a, Germany; b, Japan; c, United States. a–c, Standardized median ages based on country-specific life tables for 2000. d, Standardized median ages based on Japanese life table for 2000. The values through to 2000 are observed; later values are medians based on 1,000 simulations (for 95% prediction intervals see Supplementary Table 1). All values are based on period life tables.
