New Jersey is a state on Earth, bordered on the north and northeast by New New York.
New Jersey can be thought of as five regions, based on natural geography and population. Northeastern New Jersey, the Gateway Region, lies within the New York City Metropolitan Area, and some residents commute into the city to work. Northwestern New Jersey, or the "Skylands", is, compared to the northeast, more wooded, rural, and mountainous. The "Shore", along the Atlantic Coast in the central-east and southeast, has its own natural, residential, and lifestyle characteristics owing to its location by the ocean. The Delaware Valley includes the southwestern counties of the state, which reside within the Philadelphia Metropolitan Area. The fifth region is the Pine Barrens in the interior of the southern part. Covered rather extensively by mixed pine and oak forest, it has a much lower population density than much of the rest of the state.
