Question

Natality is

• A. number of births in a population during a given period
• B. number of individuals in a population per unit area
• C. number of deaths in a population during a given period
• D. the difference between the number of births and deaths per capita

Answer 1

The correct option is A number of births in a population during a given period

The number of births in a population during a given period is known as natality (N). It has a positive effect on population density as it results in addition of individuals from a population.
Mortality (D) is defined as the number of deaths in a population during a given period.
Population density is the number of individuals of a population per unit area.
The difference between the birth rate (number of births per capita) and death rate (number of deaths per capita) gives us the value for r, i.e, the intrinsic rate of natural increase in a population.
