In each cases special attention ought to be given to institutionalized populations often excluded from surveys. On the one hand, health expectancy computed with the Sullivan technique displays the current health composition of an actual population adjusted for present mortality levels. But, the results of the Sullivan methodology are restricted in that they point out nothing in regards to the anticipated life cycle events of individuals exposed to current morbidity conditions. Therefore, this measure provides a robust indication of the impact of present transition charges for particular person life cycles and population.
