We explain what a city is and some of its characteristics. Also, the main cities of the world and information about them.
What is a city?
A city is the name given to the urban settlements of the population human of a nation, that is, urban spaces that are densely populated and artificially modified to house communities human beings, endowed in turn with political, economic and administrative functions and attributions.
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 capitals).
There is no single criterion to define what a city is and what is not, at least based on the number of inhabitants. A city can have hundreds of inhabitants, or millions of them, like the great American megalopolises with more than 20 million citizens residents.
In many cases, in addition, cities comprise a more or less similar urban ring (the metropolitan area) of "bedroom" populations more or less logistically, administratively and urbanistically integrated into the "heart" of the city. city.
In fact, large cities have had to organize themselves on the basis of smaller geographic and political units in order to be governed. Reason for which they are divided into municipalities or municipalities, equipped with mayors and local or neighborhood representatives.
This classification also had its impact on the constitution of the democracy Republican, since the inhabitants had to be registered and organized to be able to exercise the vote in an orderly manner.
Another characteristic of cities is their permanence in the weather, that is, they do not change location. Instead, they tend to expand, encompassing more and more territory as their population grows, a phenomenon known as theexpansion of the urban area.
The phenomenon of expansion of urban walking 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 rise of the bourgeoisie as the new ruling class, instead of the feudal lords (landlords).
Currently, the largest percentage (54%) of the world's population is located in the different existing cities. Paradoxically, similar urban population requires a food production, coming from the agricultural world, increasingly larger, since cities do not usually find the primary sector of the industry, but the secondary, the transport sector and the sector services.
