Population

LOOK

Do you live in a place with many inhabitants?

Do you know people who come from a different place?

READ 1. Population

The population of an area is the number of people who live there. It can be classified into two types.

Urban populations are people who live in cities.

Rural populations are people who live in villages and towns.

A census measures the size of a population.

2. Natural increase

Natural increase is the difference between the number of people who are born and the number of people who die in the same year.

The number of inhabitants in a place changes continually.

There is a positive natural increase when more people are born than die.

The population grows.

There is a negative natural increase when more people die than are born.

The population decreases.

3. Population distribution People like to live in places where there are job opportunities, a healthy climate and good services. Many people live on the coasts and plains in temperate zones.

Population density is measured by dividing the total number of inhabitants by the surface area of the place where they live.

Some countries and regions are more densely populated than others. In Australia there are huge, dry areas with no inhabitants, and there are only 2 inhabitants per square kilometre.

4. Population groups

Population can be classified by gender into male and female inhabitants, and by age into three main groups:

Young people under the age of 18

Adults between the ages of 18 and 64

Senior citizens over the age of 65 57

Do a census of your class. What is the population?

Classify your classmates by gender and age.

Many people leave their homes to live in another place.

This movement of population is called migration.

There are two main reasons:

Natural causes, for example floods, droughts and earthquakes, can cause migration.

Social factors, for example wars or political and religious problems, can also cause migration.

Also, people sometimes leave home to find work.

2. Internal migration

Internal migration is produced within the same country.

For example, there are often migrations from rural areas to cities. There are two main reasons:

The number of jobs in rural areas decreases.

Young people find better opportunities to study, work and live in cities.

3. International migration

Migration from one country to another is called international migration.

People who leave a country are called emigrants.

When they arrive in the other country, they are called immigrants.

People emigrate for many reasons. Some leave to find work, or to join relatives in another country. Others leave to escape from war and persecution in their own country.

In the past, many emigrants left Europe and went to other countries, such as the United States, to find better jobs.

Today, many immigrants come to the European Union from Africa, Latin America and other European countries to find better jobs.

Today, many young European adults also emigrate to study or work in a different country.

40 POPULATION

1. Population characteristics

Today the population of Spain is approximately 43 million inhabitants.

In 1900 it was 18 million inhabitants.

(See the chart.)

The number of immigrants is increasing.

There are now about three million immigrants.

Some come to work in Spain.

Others, such as senior citizens, come to retire here.

Population density is low compared to population density in other European countries, such as Germany, Belgium or France. It is 86 inhabitants per km2.

The population is not evenly distributed.

The coast and the Autonomous Community of Madrid are densely populated.

In contrast, other inland areas are sparsely populated.

In many Autonomous Communities, a high proportion of the population is found in the provincial capital.

Like other European populations, the Spanish population is getting older.

This means that the adult and senior population is growing more quickly than the population of young people.
