Population - Mortality: As noted above, the science of demography has its intellectual roots in the realization that human mortality, while consisting of unpredictable individual events, has a statistical regularity when aggregated across a large group.
Just as fertility measures childbearing, the mortality rate is a measure of the number of people who die.
The crude death rate is a number derived from the number of deaths per 1, people per year. When analyzed together, fertility and mortality rates help researchers understand the overall growth occurring in a population.
Ethiopia has a population density of 83 people per square mile (/square mile), which ranks rd in the world. The mortality rate of mothers while giving birth is high.
with a growth rate of % per year. If Ethiopia follows its current rate of growth, its population will double in the next 30 years. Mortality rate is the rate of death in a population.
The two are often used together to calculate the prevalence of a disease — e.g., measles — and how likely that disease is to be deadly, particularly for certain demographics. World Population Ageing Population Division, DESA, United Nations 5 I.
