The study demonstrates that, regardless of location, a pronounced reduction in fertility is achieved in Sri Lanka by the completion of junior secondary or higher levels of education; the reduction seems to be more marked in rural than in urban areas. Increased efforts to ensure that a significantly higher proportion of girls in Sri Lanka complete at least the junior secondary level would be likely to effect a significant reduction in fertility. It is therefore important in developing countries to explore the potential influence of female educational attainment as an effective weapon towards fertility reduction and to ascertain the extent of the decline in fertility produced by varing degrees of education, according to various characteristics.
