What is meant by birth rate and death rate?
Birth Rate is the term used to define the number of babies born every year per 1000 people in a population. Death Rate is the term used to define the number of deaths every year per 1000 people in a population. Natural increase in a population occurs where Birth rate is greater than death rate.
