Another index of the condition of a people may be found in the way they are housed. Mean and comfortless dwellings imply not only a low standard of comfort, but often a low morality. Let us see how this matter has stood in Ireland. The Census Commissioners of 1841 divided the dwellings of the people into four classes. The fourth, or lowest, comprised all mud cabins having only one room. Of this class there were in all Ireland, according to the 1841 census, 491,278. In the last census, 1871, the number had fallen to 155,675. The third-class dwellings were also built of mud, but contained three or four rooms, with windows; the latter convenience being by no means universally present in the one-roomed cabin of the fourth class. Of the third class the census of 1841 enumerated 533,297; by 1871 this number had fallen to 357,126. The second class are described as good farmhouses, and in towns, houses having from five to nine rooms. Of this class in 1841 there were 264,184; and in 1871 the number had increased to 387,660. The first class of houses increased during the same period from 40,080 to 60,919. Let us see now in what way the population has been distributed in the different classes of houses. In 1841 the number of families occupying first-class houses was 31,333. In 1871 the number had risen to 49,693. During the same period the number of families in second-class houses rose from 241,664 to 357,752. On the other hand, the families in third-class houses decreased from 574,386 to 432,774; and those in the fourth-class, or one-roomed cabins, from 625,356 to 227,379. By a curious coincidence, the _proportion_ of families to houses was the same in 1841 and in 1871--one hundred and eleven families to one hundred houses. In this way the very great shifting in the _classes_ is all the more clearly proved to indicate a real rise in the condition of the people.
