Marginal Groups in London were about 20,000 criminals who worried the police about law and order. The people who made a living by crime were in fact poor people who lived by stealing lead from roofs, food from shops, lumps of coal and clothes drying on hedges. There were others who were more skilled at their trade, experts at their jobs. They were cheats,tricksterts, pickpockets and petty thieves crowding the streets of London. Women were forced out of work from factories due to technological development they formed a large group that worked as domestic servants. They also worked at home to increase their income by taking in ladgers, working as tailors, wasting etc only during the war, they found jobs in factories and offices. Large number of children were forced into low-paid work. ‘‘A child of 7 could easily make 10 shillings led a week from thieving — a low-paid worker had to make 56 gross of match boxes a week to earn that much” (According to an article by Andrew Mearns). Only by the passage of Compulsory Elementary Education Act in 1870 and passing of Factory Acts (since 1872) children were kept out of industrial work. So, the marginal groups were the criminals, women are workforce and children forced to work in low-paid jobs.
