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.

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.

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.

Population growth #1

Natural population growth

Number of births

Number of deaths

Natural increase: The difference between births and

deaths, given as a percentage.

Social population growth

Growth of the population because there is more immigration than emigration.
