For the 1981 redistricting, almost the entire district was changed, only retaining Red Bank from the previous map. It consisted of all of western Monmouth County and some boroughs of northeastern Monmouth including Tinton Falls, Rumson, and West Long Branch. In the 1991 redistricting, the total area of the district was reduced as the four panhandle municipalities of western Monmouth and some of the boroughs on the east side of the district were shifted to other districts. The district became a long, narrow district in an east–west fashion in the 2001 redistricting stretching from Oceanport through the central Monmouth townships, and continuing into East Windsor and Hightstown in Mercer County. Following the 2011 redistricting, the district boundaries experienced yet another major change when it became composed of municipalities from four counties, Burlington, Ocean, Monmouth, and Middlesex.
