Some of these include Groveville, Hamilton Square, Mercerville, White Horse, and Yardville. These are all places where many people live and work.
Other smaller communities and places within the township include Briar Manor, Broad Street Park, Bromley, and many more.

Economy and Growth
In recent years, Hamilton Township has seen a lot of new homes being built. Many of these new homes are for older adults, like retirement communities. This is happening for a few reasons.

Another reason for growth is the improvements to Robert Wood Johnson University Hospital, Hamilton. The hospital is now a highly respected place for medical care. It's located near undeveloped land, which is now being used for these new communities for older adults.
