1911 Census of England and Wales, General Report with Appendices, Table 13: " Numbers, and Proportions per Million living, of Blind, Deaf and Dumb, and Mentally Deranged in the United Kingdom and in its several Divisions, at the Census of 1911 and at former Censuses".

NOTE.—The figures for the whole of the United Kingdom are available only from 1851 in the case of Blind and Deaf and Dumb, and from 1871 in the case of Mentally Deranged. The form of question in the schedule relative to infirmities has not been identical throughout the period shown in the table, nor in all Divisions of the Kingdom; exact comparisons are therefore not obtainable.
