There are 10 metropolitan areas in Romania that have been constituted as of 2013.
The current legislation in Romania regulates the status of the 265 cities according to their population and regional importance:
- Rank 0 – Bucharest, the capital of Romania - municipality of European importance
- Rank I – municipality of national importance, with regional role and potential influence at European level
- Rank II – municipality of national, regional or county-level importance, or with equilibrium role in the network of cities
- Rank III – cities
Legislation also restricts the possibility to engage into a metropolitan area project to only those cities that are of rank 0 or I. Here is a list of the municipalities that as of 2007 can for metropolitan areas around them with approximate populations. Only three zones have been officially constituted by the end of 2007: Oradea, Iasi and Constanta. At least 9 others are at the level of project.
