UNIT 9

POPULATION

Population is the people who live in a town, country or the whole world

We divide the population into 3 groups:

The child population - less than 16 years old
The adult population - between 17 and 64 years old
The elderly population - 65 years old and over

The population changes due to the birth rate, the death rate, the emigration and the immigration

The birth rate and the immigration INCREASE the population (there are more people)

The death rate and the emigration DECREASE the population (there are less people)

Emigration (emigrants) - Immigration (immigrants)

Emigrants: decrease population (If people leave, there are less people)

Immigrants: increase population (If people arrive, there are more people)


Remember! If you go on holidays to another city, town or country you are NOT an emigrant or an immigrant you are just a tourist!!


POPULATION AND EMPLOYMENT

Economically active population: THEY ARE ABLE (CAPABLE) TO WORK


The working population

The unemployed population

Economically inactive population

People who do unpaid jobs (they are not paid, like volunteers)

People who don't work for some reason: they are retired, they are students...



Economic activities

Three sectors:

Primary

It includes the activities that produce or obtain natural products

Secondary

It includes all the activities related to the transformation of natural products into manufactured products such as craft and industry

Tertiary

Activities that provide a service. Jobs related to health, education, transport, catering, etc.
