This paper examines the relationship between female education and fertility in Kerala, a state in southern India known for its high literacy rates and significant socio-economic development. It explores the historical context of Kerala's emphasis on education, tracing the contributions of Christian missionaries, princely states, and social reform movements. With a focus on government policies and programmes that have promoted female education, the study delves into how educational attainment among women has influenced fertility rates, particularly through mechanisms like delayed marriage, improved contraceptive use, increased employment opportunities, and empowerment in decision-making. Kerala's Total Fertility Rate (TFR) of 1.8, below the national average, serves as a case study in demonstrating how education can drive demographic shifts. The socio-economic implications of reduced fertility—ranging from enhanced economic growth and improved maternal and child health outcomes to greater gender equality—are also discussed. Despite these achievements, challenges persist, including socio-economic inequalities and rural-urban divides. The paper concludes by offering policy recommendations to sustain progress in female education and fertility reduction.
