Here we introduce a stochastic equation for modelling population growth in cities, constructed from an empirical analysis of recent datasets (for Canada, France, the UK and the USA). This model reveals how rare, but large, interurban migratory shocks dominate city growth. This equation predicts a...

to the movement of the planets or the growth of cities. And if we're being honest, none of those things are exactly neatly ordered and easily predictable, either. Because I believe that mathematics is so powerful that it has the potential...
The Impact of Urbanization in China Urbanization is defined by the United Nations as movement of people from rural to urban areas with population growth equation to urban migration. 城镇化被联合国定义为人从农村运动到城市地区并成为城市人口的过程。一九七九年那是一个春天有一位老人在中国的南海边画了...
Also, other economic and demographic factors such as population density, urbanization, and shares of agriculture and manufacturing in GDP are related to investment in some types of infrastructure [[35], [36]]. Infrastructure services are demanded by consumers and firms, which the growth of GDP ...
●Secondly, think carefully whether you really understand the meaning of a term or the use of an equation(方程式). A good way to test your understanding is to explain a concept to a classmate or someone else. ●Thirdly, pay attention to things which have something to do with chemistry in...
unnecessary energy consumption, and even serious economic loss due to the extraordinary growth in personal mobility, and as a consequence of car ownership and car usage have continued rapid growth into the current century including in several cities in Indonesia (Saleh et al., 2017, Aggraini et ...
Additionally, using metrics of Scale-adjusted metropolitan indicator (SAMI) and the ratio of open space consumption to population growth rates (OCRPGR), we observe a trend towards more coordinated development between UOS and population, with a declining proportion of uncoordinated cities. Our long-...
The global effect captures the city-wide interactions between population via the gravity equation, and the spatial distribution of the active population is regarded as a two-dimensional gravity field. Analytical and numerical results suggest, despite the large number of complexities that influence urban...
