What factors affect human population growth?
Population depends on the rate of growth , as well as external factors.
Population is influenced by factors like birth rate & death rate .
Birth rate (Natality)- This refers to the number of newborns in a region at a given time.
Death rate (Mortality) - This refers to the number of deaths in a region at a given time.
Depending on whether birth rate/ death rate is more, the following trends are observed in a population:
Steady population - This is when the birth rate is equal to the death rate. There is neither increase/decrease in the population.
Declining population - This is when death rate is more than the birth rate.
Growing population - This is when birth rate is more than the death rate.
Another factor which influences population growth is competition .
