The City of Orange is a township in Essex County, New Jersey, United States. As of the 2010 United States Census, the township's population was 30,134, reflecting a decline of 2,734 (-8.3%) from the 32,868 counted in the 2000 Census, which had in turn increased by 2,943 (+9.8%) from the 29,925 counted in the 1990 Census. 

Orange was originally incorporated as a township by an Act of the New Jersey Legislature on November 27, 1806, from portions of Newark Township. Portions of the township were taken on April 14, 1834, to form the now-defunct Clinton Township. On January 31, 1860, Orange was reincorporated as a town. Portions of the town were taken to form South Orange Township (April 1, 1861, now known as Maplewood), Fairmount (March 11, 1862, now part of West Orange), East Orange Township (March 4, 1863) and West Orange Township (April 10, 1863). On April 3, 1872, Orange was reincorporated as a city. In 1982, the name was changed to the "City of Orange Township" to take advantage of federal revenue sharing policies. Orange is often joined with neighboring East Orange, South Orange and West Orange and referred to as part of "the Oranges".http://en.wikipedia.org/wiki/Orange,_New_Jersey
