sentences:  For much of the 20th century, suburbs like Port Melbourne and Newtown (Sydney) were working class, low-income areas with a high proportion of migrants, sometimes regarded as slums.However, in the last quarter of the 20th century, suburbs like Paddington, Glebe and Newtown attracted many younger people because of their colourful character, the availability of cheap rental housing and their proximity to the city and major tertiary institutions like The University of Sydney.Many former students eventually settled in the area and bought property there, and these former "slums" soon became some sought-after locales, beginning a process of gentrification that saw many pub venues put under increasing pressure to modify their trading hours and limit the amount of noise that emanated from pub gigs, which was often considerable.
