Mortality Rates

Definition

Mortality rates refer to the number of deaths within a population over a specific period of time, usually expressed as the number of deaths per thousand individuals.

Analogy

Imagine you have a jar filled with marbles representing people. If you count how many marbles are taken out (representing deaths) in a given time period compared to the total number of marbles initially present, you can calculate mortality rates.
