title: Estimating the time elapsed since first marriage with cross-section data.
abstract: "This article shows how Hajnal's method of estimating the mean age at first marriage with period data may be extended to estimate also the mean time elapsed since first marriage.  The latter may thus be estimated in fertility analyses that exploit cross-sectional data even when the date of marriage is not known.  However, simulations indicate that, under certain circumstances, such an estimate may be seriously biased.  An application to data drawn from the 1981 Italian census is presented." (SUMMARY IN FRE)
