A ghost town is a town that has been abanoned, usually because the economic activity that supported it has failed or because of natural or human-caused disasters such as war. The word is sometimes used in a deprecative sense to include areas where the current population is significantly less than it once was. It may be a partial ghost town such as Tonopah, Nevada or a neighborhood where people no longer live (like Love Canal). A tourist ghost town has significant economic activity from tourism, such as Oatman, Arizona, or numerous sites in Egypt, but cannot sustain itself except by tourism.
