Though Monroe is not officially broken down into traditional neighborhoods but over the years residents have given names to various parts of the township. Three common names heard in the township are Mill Lake Manor (an area centered on Monmouth Road and 10th Avenue) and Outcalt (in thenorthern part of the township, near Spotswood and Helmetta). For those who have lived in Mill Lake Manor, the area is broken down further into the "Old" and "New" Manor (split by Monmouth Road on the east and west sides, the Old being east and the New being the west side). The Manor also encompasses the developments of Inwood. The neighborhood east of Spotswood-Englishtown Road, centered on Monmouth Road, extending down to 1st Avenue, is called North Manor or Manor Heights.
