According to the census of 1900 there were 37,426 persons in the United States enumerated as totally deaf;[2] and according to that of 1910 there were 43,812 enumerated as "deaf and dumb."[3] Hence we may assume that there are between forty and fifty thousand deaf persons in the United States forming a special class.[4]

The following table will give the number of the deaf in the several states and the number per million of population, according to the census of 1910.[5]

From this table the largest proportions of the deaf appear to be found in the states rather toward the central part of the country, and the smallest in the states in the far west and the extreme east. The highest proportions occur in Kentucky, North Carolina, Utah, Indiana, West Virginia, Maryland, Tennessee, Missouri, Kansas, Virginia, New Mexico, Ohio, South Dakota, Wisconsin, Nebraska, New York, and Minnesota, all these states having over 500 per million of population. The lowest proportions are found in Wyoming, Arizona, New Jersey, Nevada, Florida, Delaware, Connecticut, Colorado, Montana, Washington, Massachusetts, California, District of Columbia, Idaho, Vermont, Oregon, Alabama, and Rhode Island, in none of these states the number being over 400 per million. Why there should be these differences in the respective proportions of the deaf in the population of the several states, we cannot say; and we are generally unable to determine to what the variations are to be ascribed—whether they are to be set down to particular conditions of morbidity, the intensity of congenital deafness, or other influences operating in different sections; or, perhaps in some measure, to the greater thoroughness with which the census was taken in some places than in others.
