A pit village is a term used in parts of the UK for the village serving a deep coal mine.
In these villages many of the workers lived in houses that were provided by the colliery. Many villages have experienced depopulation after colliery closures in the 1980s forced people to move to other towns and cities where there are jobs for them to make a living. This has been more prevalent in remote areas; by contrast some pit villages that border cities, in particularly Leeds and Newcastle upon Tyne, have experienced population growth after colliery closures.
