Why do some town names followed by the word 'township'? Is this different than any other town?

Answer 1

The term township generally means the district or area associated with a town. However in some systems, especially in the U.S., no town need be involved, and indeed in the Scottish Highlands the term describes a very small agricultural community. Specific use of the term to describe political subdivisions has varied by country, usually to describe a local rural or semi-rural government within a county.
