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.
