Regional government index

Question: Are there elected regional governments, and --- if so --- to what extent can they operate without interference from unelected bodies at the regional level? Clarification: The lowest score would be reserved for a country that has no elected regional governments. A medium score would be accorded a country that has elected regional governments but where those governments are subordinate to unelected officials at the regional level perhaps appointed by a higher-level body. A high score would be accorded to a country in which regional governments are elected and able to operate without restrictions from unelected actors at the regional level with the exception of judicial bodies. Naturally, regional governments remain subordinate to the national government. Scale: Interval, from low to high (0-1).
