Extended Data Figure 4: Rate of change in survival since 1900 (or the earliest year for which data was available) to a given age as a function of that age in 40 countries and territories.

From: Evidence for a limit to human lifespan

Extended Data Figure 4

The rate of change is the slope of the line calculated by an exponential regression, that is, b in the equation y = a + bx, where x is age and y is the logarithm of the number of survivors to that age per 100,000. Including France, 90% (37/41) of the regions examined exhibited the pattern depicted in Fig. 1c.
