Death rate and how it affects population. Definition: Death rate (or mortality rate) of a country refers to the rate at which people (both adult and children) die in a country.
Generally, high death rate leads to population decrease or low population, while low death rate leads to increase in population.
Factors affecting death rate
(1) Ratio of male to female: When there are more males than females, there will be a low
child-bearing rate, which will reduce the population.
(2) Poor medical services: When medical services are poor, death rate tends to increase
(3) High rate of infant mortality: High rate of infant mortality leads to decrease in population.
(4) Poverty: High level of poverty among the people leads to high death rate, as such people may not have the means of taking care of their families.
(5) Natural disasters: Natural disasters like earthquakes, flooding can lead to high death rate
(6) Man-made disasters: The occurrence of man-made disasters like wars, conflicts and pollution is capable of leading to high death rate.
