A trailer park is a semi-permanent or permanent area for mobile homes or travel trailers. The main reasons for living in such trailer parks are the often lower cost compared to other housing, and the ability to move to a new area more quickly and easily, for example when changing jobs to another part of the country taking the mobile home/trailer with them. Ironically, this type of housing is very profitable for the manufacturers. Warren Buffett made a substantial portion of his fortune as the world's richest business man, by manufacturing trailer homes. Trailer parks, especially in American culture, are stereotypically viewed as lower income housing whose occupants live at or below the poverty line, have low social status and lead a desultory and deleterious lifestyle.
