(Source: Authors’ elaboration based on the HMD data)
Life expectancy and lifespan inequality for different inequality indicators, 1832–2020, HMD countries. A Standard deviation for females; B coefficient of variation for females; C normalized standard deviation or coefficient of variation for females; D standard deviation for males; E coefficient of variation for males; F normalized standard deviation or coefficient of variation for males. Red curve for maximal inequality given maximal lifespan = 122, black line for Japan, dark magenta line for Canada, pink line for Taiwan, grey line for Hong Kong. Normalized indices were calculated when maximal lifespan equals 122
