Rapidly growing cities faced a number of problems including but limited to:

1. Overcrowding: A huge influx of people from small cities, towns and villages resulted in cramped conditions.

2. Rising house prices/rents: It was a boom time for people who owned property. House prices and rents increased quickly.

3. Rising poverty and Ghettos: Most people who came to the cities were unskilled men with families and lots of children. This resulted in ghettos developing around the cities.

4. Rising Crime: All the above factors gave rise to a crime culture made up of young people looking to make some money and a 'name' for themselves.

5. Rise in disease: Poor living conditions resulted in constant outbreaks of chlorea and other water-borne diseases.
