[533] 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. [534] The proportion of children generally out of school is found by the Russell Sage Foundation to average 21.8 per cent in all the states, ranging from 7.3 to 44.7 per cent. Comparative Study of Public School Systems in 48 States, 1912. [535] In respect to the ages most common in the schools for the deaf, it has been found by Dr. Harris Taylor, of the New York Institution for Improved Instruction, that of 2,634 pupils in 38 schools for whom returns were made, 19.8 per cent were seven years of age; 17.3 per cent, eight; 10.9 per cent, six; 10.2 per cent, nine; and 9.6 per cent, ten. Only 1.4 per cent were over nineteen. _Volta Review_, xiv., 1912, p. 177. [536] See Report of Western New York Institution, 1888, p. 28; Kentucky School, 1889, p. 14. In the regular schools 85 per cent of the pupils are said to drop out between the twelfth and fifteenth years. F. M. Leavitt, "Examples of Industrial Education", 1912, p. 54. See also Report on Condition of Women and Children Wage Earners in the United States, 1910, vol. 7. [537] In some cases it happens that the school is already crowded, but the need is no less, and it should be the business of the state to provide sufficient accommodations for all those who seek an education. [538] Great credit is often due to the schools for their efforts to get all the children in. Of the Kentucky School it is said that "there remain but few deaf children whom we have not seen personally". Report, 1907, p. 14. [539] We do not have sufficient data to enable us to make comparison between the attendance in states with a compulsory education law and those without it, though the former have in general apparently the better record. In Michigan it is stated that the compulsory education law has brought in many who otherwise would not have come. Report, 1908, p. 14.
