Figure 3. Observed and projected variation in the maximum survivable age (MSA).

Figure 3.

( a) In humans, the probability of death q at age x ( q x; red line) increases at an approximately log-linear rate with age (black lines; 95% CI), shown here for the birth cohort of Jeanne Calment (d.122.5 years; circle). Projection of this log-linear increase to log( q) = 0 provides the MSA, the upper limit of human survival, shown here for ( b) observed and projected global populations 5 and ( c) 40 historic HMD populations 1751–2014.
