Hanoi metropolitan area

This metropolitan area was created by Decision 490/QD-TTg dated May 5, 2008, of the Prime Minister of Vietnam. Hanoi will be the core city of this metropolitan area. Other parts will include provinces: Vĩnh Phúc Province, Hưng Yên Province, Bắc Ninh Province, Hải Dương Province, Hà Nam Province, Hòa Bình, Bắc Giang Province, Phú Thọ Province and Thái Nguyên Province with an area of 24,314.7 km², half of the size of Greater Ho Chi Minh City, the same for population size planning.

As Hà Tây was merged into Hanoi by a resolution of the National Assembly of Vietnam in June 2008, this metropolitan area will include Hanoi and six surrounding provinces.

As 2012, this Metropolitan area will include Hanoi and nine Provinces.^[2]

As of 2012, this metropolitan area has a population of 17 million, of which 4.6 million live in urban areas. By 2020, the numbers will be 20-22 and 12-13 million, respectively.

In 2025, Vietnam changed its administrative structure again, with new arrangements for provinces and local administrative areas. These changes affected how the Hanoi metropolitan area and surrounding region are defined, making older population figures difficult to compare directly with newer ones^[3].
