Jersey City lies on the west bank of the Hudson River across from Lower Manhattan in New York City (where about 26% of its employed residents work), and is part of the New York metropolitan area. A commercial and industrial center, it is a port of entry and a manufacturing center. With 11 miles (17.7 km) of waterfront and significant rail connections, Jersey City is an important transportation terminus and distribution center. It has railroad shops, oil refineries, warehouses, and plants that manufacture a diverse assortment of products, including chemicals, petroleum, electronics, textiles, and cosmetics. Jersey City has benefited from its location near the island of Manhattan, as many of its companies are extensions of businesses whose headquarters are there. Recent developments have included increased housing and shopping areas; some parts of the city, however, remain run-down after years of commercial inactivity.

Relations between ethnic groups in this heavily-mixed population are not always amicable, as evidenced by incidents such as the infamous Dotbusters gang attacks of 1987 against residents of South Asian descent, and, more recently, the March 2007 defacing of a local sports field with Nazi slogans and racial slurs.
Jersey City is ethnically diverse, with several distinct religious groups, prominently the Coptic Orthodox Church of Egypt. The large influx of Copts in New Jersey can be attributed to their persecution in Egypt, in addition to those who emigrate seeking education and financial opportunities. Currently, there are more than 30,000 Copts in Jersey City alone.
