• the number of births per 1,000 people, per year

• the number of deaths per 1,000 people, per year.

• the study of human populations

the study of human populations is...

• Population growth

• Natural increase

• Demography

• Birth rate

To know the "natural increase" we need:

• Birth rate - death rate

• immigrants - emigrants

• death rate - birth rate

Population density shows:

• How many births and deaths an area has.

• the amount of immigrants and area has.

• how populated an area is. It is always uneven

We calculate population density by

• Dividing the number of emigrants and immigrants of a place by the size of the area.

• dividing the number of inhabitants by the size of the area they live in. Total population / total land area Km2

• dividing the number of people in an area by the number of births.

when the birth rate is higher than the death rate and the absolute population increases, there is a...

• positive natural increase

• negative natural increase

• actual increase of population

What's the population density of a region if 3.000.000 people live there and the region has a surface area of 600.000 km2?

• 5 inhabitants / km2

• 50 inhabitants / km2

• 20 inhabitants / km2

In the year 2010 in Malaga. The birth rate was 2000 babies and the death rate was 2200. Was the natural growth positive or negative?
