“…In formulating models for the number of births or the number of conceptions to a couple during a specified time, Perrin and Sheps (1964), Sheps and Perrin (1966), Singh (1963Singh ( , 1968), Singh and Bhattacharya (1970) and Pathak (1970) have assumed a constant duration for the "rest period" comprising the duration of pregnancy and post-partum amenorrhea. Srinivasan (1966), in his model for inter-live birth intervals, assumes the distribution of post-partum amenorrhea to be an asymmetrical triangle, while Yadava (1966) takes it to be a chi-square distribution.…”

“…Singh (1963Singh ( , 1966 has also extended the models (Singh, 1963(Singh, , 1966 to describe distribution of complete conceptions for a heterogeneous group of couples and has assumed that fecundability (p) follows beta-distribution in discrete time model. Pathak (1966) introduced one more refinement in Singh's discrete time model. He assumed that a certain proportion of fecund women are not susceptible at the beginning of the period because either they are pregnant or are in the postpartum amenorrhoea.…”

The study of pattern of female child birth is one of the most crucial area of human demography because it plays very important role in the building of a nation. In the present study, an attempt has been made to work-out the pattern of female child births among females belongs to different subdomains of population through the probability model and the parameters involved in the probability model under consideration has also been estimated. The suggested model, for illustration has been applied to an observed set of data taken from NFHS-III (2005-06) for the seven NorthEast states of India known as Seven Sisters.

“…The high levels of fertility, especially in the central region of India, are the major concern to the planners and policy makers. Therefore, analysis of birth spacing is of interest in this context since it can provide further insight into the mechanism underlying fertility change (Potter, 1963;Sheps, 1964;Pathak, 1966;Sehgal, 1971;Srinivasan, 1980;Njogu & Martin, 1991). Studies also revealed that birth spacing is preferred over other conventional measures of fertility because of its sensitiveness to small and short term changes in the reproduction rate (Singh, 1964;Sheps & Menken, 1972;Namboodiri, 1974;Namboodiri, 1983).…”

Birth spacing is one of the important aspects of reproductive health. Therefore, it is felt by demographers that birth spacing needs to be studied from time to time in view of the epidemiological transition taking place worldwide. Using the third round of National Family Health Survey-3 data, the central hypothesis of this paper is to find out the relative advantages of breastfeeding over other methods of contraception among non-sterilized women by using simulative approach of the Cox regression analysis in India and its regions. The results show that if women were not having amenorrhea period and had a high level of breastfeeding, the chance of not having next live birth was only two percent lower than those women who were using spacing methods in India. This pattern was found to be almost similar in all the regions of India except central and southern regions. There is no significant gain in postponing the next live birth has been observed in using the contraceptives than breastfeeding. An effort has also been made to apprise the policymakers of the interrelation between breastfeeding, postpartum amenorrhea, contraceptive use and birth spacing. Nonetheless, policymakers should promote programs that encourage both breastfeeding and contraceptive use. Breastfeeding has direct benefits for infant health in addition to its role in lengthening birth intervals beyond postpartum amenorrhea.
