Describe the various local government structures in the United States

Question

What will be an ideal response?

Answer 1

An ideal response would be:
In the United States, a county is a local level of government below the state. Counties are used in 48 of the 50 states; only Connecticut and Rhode Island are not organized by county. Delaware has the fewest counties (3), and Texas has the most (254). Sub-county governments include municipalities and townships, which are generally organized around population centers. Because the classification of population centers is a matter of state law, the definition of a city or town varies widely from state to state. However, most cities and towns have articles of incorporation—called charters—granted to them by the state. They are legally considered municipal corporations.
A large city that is a significant economic, political, and cultural center for the region is called a metropolis. This metropolis and its adjacent zone of influence, typically one or more closely neighboring cities, is considered a metropolitan area. Areas of high population density are considered urban; residential areas—typically within commuting distance of a city—are referred to as suburbs; and rural areas have low population density.
