As of the 2020 United States census, the city's population was 3,993, an increase of 69 (+1.8%) from the 2010 census count of 3,924, which in turn reflected a decline of 45 (−1.1%) from the 3,969 counted in the 2000 census.Bordentown is located at the confluence of the Delaware River, Blacks Creek, and Crosswicks Creek. The latter is the border between Burlington and Mercer counties. Bordentown is the northernmost municipality in New Jersey that is a part of the Philadelphia-Reading-Camden combined statistical area and the Delaware Valley. It is approximately one-third the distance between Center City, Philadelphia and Midtown Manhattan, located 5.8 miles (9.3 km) south of the state capital Trenton, 27 miles (43 km) northeast of Center City Philadelphia, and 54 miles (87 km) southwest of New York City.
Bordentown's first recorded European settlement was made in 1682 in what became known as Farnsworth's Landing and, after 1717, the town that had developed in the Provence of New Jersey was renamed to Borden's Town. Following the revolution and the establishment of the New Jersey state government, Bordentown was incorporated with a borough government form by an act of its legislature on December 9, 1825, from portions within Chesterfield Township. It was reincorporated with a city government form on April 3, 1867, and it was separated from Chesterfield Township about 1877.
