The total fertility rate (TFR) is a crucial demographic indicator used to assess population growth and reproductive health within an economy. It represents the average number of live births a woman would have during her reproductive years, typically defined as ages 15 to 49, assuming she experiences the exact current age-specific fertility rates throughout her lifetime. Understanding the TFR helps policymakers evaluate population trends, inform family planning initiatives, and address socioeconomic implications of changing fertility patterns, which are significant in the context of sustainable development and resource management.
