Population refers to a group of organisms of the same species inhabiting a particular geographic region. In human contexts, the population often pertains to the number of people residing in a particular area, whether a city, country or the world as a whole. However, the definition of population extends beyond mere numbers. It includes the demographic characteristics of individuals, such as age, gender, education, employment, health, and ethnicity. Each attribute has significant implications for understanding population dynamics and how populations grow, shrink, and change over time.
