Let's say some government function is currently controlled on the local level. (For example, in the USA, most K-12 schools are controlled locally.)
If a federal government were to centralize control on the federal level, it would "federalize" that control.
If a federal government were to decentralize control on the local level, it would "localize" that control.
What is the equivalent for governments between "local" and "national", such as state governments in the USA?
- In Canada one might say "provincial control" and "provincialize control".
- In general, one might say "regional control" or "regionalize control" (though "regionalize" is more commonly used for "combining local agencies into one, below the state/province level").
- But "state control" implies public/government control (not private/firm control), while "statealize" is not a word.
Relevant previous questions: "Federal" is to "Federally" as "State" is to and "What's a word or phrase for something government-level or state-level?"
