Norway, a unitary state, is effectively divided into five regions, although this is for strategic geographical purposes only. The regions do not have their own administrative form of local government, nor a directly elected assembly. The regions are further divided into nineteen first-level administrative counties (fylker).

Does Norway have provinces or states?-Well, Norway doesn't have provinces or states like you might find in some other countries. Instead, it's divided into 18 administrative regions called counties. These counties have their own local governments and handle various matters within their areas. It's a different system from what we might be used to in the US. But that's how Norway organizes itself to manage things and provide services to its people. So, nope, no provinces or states in Norway!
