Greater Tehran Metropolitan Area is theurban agglomeration aroundTehran that covers the central part of theTehran Province and eastern part of theAlborz Province, that covers the contiguous cities of Tehran,Ray,Shemirānāt, and other areas.
As of 2012, Greater Tehran had a population of close to 14 million residents.[3] The 2016 census had the population at 13.3 million in Tehran Province (only 200 thousands of them outside Tehran and the suburban counties) and 2.2 million inKaraj andFardis combined. Therefore, it can be estimated that the population of the urban agglomeration was approximately 15 million people in 2016, and it is sinking at a rate of 25 cm per year due to the accelerated influx and overuse of natural resources.[4]
Since the 1960s, much of Greater Tehran's growth has been caused by an influx of urban poor into informal settlements on the fringe.[5]
Greater Tehran should not be confused with the following:
Tehran has three international airports: Mehrabad Airport, Imam Khomeini Airport, and Payam Airport. Mehrabad Airport is used for domestic flights, Imam Khomeini Airport is for international flights, and Payam Airport is for air cargo.[6]
There is no exact definition of Tehran agglomeration borders and composition. BesideTehran County, alsoShemiranat County,Ray County,Eslamshahr County,Pakdasht County,Robat-Karim County,Varamin County,Shahriar County,Qods County,Malard County,Pishva County, andBaharestan County in Tehran Province and alsoKaraj County and probably evenNazarabad County andSavojbolagh County inAlborz Province can be regarded as parts of the agglomeration.
