Burlington, Camden, and Gloucester counties have several older streetcar towns, and many residents commute to Philadelphia. The Courier-Post daily newspaper, which refers to itself as “South Jersey’s Newspaper” is based in Camden County. It covers all of South Jersey, but focuses primarily on these three counties. The South Jersey Times based in the city of Mullica Hill, however, is the principal newspaper for that county. Salem County and to lesser extents lower Gloucester County and upper Cumberland County serve as residential communities for the industries (mainly petro-chemical) in New Castle County, Delaware. The Atlantic shore areas, in particular Atlantic City in Atlantic County, New Jersey and Cape May have a distinct economy centered on tourism. Cape May has the distinction of being geographically as far south as Washington, D. C. , thus giving another sense to the name South Jersey.
