A world of migrants. Population movement

What is migration?

Migration is the movement of people to new location, either temporary or permantly. Includes:

-Emigration: leaving a place.

-Inmigration: arriving in a new region or country.

Net migration rate (saldo migratorio) plus natural growth (crecimiento natural) equals the real growth (crecimiento real) of the population.

-Economic (e. g. searching job).

-Political and religious (wars, persecutions...).

-Enviromental (natural disasters).

Social, cultural and psychological (e. g. to study or to change life).

-For the migrant: new opportunities, but comes with personal costs (family, adaptation...)

-For the country of origin: loss of people in age of work; lower unemployment; incomes from inmigrants.

-For the destination country: boosts the workforce, stimulating economic growth; rejuvenates population.

Migration flow refers to the number of migrants entering or leaving a country or region during a period of time.

Between 16th and XIXth centuries transoceanic migration was from Europe to America and the colonies (Australia, India, Argeria...)
In recent decades, because of economic inequality, crisis, conflicts, Internet and transports, migration has acquired unprecedent dimensions from less economically developed countries with high population growth (LEDCs) to more economically developed countries (MEDCs) with ageing population.
