Increase in the Number of the Deaf in Relation to the Increase in the General Population
ОглавлениеAre the deaf to be a permanent element in the constitution of the population? Are they always to be reckoned with in the life of the state and the regard of society? Would it not be well to inquire whether or not deafness may be eliminated, or at least reduced to an appreciable degree? These are questions that present themselves at the outset in a consideration of the relation of the deaf to society, and to them we now devote our attention.
Our first inquiry in the matter is directed to the question whether deafness as a whole is increasing, decreasing or remaining stationary, in relation to the general population. To determine this, we have recourse to the census returns of the deaf in connection with those of the general population. Unfortunately, however, comparisons of the different censuses respecting the deaf are not altogether to be depended upon, for the reason that they have not always been taken on the same basis, and conclusions from them consequently have to be accepted with qualifications. Special census returns of the deaf have been made since 1830; but the censuses of 1830–1870 purport to be of the deaf and dumb; the census of 1880, of the deaf who became deaf under sixteen years of age; that of 1890, of the deaf and dumb; that of 1900, of the totally deaf; and that of 1910, of the deaf and dumb. The results thus obtained are in the main analogous, but there are a certain number of cases included on one basis that would be excluded on another, and vice versa.[15]
Taking the statistics as they are, we have the following table,[16] which gives the number of the deaf as found in the several censuses, according to the bases upon which they were made, together with the ratio per million of population.
NUMBER OF THE DEAF ACCORDING TO THE CENSUSES OF 1830–1910
Year | Number | No. per Million of Population |
1830 (the deaf and dumb) | 6,106 | 475 |
1840 (the deaf and dumb) | 7,665 | 449 |
1850 (the deaf and dumb) | 9,803 | 423 |
1860 (the deaf and dumb) | 12,821 | 408 |
1870 (the deaf and dumb) | 16,205 | 420 |
1880 (deafness occurring under sixteen) | 33,878 | 675 |
1890 (the deaf and dumb) | 40,592 | 648 |
1900 (the totally deaf) | 37,426 | 492 |
1910 (the deaf and dumb) | 43,812 | 476 |
From this table there appears to be a steady decrease in the number of the deaf in relation to the general population from 1830 to 1860, this latter year seeming to be the low water mark. From 1860 to 1870 there is a slight increase, and from 1870 to 1880 a very large one, due to some extent to the method of taking the census. From 1880 to 1890 there is a certain decrease, though the proportion is still very high. From 1890 to 1900 there is a very considerable decrease, probably indicating a return to true conditions; and a not negligible decrease from 1900 to 1910.
On the whole, with respect to these statistics, probably the most that we can safely say is that deafness is at least not on the increase relatively among the population, while there is a possibility that at present it is decreasing. For further determinations, we shall have to seek other means of inquiry.
