Three factors have come to the forefront as the main evolutionary influencers in urban areas: the urban microclimate, pollution, and urban habitat fragmentation. [8] These influence the processes that drive evolution, such as natural and sexual selection, mutation, gene flow and genetic drift.
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 ...
Pull factors towards urban areas include expansion of economic opportunity and the infrastructure of cities as administrative centers [2] [7] Shandra recognizes the relationship between push and pull factors, arguing that rural conditions, specifically environmental scarcity, cause decreasing income, decreased stability, and increased health ...
Measures for urban sprawl in Europe: upper left the Dispersion of the built-up area (DIS), upper right the weighted urban proliferation (WUP).

Osborn, [17] firstly by Osborn in his 1941 letter to Mumford and later by Mumford, generally condemning the waste of agricultural land and landscape due to ...

Urban geography is the subdiscipline of geography that derives from a study of cities and urban processes. Urban geographers and urbanists [1] examine various aspects of urban life and the built environment. Scholars, activists, and the public have participated in, studied, and critiqued flows of economic and natural resources, human and non ...
The unequal distribution of city sizes and lack of convergence on one equilibrium size are relatively well understood. Henderson's model of urban system relies on three sets of factors that influence the size of cities: land inputs, labor, and capital. The model formally relates the benefits of economies of agglomeration and congestion cost.
Counterurbanization is the process by which people migrate from urban to rural communities, the opposite of urbanization. People have moved from urban to rural communities for various reasons, including job opportunities and simpler lifestyles. In recent years, due to technology, the urbanization process has been occurring in reverse.
