Victorian Undreclass

The Victorian underclass was also known as the Submerged Class. It was made up of those people who were in poverty stricken areas including prostitutes and homeless people. The underclass was also made up of immigrants and refugees and “were much more susceptible to exploitation, and were therefore exploited.”(Victoria Web)
In 1888, Jack the Ripper preyed on members of the Victorian Underclass by murdering six prostitutes in the Whitechapel area of London. According to Wikipedia, there were 1,200 prostitutes "of very low class" resident in Whitechapel.
