For the first iteration of the 1st district implemented under the 40 equal districts plan, the district once again encompassed all of Cape May and Cumberland counties. For the sessions following the
1980 census, the 1st included all of Cape May, but only included the Cumberland County cities of
Bridgeton, Millville, and Vineland, and the townships of
Deerfield, Maurice River, and
Upper Deerfield. The 1991 iteration of the 1st included all of Cape May, only Maurice River Township, Millville, and Vineland in Cumberland, and added
Buena and
Buena Vista Township in Atlantic County. With the exception of adding Atlantic County's
Somers Point, the 2001 iteration of the 1st remained the same as the 1991 district. The
2021 apportionment added Bridgeton, and removed Greenwich Township, Hopewell Township, Shiloh and Stow Creek Township. ==Election history==
