It will be observed that three of the home counties occur in the first
four in the above list. It is interesting to note, in this connexion,
that the increase of population diminished steadily, in the three
decades under notice, within the area covered by the administrative
county of London, which is only the central part of urban London

This was 17.44% in 1871-1881, 10.39 in 1881-1891, and 7.3 in
1891-1901. This illustrates the constant tendency for the residential
