Figure 5.

Number of years gained (in conditional life expectancy compared to 20 years before) due to rectangularization (top panels) and to longevity increase (middle panels), based on indexes R and t_Qwith t₀ = 50 and Q = 0.9, estimated from life tables by year of death (period) for cohorts of men (left panels) and women (right panels) born in Switzerland between 1876 and 2006. The dotted lines in the bottom panels show the percentage of this gain attributable to rectangularization (LEAR). Smoothing splines have been added to show the trends (solid lines).
