Geography and Urban Evolution

Middlesex County features a diverse geographic layout, ranging from the dense urban corridors of New Brunswick and Perth Amboy to the sprawling residential areas of the south. The region has seen a significant shift in land use over the last few decades. Areas that were once considered exurbs—residential areas located beyond the suburbs—have transitioned into fully suburban environments.

Monroe Township serves as a prime example of this transition. Once a remote tip of the county, significant housing construction has transformed the area into a suburban hub.
