implant Statistics

We are working on compiling information on the numbers of people who have a cochlear implant in the USA. International statistics are also welcome. Your help in bringing sources to us would be appreciated (email us at: aslciusers@gmail.com).

------------------------------------------------

According to the Gallaudet Annual Survey of school age children, approximately

37,500 children were surveyed in 2005.
only 4,000 were listed with cochlear implants.

This survey underestimates the numbers of children in the US with cochlear implants. We know that is not the case because of the manufacturer data.

------------------------------------------------

Manufacturer data:

As of 2007, approximately 120,000 individuals have cochlear implants worldwide according to the three cochlear implant manufacturers (Cochlear Corporation, Med El, and Advanced Bionics). There are at least 25,000 children under 18 who have obtained cochlear implants who are in the US. More than 1/2 of these students are reported to be under the age of 5.

Cochlear Corporation
91,000 individuals with their CI in the world
42,000 of those are children
48,300 of those are adults

In the USA:
35,500 in US
17,800 of those are children
21,700 of those are adults
Over 50% of the children being implanted are under 5 years old.

Advanced Bionics
24,000 with their CI in the world
55% of those are adults
45% of those are children
of that, 1,200 have bilateral cochlear implants
45% of adults have bilateral cochlear implants
55% of children have bilateral cochlear implants

Med El
we don't have their current statistics (if any of you know, let us know)

As of October 2005,
2,803 bilaterally implanted individuals by all three manufacters
1,638 were children

As of Fall 2006,
That number rose to 4,600

As of Fall 2007
That number rose to 6,000-7,000

At Kendall Demonstration Elementary School
1999: No children with cochlear implants
2007-2008: 26

At Model Secondary School for the Deaf
1999: One teenager with cochlear implant
2007-2008: 21

At Gallaudet University
2007-2008: 65 undergraduate students have a cochlear implant (representing 6 percent of all undergraduates)
24 of them being new students (representing 11% of the new students enrolled)

Special thanks to Gallaudet University Clerc Center's Cochlear Implant Education Center for the statistics. Click here to go to their website.

At Rochester Institute of Technology (RIT/NTID)
1999: 29 identified students and one faculty that have cochlear implants.
2007: 217 students have cochlear implant.

Although I do agree with your post, I have my own reservations.

I NEED TO FIND OUT IF THERE IS POST FOR SOMEONE WITH A SECOND CI THAT DID NOT SET UP OR DOES NOT OPERATE. I KNOW THAT THE DOCTOR THAT PERFORMED THE SURGERY ON THE FIRST ONE WAS AWARE OF THAT AND THAT IS WHY HE DID THE RT SIDE FIRST. OF COURSE KNOW HE HAS RETIRED. A NEW DOCTOR IS LOOKING INTO THE COCLEAR,WHICH IS NOT OPERATING. I HEAR LOW TONE NOICES AND I DON'T THINK THAT IT CAME FROM THE OTHER SIDE. SHOULD THIS BE LOOKED AT OR MAYBE A WHOLE NEW SURGERY DONE. THANK YOU TC.
