ANALYSIS OF THE PARITY PROGRESSION RATIOS

Abstract

With changing reproductive patterns of the population overtime, it has become rather more important to know the process of family building as to how many women are moving from the lower parity to higher parity and in how much time the pattern of fertility advancement from ith parity to (i+1)th is dealt through Parity Progression Ratios. During the recent years, many authors have studied the probability models in fertility particularly in parity progression ratios involving stochastic processes and renewal theory. Such studies have played important roles in fertility analysis. In the present study, an attempt has been made to work-out the distribution of maternal age over the reproductive span of woman and the probability distribution for woman proceeding to next higher parity. Finally, a life table on the parity progression has been constructed.
