The term "Adult Population" refers to individuals aged 18 years and older within a specific geographic area, such as a country or city. This demographic is significant for various studies, including those related to economics, health, and social behavior. Understanding the adult population helps governments and organizations plan services, allocate resources, and implement policies effectively. The adult population can be further analyzed by factors such as age, gender, education level, and employment status. These characteristics provide insights into societal trends and challenges. For example, the adult literacy rate and employment rates are crucial indicators of a country's development and overall well-being.
