Haddon Township is a township in Camden County, New Jersey, United States. By an Act of the New Jersey Legislature on February 23, 1865, Haddon Township was incorporated from portions of Newton Township. The following communities were subsequently created from the Haddon Township: Haddonfield (April 6, 1875), Collingswood (May 22, 1888), Woodlynne (March 19, 1901), Haddon Heights (March 2, 1904), Audubon (March 13, 1905) and Oaklyn (also March 13, 1905). Haddon Township has two exclaves, West Collingswood Heights and West Collingswood Extension. The downtown portion of the township is known as Westmont, a name probably derived from a noted harness racing horse. Haddon Township allows sales of alcohols, and has several restaurants which serve alcohol, and bars, unlike the neighboring boroughs of Collingswood, Haddonfield and Haddon Heights which prohibit the sale of alcohol.
In 1701, Elizabeth Haddon Estaugh, the daughter of John Haddon, arrived in the American colonies to oversee his large landholdings, which included areas that are now Collingswood, Haddon Township, and Haddonfield. Contemporary Newton Township included land that later became part of Audubon, Audubon Park, Camden, Collingswood, Gloucester City, Haddon Heights, Haddonfield, Oaklyn, and Woodlynne. Its first European settlers were Irish who settled in the area of Newton Creek in 1681. In the late 1830s, a runaway slave, who had taken the surname Saddler to avoid detection by his former master, came to New Jersey from a Maryland plantation with his wife and two daughters. Saddler worked for Cy Evans, a local Quaker farmer, from whom he bought fifty acres to farm. The area where Saddler settled became a predominantly black community known as Saddlertown, a stop on the Underground Railroad. Today, Saddlertown is racially diverse.
The median income for a household in the township was $51,076, and the median income for a family was $65,269. Males had a median income of $44,943 versus $32,967 for females. The per capita income for the township was $25,610. About 1.6% of families and 4.1% of the population were below the poverty line, including 2.3% of those under age 18 and 5.2% of those age 65 or over.
