IN estimating the number of births averted, the contraceptive retention rates play a vital role. In doing so, the data requirement of retention rates will have to be for a longer period. Normally the data based on follow-up studies are of a short duration of one or two years, thus necessitating the use of the continuation curves for extrapolating the retention rates.
