Definition: Sullivan method
A very simple method to compute health expectancies. It combines data issued from a regular period of life table on the one hand and from cross-sectional survey providing prevalence of given health dimension on the other hand, for instance disability. The age-specific prevalence is directly applied to the person-year of the life table: it provides the total number of years spent with disability, the total number of years lived without disability, and summing both, the total number of years lived.
