The second measure, rate of urbanization, describes the projected average rate of change of the size of the urban population over the given period of time. As of 2022, countries with more than 80% of people living in urban areas include the United States , Canada , Mexico , Brazil , Argentina , Chile , Japan , Australia , the United Kingdom ...
Urbanization over the past 500 years [13] A global map illustrating the first onset and spread of urban centres around the world, based on. [14]From the development of the earliest cities in Indus valley civilization, Mesopotamia and Egypt until the 18th century, an equilibrium existed between the vast majority of the population who were engaged in subsistence agriculture in a rural context ...
Based on this, the UN projected that the world population, 8 billion as of 2023, would peak around the year 2086 at about 10.4 billion, and then start a slow decline, assuming a continuing decrease in the global average fertility rate from 2.5 births per woman during the 2015–2020 period to 1.8 by the year 2100 (the medium-variant projection).
Urban areas are created and further developed by the process of urbanization. They are measured for various purposes, including analyzing population density and urban sprawl. Urban areas are generally found in the United States, Canada, Brazil, Mexico, Argentina, Chile, Japan, Australia, and many other countries where the urbanization rate is high.
The United Nations estimates that approximately 68% of the world's population will be living in urban areas by 2050. [3] Urbanization has vast implications including the urban planning, geography, sociology, architecture, economics, and public health of a region. [6] The rate at which urbanization occurs is also important.
