摘要：This article deals with a new version of the inverse projection, the aggregate method for reconstructing historical population conceived, at the beginning of the '70s, by R.D. Lee. This new version, called differentiated inverse projection, can detect the differentiated incidence of mortality in the various age groups. This is possible because a further information is used: decreases according to age. After a methodological presentation of the new version, a demonstrative application is reported, which proves the improvement of the estimates produced by the differentiated version in comparison to those of the version by R.D. Lee.
