Note 533 — Chapter XVIII

It has been found that, by comparing the number of the deaf in school in the several states with the total population of 1910, the best record is 26.0 per 100,000 of population, which belongs to Wisconsin; and if this ratio be accepted as an approximate standard, the average proportion for all the United States is only one-half, with a ratio of 13.6 per 100,000, while in a few of the states it is only one-third, the lowest ratio being 6.1 per 100,000. If all the states had as high a ratio as 26, the number in attendance would be 23,913. The finding of these results is due to Mr. F. W. Booth, Volta Review, xii., 1911, p. 786. If we compare the number of the deaf reported by the census under twenty years of age with the number found at school. In 1912-1913, the lowest proportion is seen to be 45 per cent, though only half a dozen states have proportions under 60.
