Factors in Population Growth

The natural increase of a population depends on the number of births and deaths. If the number of
births is greater than the number of deaths at any given point in time there will be natural increase in
the number of people. Typically, the growth rate of a population is given in terms of the birth rate
(number of births per 1000 people per year) and death rate (number of deaths per 1000 people per
year).

1.Write an equation that expresses the growth rate of a population in terms of the birth rate and death rate.

2.What circumstances might result in a high birth rate for a population? A low birth rate?

3.What circumstances might result a high death rate for a population? A low death rate?

4.Look at these charts of Birth and Death Rates. If both birth rates and death rates are declining worldwide, why is the world’s population still increasing? Based on this birth rate and death rate information, what could you say about the world’s growth rate in recent years?
