If you use household survey data and now include within-national inequalities too, global inequality is unchanged between 2018 and 2023 (green dots). The distance between the green dots and the blue line gives the overall importance of within-national inequalities: about 15 Gini points out of 60. These are all incomes in PPP terms; if one used market exchange rates, global Gini would be 70. There is no country in the world with such high inequality.

Unweighted international inequality (calculated using all countries' GDPs per capita without taking population size into account) is stable since 2018 (red line). If you still use GDP per capita but give to each number a weight proportional to country's population, international inequality is going down (by a little; blue line).
