Which is bigger a country or a state?

Actually, none is always larger (in terms of area or population). In terms of area, take a look at the state of Alaska. If it were a country it would be the 17th largest nation. That means there would be 179 actual countries, so you cannot say a country is larger than a state. In terms of population, take a look at California. If it were a country it would be the 34th largest nation. This means there would be 162 actual countries that are less populated.
