Populated places in Estonia (officially: settlement units[a]), are cities or settlement units of rural municipalities, but only cities have administrative functions. Settlement units are divided into settlements[b] and urban regions[c] (subdivisions of cities).
Officially there are four types of settlement units in Estonia:
- town/city (Estonian: linn)
- borough (Estonian: alev)
- small borough (Estonian: alevik)
- village (Estonian: küla)
