New Jersey v. Delaware Jurisdiction over rivers that form a border between states is usually determined by dividing the river down the middle between the states; this is not the case with the Delaware River. Delaware-New Jersey's curious border is the result of a grant by King Charles II in 1681, when the Delaware Colony was leased by William Penn from King Charles to become the three lower counties of Pennsylvania. The grant extended Delaware's northern border by The Twelve-Mile Circle in New Castle, Delaware, extending across the Delaware River. If the circle were to be extended fully, it would have included a portion of New Jersey, but this was unacceptable because that land had already been granted. As a result, the 12-Mile-Circle terminated at the mean low water mark on New Jersey's shore. The post-1681 border gave present-day Delaware full ownership of the Delaware River along a stretch of the New Jersey border.
Northeastern United States Using the Census Bureaus definition of the northeast, the region includes nine states: they are Maine, New York, New Jersey, Vermont, Massachusetts, Rhode Island, Connecticut, New Hampshire, and Pennsylvania.[1][a] The region is often subdivided into New England (the six states east of New York) and the Mid-Atlantic states (New York, New Jersey, and Pennsylvania). This definition has been essentially unchanged since 1880 and is widely used as a standard for data tabulation.[7][8][9][10] However, the Census Bureau has acknowledged the obvious limitations of this definition[11] and the potential merits of a proposal created after the 1950 census that would include changing regional boundaries to include Delaware, Maryland, and Washington, D.C. with the Mid-Atlantic states, but ultimately decided that "the new system did not win enough overall acceptance among data users to warrant adoption as an official new set of general-purpose State groupings. The previous development of many series of statistics, arranged and issued over long periods of time on the basis of the existing State groupings, favored the retention of the summary units of the current regions and divisions."[12] The Census Bureau confirmed in 1994 that it would continue to "review the components of the regions and divisions to ensure that they continue to represent the most useful combinations of States and State equivalents."[12]
