2. WORLD POPULATION The world POPULATION si nearly seven
billion people and is growing everyday. The most populated
countries in the world are China and U.S.A The least populated
countries are Canada and Australia. Overpopulation results in a
massive depletion of the Earth's natural Resources.
3. POPULATION Population is the Numbers of people who live in a
particular area. Population can grow thanks to natural growth and
migratory growth. Natural growth is the difference between the
Number of people who are born in an area in one year and the Number
of people who die. Migratory growth is the difference between the
Number of inmigrants who come and the Number of emigrants who leave
the place.
4. Work People work in three economic sectors: The primary
sector includes jobs which obtain Resources from nature ( fishing,
mining, livestock farming and agriculture). The secondary sector
includes jobs which transform natural Resources into manufactured
products. The terciary sector includes jobs which provide
services.
5. Population in Spain The population in Spain is not
distributed equally. Some areas are densely populated, such as big
cities like Madrid and Barcelona. Other areas are sparcely
populated such as rural areas.
6. Today, the population is over 47 millions thanks to positive
natural growth and inmigration. Positive natural growth happened
when the birth rate is high and the death rate is low. Negative
natural growth happened when the birth rate is low and the death
rate is high. Nowadays, several changes slowed down the death rate
and the population increase in Spain: economy developed, nutrition
improved and medical advances.
7. Migration An Emigrant is a person who leaves their country
to live in another country. An Inmigrant is a person who comes to
live in a foreign country. There are three types of migration:
International emigration is migration from one country to another
Internal migration is migration within the same country ( usually
the people moved to the big cities looking for work). International
inmigration, people from countries in South America, Eastern Europe
and Africa come to Spain looking for work.
8. Population Density Population Density show us is a place has
a large or small population in relation to its area. It's the
Number of inhabitants per square kilometres. Area is a measure in
square kilometres ( km2). Population Density: Number of
inhabitants: surface area. Inland provinces are less populated than
reas on the coast and on the Islands except Madrid. Within Each
province the population is concentrated in the cities but the
countryside is sparcely populated.
9. Population and jobs Population can be divided into to groups
related to work: Active population: people who are of legal working
age (16 to 67 ) healthy and able to work. Employed: They are
working and earn money in exchange. Unemployed: They are looking
for work. Inactive population: people who are not of legal working
age (children and retired people) and people who do not receive a
