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 14th District consisted of all of Passaic County. For the Senate, two members were elected at-large in the 1965 election for a two-year term, while three members were elected in 1967 for a four-year term and 1971 for a two-year term. The members elected to the Senate from this district are as follows:

For the members of the Assembly elected from Passaic County, the election method changed in every general election during this interim period. In 1967, two members were elected at-large from the entire county, while the county was split into three Assembly districts with one member elected from each district. Then in the 1969 election, one member was elected at-large and two Assembly districts in the county each elected two members. The election of 1971 reverted to the original 1967 method of electing Assembly members. The members elected to the Assembly from each district are as follows:
Session
District 14 At-large

District composition since 1973
When the 40-district legislative map was created in 1973, the 14th District originally included municipalities in western Morris County, all of Hunterdon County, New Jersey save for Readington Township, in Mercer County Ewing Township, Hopewell and Princeton townships and their enclosed boroughs, and Plainsboro and Cranbury townships in Middlesex. It took on a shape similar to its current configuration in 1981 when the 14th stretched from Hamilton, up eastern Mercer County, southwestern Middlesex, and Rocky Hill, Millstone, Manville, and Franklin Township in Somerset County. In the 1991 redistricting, the Somerset County portions of the district were removed but Monroe Township, Jamesburg, and Helmetta were added to the district. Washington Township, East Windsor, Hightstown, and Helmetta were removed from the district in the 2001 redistricting; the Hamilton Township-Middlesex County connection was made through West Windsor Township. East Windsor, Hightstown, and Robbinsville were restored to the district in the 2011 redistricting, West Windsor and South Brunswick were shifted to other districts, and Spotswood was added to the 14th for the first time.
