Question

How are tribes modified under the pressure of urbanization?

Answer 1

Urbanization refers to the population shift from rural to urban residency, the gradual increase in the proportion of people living in urban areas, and the ways in which each society adapts to this change.[1] It is predominantly the process by which towns and cities are formed and become larger as more people begin living and working in central areas.[2] Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth: urbanization is "the proportion of the total national population living in areas classed as urban", while urban growth refers to "the absolute number of people living in areas classed as urban".[3] The United Nationsprojected that half of the world's populationwould live in urban areas at the end of 2008.[4]It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized.[5] That is equivalent to approximately 3 billion urbanites by 2050, much of which will occur in Africa and Asia.[6]Notably, the United Nations has also recently projected that nearly all global population growth from 2017 to 2030 will be absorbed by cities, about 1.1 billion new urbanites over the next 13 years.[7]
