From: A set of indicators for decomposing the secular increase of life expectancy
Evolution of rectangularity index R (top panels) and longevity index t Q (middle panels), using t 0 = 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. Bottom panels show the evolution of conditional life expectancy (for those persons reaching t 0 and dying before t Q ) during that period.
