DeafNetwork had these fascinating facts in its newsletter. I don’t know who deserves credit for putting this together, but it’s a neat read. The resources, however, appear at the bottom of the article.
At least 1 out of every 10 people (8.9% to be exact) in the USA has a hearing loss.
Generally speaking, it is estimated that at age 65, 1 out of every 4 people in the USA has some degree of hearing loss;
At age 75, 1 out of every 3 people in the USA has some degree of hearing loss;
At age 85, 1 out of every 2 people in the USA has some degree of hearing loss; and
At age 95, nearly everyone has at least some degree of hearing loss.
Hearing loss ranks equally with arthritis, high blood pressure, and heart disease as one of the most common physical ailments or conditions.
It is estimated that 30 school aged children per 1,000 have a hearing loss.
There are approximately 47,000 schools or programs for deaf and hard of hearing Americans.
Almost 80% of American deaf and hard of hearing school aged children are being educated in the public school system. A majority of these students use a combination of note takers, interpreters, amplification devices, or teachers with specific training.
Nearly 60% of all deaf students in America are taught through a combination of manual/ visual (sign language), aural (amplification) and oral (speech and lip reading) communication. Only 40% are taught through aural and/or oral communication only.
Though hearing loss may cause language delays for some children, it has no bearing on intellectual aptitude.
The biggest disabling factor for deaf and hard of hearing people are stereotypical attitudes.
A majority of deaf and hard of hearing people have difficulty speech reading as less than 20% of what is said can be clearly distinguished on the lips.
