Like ecologists, urban ecologists think that cities form as a result of natural growth. This natural growth refers to urban expansion, immigration, and succession (new people moving in and replacing those that move out), and this is very much related to geography and the natural environment of a city.
There are many reasons for increased urban growth in the developing world. Some of which are: employment opportunities are greater within urban areas. better paid jobs in the cities, an expected higher standard of living , and more reliable food are all pull factors - reasons why people are attracted to the city.
Counties, townships, cities, and states collect some of their money from licenses and fees and state-operated businesses, but about half of state revenue comes from taxes. Two other sources of income are grants from the federal government and, in some states, lotteries. Some cities also collect sales tax.
Major issues and problems confronting US cities today include those involving fiscal difficulties, crowding, housing, traffic, pollution, public education, and crime. Several of these problems stem directly from the fact that cities involve large numbers of people living in a relatively small amount of space.
Threats. Intensive urban growth can lead to greater poverty, with local governments unable to provide services for all people. Concentrated energy use leads to greater air pollution with significant impact on human health. Automobile exhaust produces elevated lead levels in urban air.
The two causes of urbanisation are natural population increase and rural to urban migration. Urbanisation affects all sizes of settlements from small villages to towns to cities, leading up to the growth of mega-cities which have more than ten million people.
How did this mechanization of agriculture affect cities? Since fewer agricultural workers were needed, they moved to cities for jobs. Rapid industrialization had created many job opportunities.

A megacity is a very large city, typically with a population of more than 10 million people. Others list cities satisfying criteria of either 5 or 8 million and also have a population density of 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.
Cities, everywhere, are not sustainable. In fact, the average city-dweller consumes many more resources, and emits far more greenhouse gas, than their rural compatriots, anywhere in the world. Cities are hubs of consumption, connected by increasingly long and complex supply chains to resource centers around the world.

Well-connected cities grow faster, because they can more efficiently move goods and human capital to where it's needed most. The ten most populated states lose around $62 billion each year in potential economic activity due to traffic congestion. A diverse set of industries is crucial to success.
The shrinking of urban populations indicates a changing of economic and planning conditions of a city. Cities begin to 'shrink' from economic decline, usually resulting from war, debt, or lack of production and work force.
Answer Expert VerifiedIn many cases, the rise of cities forced many government to become more centralized and organized, since the population density was higher which required more public works, such as sewage lines, etc.
Explain. Impact of big cities can be both positive and negative. A positive impact would be the modernization of a given city in terms of transportation, agriculture and systems. A negative impact would be the destruction of a natural habitat or other natural forests for the sake of urbanization.

Causes of urban growthThe population of cities usually changes in one of two ways: Natural increase (or decrease) - this is the difference between the number of births and the number of deaths. Migration - this is the movement of people into or out of the city.
This could be a

Births and deaths are natural causes of population change. The difference between the birth rate and the death rate of a country or place is called the natural increase. The natural increase is calculated by subtracting the death rate from the birth rate.
