#### Slide 16 -Slide

Natural increase
The birth rate is the number of babies born in a year per 1,000 inhabitants. The death rate is the number of deaths in a year per 1,000 inhabitants.

#### Slide 17 -Slide

Natural increase
The birth rate is the number of babies born in a year per 1,000 inhabitants. The death rate is the number of deaths in a year per 1,000 inhabitants.

Birth rate - death rate = natural increase.

#### Slide 18 -Slide

Natural increase
The birth rate is the number of babies born in a year per 1,000 inhabitants. The death rate is the number of deaths in a year per 1,000 inhabitants.

Birth rate - death rate = natural increase.
Example for the Netherlands:
Birth rate  = 10 o/oo.
Death rate = 8 o/oo.
Natural increase = 10 - 8 = 2 o/oo.

#### Slide 19 -Slide
