Tehran province (Persian: استان تهران, romanized: Ostān-e Tehrān) is one of the 31 provinces of Iran. Its capital is the city of Tehran, the national capital of Iran. Tehran Province covers an area of 18,814 square kilometres (7,264 sq mi) and is located to the north of the Central Plateau of Iran. It was made a part of the First Region with its secretariat located in Tehran, upon the division of the provinces into 5 regions, solely for coordination and development purposes on June 22, 2014. Tehran Province is situated in north-central Iran, lying on the southern slopes of the Alborz Mountains. The province’s location within the Alborz range gives it a diverse topography, with high mountains in the north and gradually descending plains toward the south. This geographical setting creates a varied climate, from cool alpine conditions to semi-arid lowlands. The province of Tehran has over 12 million inhabitants and is Iran's most densely populated region. Approximately 86.5 percent reside in urban areas and 13.5 percent in rural areas of the province.
