As on 1st March 2001, Indian population stands at 1,027,015,247 and projected population in 2016 will be 1, 263,543,000. (Census of India, 2001). With the present set of concept of hearing disability, the Census of India, 2001 counted 1,261,722 people in whom hearing disability exists (Males 53.4% and Females 46.59%). Majority of persons with hearing disability reside in rural India (81.06%) except in the Union territory of Chandigarh. Delhi, and Daman and Diu.
NSS 58th Round of Survey estimated persons with disability to be 18.49 million (1.8% of the total population). 10% of the persons with disability are likely to have hearing disability of moderate to profound degree. This number is likely to go high if we have to add hearing disability of lower degree.
