Non-Reproductive Life Tables for India and States

An attempt is made here to demonstrate that very useful information about fertility in a population can be obtained from the age-specific fertility rates (ASFR) by Constructing Non-Reproductive Life Tables (NRLT). NRLT is constructed by assuming that a hypothetical cohort of women, not affected by mortality (and/or migration), experiences in its reproductive life time the given set of ASFR by Single years of age. From the NRLT several summary Indexes are obtained which provide more information on fertility in a population than only Total Fertility Rate (TFR), commonly used in fertility analysis. From the same ASFR, a Reproductive Life Table Parity Distribution is computed, from which Parity Progression Ratios (RLT-PPR) and Closed Birth Intervals (RLT-CBI) are obtained. All these measures being standardized measures are very useful in comparing fertility over time & between populations. Further, a methodology is presented for making ASFR projections using Revised Sivamurthy s PC Model for representing ASFR schedule. The Indian data are used to illustrate the application of these methods. It is hoped that all countries will publish these Tables as part of their Official Statistics.... Mehr
