Caldwell is a borough located in northwestern Essex County, New Jersey, about 16 miles (26 km) outside of New York. As of the 2010 United States Census, the borough population was 7,822.
Caldwell was incorporated as a borough by an Act of the New Jersey Legislature on February 10, 1892, from portions of Caldwell Township (now Fairfield Township), based on the results of a referendum held on the previous day. In 1981, the name was changed to the "Township of the Borough of Caldwell" to take advantage of federal revenue sharing policies. Effective January 26, 1995, it again became a borough.
Grover Cleveland, the 22nd and 24th President of the United States, and the only president to serve two non-consecutive terms, was born in Caldwell on March 18, 1837. His father, Rev. Richard Cleveland, was pastor of the First Presbyterian Church. The Grover Cleveland birthplace — the church's former rectory — is now a museum and is open to the public.
