I recently read Upton Sinclair's 'The Jungle.' There are several references to the 'ghetto district:'\
'The address Jurgis had was a garret room in the Ghetto district, the home of a pretty little French girl, Duane's mistress, who sewed all day, and eked out her living by prostitution.'\
'Ostrinski's home was in the Ghetto district, where he had two rooms in the basement of a tenement.'\
Where is or was this district? I think the definition of 'ghetto' has changed much since 1905. Also, the neighborhoods have probably changed much as well. Any ideas?
