Population Pyramids: Population pyramids are graphical representations that show the age-sex distribution within a population. They provide insights into birth rates, death rates, life expectancy, and overall population growth.
Dependency Ratio: The dependency ratio measures the proportion of non-working (dependent) individuals (such as children and elderly) compared to working-age (productive) individuals in a population. It helps analyze economic implications related to healthcare costs, social security, and labor force.
Urbanization: Urbanization refers to the process of an increasing proportion of a country's population living in urban areas rather than rural areas. It is often associated with demographic shifts and changes in economic activities.
