You can check the local police dept for information. Here is a website about the neighborhood watch program in Manchester.
You can also acquire some demographic info about the town here:
I have represented both buyers and sellers in Manchester, including properties in adult communities and properties that were not located within an active adult community. As an agent, I had reason to interact with the township office in resolving issues for clients and found them helpful. You might try to contact them also.
If I can be of more help, please feel free to contact me.
