An age-sex distribution diagram, also known as a population pyramid, is a graphical representation that shows the distribution of a population by age and sex. It consists of two back-to-back bar graphs, one for males and one for females, with the youngest age groups at the bottom and the oldest at the top.
Dependency Ratio: This term refers to the ratio between the economically dependent (typically young and elderly) population and those who are working-age. A high dependency ratio indicates an increased burden on the working-age population.
Birth Rate: The birth rate is the number of live births per 1,000 people in a given year. It helps determine whether a population is growing or declining.
Life Expectancy: Life expectancy refers to how long on average individuals in a certain population can expect to live. It provides insights into healthcare systems, quality of life, and overall well-being within populations.
