We explain what a city is and some of its characteristics. Also, the main cities in the world and information about them.
What is a city?
A city is he name given to urban settlements of the human population of a nation, that is, the densely populated urban spaces artificially modified to house human communities, endowed in turn with political, economic and administrative functions and powers.
Every city is distinguished from rural centers in, fundamentally, the presence of industrial, economic and bureaucratic activities other than agriculture, of urbanizations in which vertical buildings (buildings or skyscrapers) predominate, and above all of the administrative centers of political power. (like the capitals).
There is no single criterion to define what is and what is not a city, at least based on the number of inhabitants. a city can have hundreds of inhabitants, or millions of themlike the large American megalopolises with more than 20 million resident citizens.
In many cases, in addition, cities encompass a more or less similar urban ring (the metropolitan area) of “dormitory” populations more or less integrated logistically, administratively and urbanistically into the “heart” of the city. city.
In fact, large cities have had to organize themselves based on smaller geographic and political units, in order to be governed. Reason why They are divided into municipalities or townshipsequipped with mayors and local or neighborhood representatives.
This classification also had its impact on the constitution of republican democracy, since the inhabitants had to be registered and organized to be able to exercise their vote in an orderly manner.
Another characteristic of cities is their permanence over time, that is, they they don't change location. Instead, they tend to expand, covering more and more territory as their population grows, a phenomenon known as expansion of the urban sprawl.
The phenomenon of expansion of the urban march It began centuries ago, when the end of the Middle Ages (approximately 15th century) brought with it the emergence of urban life as the dominant model, above life in agriculture, causing a considerable exodus from the countryside to the different Western cities. This coincided with the emergence of the bourgeoisie as the new ruling class, in place of the feudal lords (landowners).
Currently, the largest percentage (54%) of the world's population is located in the different existing cities. Paradoxically, such an urban population requires increasingly larger food production, coming from the agricultural world, since in the cities the primary sector of the industry is not usually foundbut the secondary, the transportation sector and the services sector.
