Complete birth histories of 90,303 ever-married women aged 15-49 years from the 1998-99 National Family Health Survey were used to compute birth-order-specific induced-abortion ratios. The influence of maternal and social variables was assessed using logistic regression. The overall induced abortion ratio was 17.04 per 1000 pregnancies. The lowest ratio was 5.27 per 1000 pregnancies for first birth order, increased to 25.81 for third birth order and then declined marginally and non-linearly. Education of women was the most important factor. Having the first and second child late was related to previous induced abortion. Living in rural areas reduced the odds of induced abortion. Nationally, sex of the previous child was not significantly associated with induced abortion.
