The Kinh group does represent much of the cultural and political landscape of Vietnam. Vietnam's population may be expected to approach to 100 million by the end of 2023, making it the 15th largest country by population in the world. [7] [8] It is predicted that by 2035, Vietnam will become an aged society. [9] [10]
The development of population ecology owes much to the mathematical models known as population dynamics, which were originally formulae derived from demography at the end of the 18th and beginning of 19th century. [8] The beginning of population dynamics is widely regarded as the work of Malthus, [9] formulated as the Malthusian growth model.
The 2019 Vietnamese census, officially the 2019 Viet Nam Population and Housing Census (Vietnamese: Tổng điều tra dân số và nhà ở năm 2019, lit. 'Total investigation on the population and housing of the year 2019') was the fifth national census of Vietnam since the country's reunification, [1] and the eighth census conducted by the General Statistics Office of Vietnam.

Population models are used to determine maximum harvest for agriculturists, to understand the dynamics of biological invasions, and for environmental conservation. Population models are also used to understand the spread of parasites, viruses, and disease. [2] Another way populations models are useful are when species become endangered.
The first principle of population dynamics is widely regarded as the exponential law of Malthus, as modelled by the Malthusian growth model.The early period was dominated by demographic studies such as the work of Benjamin Gompertz and Pierre François Verhulst in the early 19th century, who refined and adjusted the Malthusian demographic model.
