In many countries, contraceptive use is one of the most important proximate determinants which affect fertility through socio-economic factors. Increasing mean age at marriage and declining marital fertility were two main causes that contributed to fertility transition in Sri Lanka. From the beginning of the 1970s’, modern contraceptive technologies have made a significant contribution to the fertility decline in Sri Lanka. During 1995-2000, Sri Lanka has reported a Total Fertility Rate (TFR) of 1.9, indicating that Sri Lanka has reached below replacement level fertility. However, the latest Sri Lanka Demographic and Health Survey (SLDHS) shows that there is an upturn in TFR in Sri Lanka reporting a TFR of 2.3. The effectiveness of a contraceptive method mainly depends on quality of practice. Modern contraceptive technologies are more effective than traditional methods in preventing pregnancy. Although evermarried and currently married educated women in Sri Lanka have a good knowledge of modern contraceptive methods, the data suggests they are less likely to use them when compared to less educated women. Instead, they use traditional contraceptive methods. Therefore, it is important to explore the factors influencing the rejection of modern contraceptive methods among educated women in Sri Lanka.
