Detailed Solution

Natality means the birth rate, while mortality means the death rate in a population. In population studies, scientists use natality and mortality to measure growth and decline. These two terms describe how many individuals are being added or removed from a population over a certain period.

Natality (Birth Rate)

Refers to the number of births in a population per unit of time.

High natality means the population is increasing.

Mortality (Death Rate)

Refers to the number of deaths in a population per unit of time.
Measured as number of deaths per 1,000 individuals per year.
High mortality means the population is declining.
