The Population Growth Rate refers to the rate at which the number of individuals in a population increases over a specific period, usually expressed as a percentage. This rate is influenced by factors such as birth rates, death rates, immigration, and emigration. A positive growth rate indicates that a population is increasing, while a negative growth rate suggests a decline. Governments and organizations often monitor the population growth rate to understand demographic changes and plan for future needs. For example, a high growth rate may require more resources, such as housing and education, while a declining population might lead to labor shortages and economic challenges.
