Catalonia is (as of 2018) divided into 947 municipalities. Each municipality typically represents one significant urban settlement, of any size from village to city, with its surrounding land. This is not always the case, though. Many municipalities have merged as a result of rural depopulation or simply for greater efficiency. Some large urban areas, for example Barcelona, consist of more than one municipality, each of which previously held a separate settlement. The Catalan government encourages mergers of very small municipalities; its "Report on the revision of Catalonia's territorial organisation model" (the ""), published in 2000 but not yet implemented, recommends many such mergers.
