Political representation

The legislative district overlaps with New Jersey's 4th and 6th congressional districts.

1965–1973 In the interim period between the 1964 Supreme Court decision Reynolds v. Sims which required the creation of state legislature districts to be made as equal in population as possible and the 1973 creation of the 40-district map, the 13th district consisted of all of Bergen County. Senators were elected at-large from the entire county (four members in the 1965 election, five in the 1967 and 1971 elections) while the district was split into five Assembly districts that each elected two members.

The members elected to the Senate from this district are as follows: Session Senatorselected 1966–1967 4 Ned J. Parsekian (D) Matthew Feldman (D) Jeremiah F. O'Connor (D) Alfred Kiefer (D) 1968–1969 5 Fairleigh Dickinson Jr. (R) Joseph C. Woodcock (R) Alfred D. Schiaffo (R) Garrett W. Hagedorn (R) Willard B. Knowlton (R) 1970–1971 1972–1973 5 Harold C.

District composition since 1973 When the 40-district legislative map was created in 1973, the 13th district was located in the capital region of the state, only including Trenton and Hamilton Township in Mercer County. In the 1981 redistricting, the 13th was moved to encompass the northern Monmouth County shoreline (including Middletown Township, Hazlet, Matawan) and Old Bridge Township in Middlesex County. Following the 1991 redistricting, Matawan was removed but Spotswood in Middlesex County was added to the 13th. The district reverted to its 1981 configuration in 2001 with the exception of the addition of Holmdel. In the 2011 redistricting, the 13th district was located entirely in Monmouth County by removing Old Bridge and adding some of boroughs in the northeast corner of the county including Atlantic Highlands, Highlands, Monmouth Beach, and Oceanport. West Long Branch was added in 2023, while Fair Haven, New Jersey was shifted to the 11th legislative district.Symons, Michael.

Helen Chiarello Szabo took office in a November 1976 special election to succeed S. Howard Woodson, who resigned in September 1976 to head the New Jersey Civil Service Commission. In turn, Szabo stepped down in September 1978 to become the superintendent of elections in Mercer County and was succeeded in a November 1978 special election by Gerald R. Stockman.Mullin, Edward J. "The lone contest was hardly noticed", Herald News, November 12, 1978. Accessed December 15, 2022, via Newspapers.com. "Stockman, a Democrat, was elected over Republican Mario D. Rossetti to complete the unexpired term of Mrs. Helen Chiarello Szabo as General Assembly member for the 13th District. Mrs. Szabo had resigned from the Assembly to take her new job as Mercer County superintendent of elections. Stockman will complete her term and presumably will run for re-election to a full two-year term next year. The pattern was sequential. Mrs. Szabo, a journeyman or journeywoman Trenton politician, had come into the Assembly in a special 1976 election to fill the unexpired term of the Rev. S. Howard Woodson, formerly speaker of the House, had resigned to take a better political job as president of the State Civil Service Commission."
