The levels and trends of human fertility can be obtained from the descriptive study of the real data. But some inherent characteristics of this phenomenon namely fecundability, sterility, etc. can be estimated only by applying appropriate models to the real data. Here, an attempt has been made to explore the uses and importance of the probability models relating to human fertility through real data. In this study, different probability models have been considered to estimate the parameters by applying them to the data of the First Birth Interval in different major states of India obtained from National Family Health Survey - III.
