Ghost town

A ghost town, deserted city, extinct town, or abandoned city is an abandoned or largely depopulated human settlement that usually contains substantial, visible remaining buildings and infrastructure, such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. mining has exhausted a local ore deposit). The town may also have declined because of natural or human-caused disasters such as floods, prolonged droughts, government actions, war, pollution, or nuclear and radiation-related accidents and incidents. The term can sometimes refer to cities, towns, and neighbourhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction.

The definition of a ghost town is debated amongst writers. Some restrict the term to places deserted for purely economic reasons, while others require visible remains of buildings, and still others allow for a small remaining population. Common causes of abandonment include the exhaustion of natural resources such as minerals or timber, the rerouting of railways or roads, dam construction that isolates or floods a town, armed conflict, forced displacement, and environmental contamination. Epidemics, including the Black Death and the Spanish flu, have also depopulated communities, as has long-term exposure to hazardous materials such as asbestos and lead.

Ghost towns are found on every continent, including Antarctica.
