Population Migrations


Population migrations date back to prehistoric times. Man seems to be constantly looking for new horizons. In the past, millions and millions of Europeans and Asians have migrated to all parts of the world, conquering and populating continents such as America, Oceania and Africa.

The reasons that justify migration are numerous (political-ideological, ethnic-racial, professional, economic, natural disasters, among others), although economic reasons are predominant.

The vast majority of people migrate in search of better living conditions. Every migratory act has repulsive causes (the individual is forced to migrate) and / or attractive (the individual is attracted to a particular place or country).


Migratory Movements Occur for Numerous Reasons

It is considered emigration as leaving one area to another;immigration It is the entrance of people into an area. Migrations can be internal, when they occur within the country, and external, when they occur from one country to another. Can still be permanent or temporary.

Migration Types

Nomadism

Demographic movement consisting of the constant exchange of housing area. Nomadism can be found in backward-living people who live by gathering (hunting, fishing and gathering) and by nomadic herding. Gypsies are a very characteristic example of this movement.

Transhumance

It is a rhythmic movement of constant coming and going. It is therefore a population movement from one region to another, usually determined by climatic reasons. It is very characteristic of the Eskimos, who in summer leave for regions of Tundra and, in winter, return to the Taiga. In northeastern Brazil, the demographic movement can be considered with transhumance: during the drought they flee from this area, returning with the rains.

Commuting or daily

These are daily movements from the periphery to the city and vice versa. Individuals work during the day in the city and return at the end of the day to their place of residence. These movements are characteristic of urbanization, as they force workers to live farther and farther from the city. They are the daily migrations.


Daily migratory movement

Campo - City

These are displacements of rural populations to the city. There is therefore a shift from rural to urban activities (industry, commerce and services). The departure from the countryside is partly justified by a phenomenon of demographic pressure, since if in the period before World War II mortality was high, its fall after the war promotes imbalance between the population, economic activities and its maintenance.


Migration from the countryside to the city - rural exodus

City - Countryside

When there is an exchange of people from urban to rural areas, the process called ruralization.


Ruralization - change from city to country

Countryside - Countryside

This migration uncle was very significant in Brazil between the 1970s and 1990s, especially when the population of Rio Grande do Sul migrated to the midwest and north of Brazil.


Porto dos Gaúchos is a Brazilian municipality in the state of Mato Grosso. The name came from the fact that the core trainers that originated the current city came from the state of Rio Grande do Sul.

City - City

It is a very significant movement in Brazil. There are a large number of people who migrate from small and medium cities to large ones. Many of these people have already completed the rural exodus. Currently, many Brazilians migrate from the metropolises to the smaller cities in search of quality of life.
