The servant-keeping classes, as I have described the groups that Mr. Booth has called Classes G and H, include everyone with an income of £150 a year and upwards, and, were statistics available, it might perhaps be shown that the unmarried women are, to a large extent, the daughters of clerks and professional men. The tradesman class do not find it nearly so difficult to provide for their sons and set them up in business as is the case in the salaried class; and it is an advantage from an industrial point of view for tradesmen to have wives who can help them in various ways. Emigration is probably more frequent in the salaried class; and where the sons are obliged to emigrate, it frequently happens that the daughters have to work for their living. In this class I believe the inequality of the sexes is greatest, and the probability of marriage least. In this class, therefore, the importance of an industrial training which shall enable women to earn a competency through all the active years of their life, which shall enable them to remain efficient workers and to provide for old age, is greater than in any other. As my object is not to point out how marriageable women may get married, but to show that a considerable number of women must remain unmarried, a table showing the inequality of numbers of the unmarried of both sexes in different districts in London is given. The districts are arranged in the order of poverty as calculated in 1889; the figures are from the Census of 1881. _Unmarried Women 35-45 to every 100 Unmarried Men 35-45._ Holborn 73 St. George’s-in-East 50 Bethnal Green 83 St. Saviour’s 81 St. Olave’s 75 Shoreditch 100 Whitechapel 36 Stepney 50 Greenwich 137 Poplar 50 Westminster 86 City 116 Islington 165 St. Pancras 135 Camberwell 200 Wandsworth 191 Marylebone 212 St Giles’ 86[4] Mile End Old Town 115 Lambeth 159 Woolwich 57[4] Fulham 200 Chelsea 143 Strand 66[4] Kensington 378 Hackney 230 St. George’s, Hanover Square 175[4] Lewisham 325 Hampstead 366 [4] The common lodging-houses in St. Giles’, the Woolwich Arsenal, the Inns of Court and hotels in the Strand, and the Knightsbridge Barracks in St. George’s, Hanover Square, may help to explain these exceptions to the rule.
