A shanty town, squatter area, squatter settlement, or squatter camp is a settlement of improvised buildings known as shanties or shacks, typically made of materials such as mud and wood, or from cheap building materials such as corrugated iron sheets. A typical shanty town is squatted and, at least initially, lacks adequate infrastructure, including proper sanitation, safe water supply, electricity and street drainage. Over time, shanty towns may develop their infrastructure and even change into middle class neighbourhoods. They can be small informal settlements or they can house millions of people.
First used in North America to designate a shack, the term shanty is likely derived from French chantier (construction site and associated low-level workers' quarters), or alternatively from Scottish Gaelic sean (pronounced [ʃɛn]) meaning 'old' and taigh (pronounced [tʰɤj]) meaning 'house[hold]'.
