SinghBrijesh SinghK.K. 3201473Human fertility has a central importance in demographic analysis as the births are vital component of population growth. The study of fertility provides important information about womens reproductive behaviour and attitude. Factors which influence fertility are very crucial and provide the idea about the population change. Keeping in view, many studies have been carried out to study the factors which influence fertility. In this regards, Bongaarts (1978) have proposed a model considering four major factors such as marriage, contraception, induced abortion and lactational infecundability to explain overall variation in the total fertility. In the present study one more factor sterility is incorporated which plays an important role to explain total fertility. Estimation of induced abortions has its own complicacy. The major problem in estimation of abortion is the availability of reliable data for the developing country like India. Its study becomes even more complicated due to the variability of cultural and behavioral attitude of the females. Here a simple and modified model has been used to estimate the abortion index and which is further utilized to estimate the number of birth averted due to abortion for the different major states of India.]]>Agrawal, S.,20042004Arnold, F., S.
