[17] Before its merger with the adjacent Borough of Pine Hill, Pine Valley was the third-smallest municipality by population in New Jersey, with 12 more residents than the nine residing in Tavistock (also in Camden County) and 14 more than the seven in Walpack Township (in Sussex County).

Pine Hill gained $20 million in taxable property and the famed golf club.

[21][22][23] The 2010 United States census counted 12 people, 4 households, and 4 families in the borough.

[29] As of the 2000 United States census[12] there were 20 people, 8 households, and 7 families residing in the borough.

[27][28] Pine Valley operated under the Walsh Act form of New Jersey municipal government.

[35][36] The three incumbents—Jane Bromley and husband-and-wife Michael B. Kennedy and Deborah Kennedy—were re-elected in May 2014 to four-year terms of office in an election held entirely by mail to minimize the costs associated with establishing a polling place for the borough's 14 voters.

[39][40][41] Prior to the 2011 reapportionment following the 2010 census, Pine Valley had been in the 6th state legislative district.

[42] For the 119th United States Congress, New Jersey's 1st congressional district is represented by Donald Norcross (D, Camden).

[45] For the 2024-2025 session, the 8th legislative district of the New Jersey Legislature is represented in the New Jersey Senate by Latham Tiver (R, Southampton Township) and in the General Assembly by Andrea Katz (D, Chesterfield Township) and Michael Torrissi (R, Hammonton).

At a reorganization meeting held in January after each election, the newly constituted Board of Commissioners selects one member to serve as Director and another as Deputy Director, each serving a one-year term in that role.

[54][47][55][56][57] Camden County's constitutional officers are: Clerk Pamela Rosen Lampitt (D, Cherry Hill, 2029)[58][59] Sheriff Chuck Billingham (D, Gloucester City, 2027)[60][61] and Surrogate Michelle Gentek-Mayer (D, Gloucester Township, 2025).

[65] In the 2013 gubernatorial election, Republican Chris Christie received 100.0% of the vote (nine cast), ahead of Democrat Barbara Buono and other candidates who received no votes, among the nine ballots cast by the borough's thirteen registered voters, for a turnout of 69.2%.

[70] At that time, public school students from Pine Valley attended the Haddonfield Public Schools for pre-kindergarten through twelfth grade as part of a sending/receiving relationship, together with students from Haddonfield and Tavistock.
