Population
1.Population growth.
Demography is the study of human populations.
Populations are never static. They rise or fall depending on the people who birth, died or migrate.
-The birth rate is the numbers of births in a date.
-The death rate is the numbers of died in a date.
-The birth rate minus the death rate results in the rate of natural increase.
2.Population density.
The total population of a territory is the number of people who live in that territory.
The population density is the number of people living in one square kilometre. It is calculated using that formula: Population density equal total population divided by area in km2.
Spain,s population density.
Spain has an average population density of 92 inhabitants per km2.
-Population distribution:
Rural population:
Population density is lower.
The rural population is usually older.
Urban population:
Population density is higher.
The urban population is usually younger.
One hundred years ago, Spain,s rural population was higher tan rural urban population.
Nowadays, Spain,s population is mostly urban.
The rural inland areas are the least populated.
The Autonomous Community of Madrid is an inland area with a large population.
The most populated areas of Spain are on the coast and on its two archipelagos.
3.Changes in Spain,s population
-Immigration minus emigration per 1.000 people results in the net migration.
-A population grows because there are more births than deaths or more people are moving in than moving out.

3.More than five million immigrants came to Spain because there was work and a high standard of living.
The Middle Ages:
-Spain,s population growth was very slow.
-The birth rate was very high but the death rate was also high too.
-The coast was more populated tan inland.
Contemporary times:
-The number of people living in the world has more tan doubled in the last 50 years.Likewise, since the mid 20th century,Spain experience a population explosión.The birth rate was still highbut the death rate fell.This was also a time of a great rural exodus.
New social changes have affected Spain,s population since 1.975. Women started working outside of the home, so they have less children. Life expectancy has increased a lot.
