What does Population Growth refer to?

• A. The decrease in the number of individuals in a population
• B. The increase in the number of individuals in a population
• C. The spread of diseases within a population
• D. The geographic expansion of a population

Answer: (B)

Population Growth means the increase in the number of individuals in a population. It happens when the number of births plus those who move into the population (immigration) exceeds the number of deaths plus those who leave (emigration). In other words, it’s about a rising population size over time, not about how spread out people are or how many people get sick. So the best choice is the one that describes an increase in the number of individuals. It’s not about a decline in population, which would be a decrease; it’s not about how diseases spread within the group, which is about disease dynamics; and it’s not about expanding the area where people live, which is geographic expansion rather than changing population size.
