Changes in population

Population is the number of people who live in a specific area. To find out Spain's population, we can consult the municipal register and the national census.

Migration:

It's the movement of people from one country to another.

Net migration

is when someone arrives in a new country of residence.

Immigration

Emigration

is the difference between the number of immigrants and the number of emigrants.

Net migration

total immigrants - total emigrants

When the number of immigrants is higher, there is a positive net migration and the population increases. When the number of emigrants is higher, there is a negative net migration and the population decreases.
