Chengdu [a] is the capital city of the Chinese province of Sichuan. With a population of 20,937,757 at the 2020 census, [5] it is the fourth most populous city in China, and it is the only city with a population of over 20 million apart from direct-administered municipalities. It is traditionally the hub of Western China. Chengdu is in central ...
Among them, the total permanent population of Chongqing, Shanghai, Beijing and Chengdu is above 20 million. [7] Shanghai is China's most populous urban area, [ 8 ] [ 9 ] while Chongqing is its largest city proper , the only city in China with the largest permanent population of over 30 million.
Demographic economics or population economics is the application of economic analysis to demography, the study of human populations, including size, growth, density, distribution, and vital statistics.

According to Malthusian theory, population growth takes place in a geometrical fashion. When population growth takes place, food supply decreases and this is always an indicator of more people depending on the same amount of resources. It basically means that food supply will be diminishing due to strains put on the available resources.
Evolutionary game theory was first developed by Ronald Fisher in his 1930 article The Genetic Theory of Natural Selection. [26] In 1973 John Maynard Smith formalised a central concept, the evolutionarily stable strategy. [27] Population dynamics have been used in several control theory applications. Evolutionary game theory can be used in ...
[7] [8] [9] (d) the theory as a whole was explored quantitatively. [10] [11] Traits that were complementary to the technological environment generated higher level of income, and therefore higher reproductive success. Testable predictions of this evolutionary theory and its underlying mechanisms have been confirmed empirically [12] and ...
P 0 = P(0) is the initial population size, r = the population growth rate, which Ronald Fisher called the Malthusian parameter of population growth in The Genetical Theory of Natural Selection, [2] and Alfred J. Lotka called the intrinsic rate of increase, [3] [4] t = time. The model can also be written in the form of a differential equation:
