Estimated bounds of disability-free life expectancy (DFLE) and proportion of life spent disability-free for the 1907 and 1912 U.S. birth cohorts. The upper left (right) panel shows the estimated bounds of DFLE along with life expectancy for the 1907 (1912) birth cohort from age 81 (76) to 90 (90). The lower panels show the estimated bounds of the proportion of remaining life spent disability-free. The 95% confidence intervals are shown as dashed lines. For the 1907 (1912) birth cohort, DFLE and proportion of remaining life spent disability-free are calculated using the monotonicity assumption for ages from 81 (76) to 83 (78).
