Answer:
B. natality + immigration = mortality + emigration
Explanation:
Migration refers to the movement of a group of people from one geographical region (location) to another geographical destination in search of better living conditions, work or social amenities.
Migration selectivity can be defined as the likelihood or tendency that a subset (part) of a group of people are going to move (migrate) out of a particular geographical location or area.
Some of the factors that influence migration selectivity are income level, age, education, gender etc.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Therefore, the equation which would create a stable population is given by the formula;
Natality + immigration = mortality + emigration.
