The number of people who live in urbanised areas in 2019 is 33,122,548 people (with the urbanisation rate at 34.4%). Since 1986, Vietnam's urbanisation rates have surged rapidly after the Vietnamese government implemented the Đổi Mới economic program, changing the system into a socialist one and liberalising property rights. As a result, Hanoi and Ho Chi Minh City (the two major cities in the Red River Delta and Southeast regions respectively) increased their share of the total urban population from 8.5% and 24.9% to 15.9% and 31% respectively. The Vietnamese government, through its construction ministry, forecasts the country will have a 45% urbanisation rate by 2020 although it was confirmed to only be 34.4% according to the 2019 census. Urbanisation is said to have a positive correlation with economic growth. Any country with higher urbanisation rates has a higher GDP growth rate. Furthermore, the urbanisation movement in Vietnam is mainly between the rural areas and the country's Southeast region. Ho Chi Minh City has received a large number of migrants due mainly to better weather and economic opportunities.
