[A note on the use of information concerning the residence of surviving siblings to estimate emigration].
"Two improvements are presented in the previously developed method for measuring international emigration based on information provided by surviving siblings. The first is a simplification of the procedure for estimating surviving siblings when the information does not exist because they all live abroad. The second...is a procedure for estimating the distribution by age of the surviving emigrant siblings using models." The improved procedures are applied to data for Barbados. (summary in ENG)
