Natural+Population+Increase

Natural Population Increase involves the Birth Rate (number of births per 1000 people in a year) and the Death Rate (number of deaths per 1000 people in a year).

To find the Natural Population Increase (or Decrease!) you subtract the death rate from the birth rate. For instance: Birth Rate 45/1000 Death Rate 31/1000 Natural Population Increase of 14/1000

For every 1000 people the population will go UP 14 people in a year. If you had a population of 1,000,000 the population would go up by 14,000 in a year.
