How is it determined how many regions/provinces/states should be in a country?

Answer 1

Depends on how groups split up. There's no specific number that everyone thinks of, but as towns and locations grow and the place is not really a country yet, they elect leaders. Eventually there is unity in the country and the leaders specify boundaries that they can all agree on. If there's no unity, you'll have more than one country.

Answer 2

It's usually based on historical and traditional boundaries rather than having a preplanned number. Generally, a 'province' is whatever size or shape has proven convenient for whatever kind of governance is supposed to occur there. This tends to be adjusted with time based on population and government shifts, economic changes, and technological advances.

For example, not long ago Connecticut did away with county government because faster transportation and communication allowed the state to take over most of the functions of county government. In larger states, counties are still important units of government, and may serve functions that are performed elsewhere by state (e.g. road repairs) or local governments (e.g. dog licensing, school district). [If anyone cares: They take care of the roads because of greater geographic area, and the others because of lower population density.]

Eventually, the US may decide to split larger states (such as California and Texas) into smaller ones, and/or unite smaller states (such as the tiny New England states) into larger ones.

Answer 3

it is determined by the governing authority of that country, usually based on population, culture within a certain region, or natural barriers like rivers or mountain ranges. also, it is based upon annexaton. usa started with 13 and as we bought more land or took it over from the indians, we got new borders. thats how it works.
