Demographic transitions from one state to another -- such as from married to divorced or from working to not-working -- are often considered to depend not only on age but also on the duration in the status. Yet the traditional life table methodology to describe these phenomena can only account for one demographic time dimension (mostly age).
This paper is in line with recent IIASA efforts to generalize the life table approach to account for at least two relevant demographic time dimensions (age and duration). It presents a computer program that conveniently estimates the duration-dependent multistate life table model which was suggested in earlier papers by Douglas Wolf
