Which countries do not have cities? Which countries do not have villages?

Countries where there is not a single city simply do not exist. We have so-called city-states. For example, the Vatican is precisely a city-state. Of course, there are no villages here. Singapore is also a city-state, there are also no villages here. The area of this state is only seven hundred and twenty square kilometers. This state is about three and a half times smaller than Moscow. Almost six million people live here.
