Metropolization is the process of urban growth of a city and its constitution as the centrality of a Metropolitan region, that is, an area composed of several municipalities that combine the same spatial-territorial dynamics. The metropolis is seen as the zone in which other cities become economically dependent and interconnected. Among the examples of metropolises in Brazil, we have the cities of São Paulo, Rio de Janeiro, Belo Horizonte, Salvador, Goiânia, Porto Alegre and many others.
To understand the logic of metropolization (and, later, demetropolization), it is necessary to consider the following basic premise: industrialization tends to induce urbanization, that is, when a city or a region becomes industrialized, the tendency is that, over time, its population rises, as well as the number of households and the horizontal growth of its geographic space urban.
It was thus throughout history that he narrated the successive processes of industrialization around the world and their consequent urbanizations and metropolizations. In the 18th century, at the height of the Industrial Revolution, the great cities of Europe already had the largest populations in the world. However, the pace of population growth intensified more and more.
In the year 1850, London – then the main world center – reached three million inhabitants; 50 years later, this population already totaled seven million, thanks to the effects generated by the first two Industrial Revolutions. New York, thanks to the great migratory wave coming from Europe and the industrialization and financialization of its economy, was the first city to surpass 10 million inhabitants, in the 1930s.
Therefore, what we can notice is that the great capitals of the developed world were the first to industrialize and, therefore, the first cities to go through the metropolization process. Thus, until the mid-twentieth century, cities with large populations were synonymous with modernity, which changed in later decades.
From the second half of the 20th century, underdeveloped countries began to industrialize, thanks to the migration and expansion of industries and multinational companies that have settled in peripheral countries in search of easy access to raw materials, cheap labor and a large market consumer. Thus, countries like Brazil learned about their metropolization processes, such as those that took place in São Paulo and Rio de Janeiro, which, at the end of the century, were transformed into megacities (cities with more than 10 million population).
The problems of metropolization
It is known that any urban formation that takes place in a fast and disorderly way causes various social upheavals and economic-structural problems. In the 18th and 19th centuries, the great cities of Europe experienced chaos thanks to the high rates of urban concentration and the appalling working conditions to which workers (the majority of the population) were submitted. Uncontrolled urbanization and the lack of structure for the population affect the formation of the process of urban macrocephaly.
As a result, developed countries adopted policies for ordering and controlling their cities, sometimes carrying out urban reforms, sometimes revitalizing areas that were previously relegated to chance. Thus, cities like Paris, London and New York, despite being large megalopolises, abandoned the world leadership in number of inhabitants. Currently, this post belongs – with the exception of Tokyo – to cities located in underdeveloped countries. These cities now suffer the same social upheavals that developed cities once suffered, with the grievance of not having the same financial resources to free themselves from their conditions of misery.
Demetropolization and the growth of medium-sized cities
You've probably heard the following phrase at some point: “life in the big city is not easy”. Real estate is always more expensive (and also appreciates faster), traffic always presents problems, everything stays far from everything, not to mention environmental disturbances unique to cities, such as the Heat Islands and Inversion Thermal.

Due to this chaotic dynamic of large cities, their geographic space – except in a few cases, when good urban planning is carried out – it becomes unattractive for investment and for the installation of large companies. This factor, associated with the so-called “Fiscal War”, enables the formation of an old process in central countries and recent in emerging countries: a demetropolization.
This process occurs when there is a certain "escape" of companies that, due to the reasons explained above, migrate to the interior of the country or even to other regions of the globe, as long as this represents improvements in their services and an increase in their profits. In addition, in industrializing countries, the trend is to reduce the supply of raw materials and consolidation of labor rights, which does not interest the owners and shareholders of the companies that make up the great capital.
Thus, while the occurrence of demetropolization of large cities is observed (and the consequent fall in population growth), there is an increase in the so-called Medium Cities and smaller metropolises. Therefore, there are great concerns that, with the disorderly growth of these cities, the urban problems previously experienced in large metropolises will be repeated. To avoid this process, the State needs to regulate the economy a little more, establishing criteria and limits for urbanization and industrialization of cities, in addition to promoting measures to reduce social inequalities and the adequacy of infrastructure on the outskirts of the major cities.
