Overview

The global deaf population is roughly estimated to be 0.1% of the total population (1 in 1000).[1] The figure is likely to be higher in developing countries than developed countries due to restricted access to health care, and, in some cultures, due to the high rate of intrafamilial marriages. The great majority of people with less than average hearing are elderly or developed hearing loss after leaving school.[2] According to the U.S. National Center for Health statistics, approximately three quarters of deaf and hard-of-hearing Americans experienced the onset of hearing loss after age 18.[2]
