"In this paper a probability model is proposed to describe the distribution of births to couples in first T years of marriage, when T is large and/or when couples use various methods of family planning. This model is derived on the assumption that conditional instantaneous risk of a conception, the incidence of foetal loss and the chance of attaining following a child birth are functions of parity....The application of the model in evaluation of family planning programme changes in the child bearing pattern is illustrated."
