A Gini coefficients of the past (1970–2010) and projected (2015–2100, under five SSPs) HDI between countries (GHDI). B The same as (A) except showing Gini coefficients of the three HDI indicators, respectively (GHealth, GEducation, and GIncome). Note that because the income indicator’s plausible range is much broader than that of the health, the values of the three Gini coefficients are incomparable. In addition, the Gini coefficients we presented here are based on between-country differences and neglect the within-country differences. C A contrast of the potential well-being outcomes of the 161 countries in 2100 under a “best” scenario (SSP1, top) and a “worst” scenario (SSP3, bottom).
