From: Global, regional and national burden of HIV/AIDS among individuals aged 15-79 from 1990 to 2021
Absolute inequality in HIV/AIDS burden quadrupled from 1990 to 2021 while relative inequality persisted among lower-income countries. Note: The top panels display the slope index of inequality (SII), which measures absolute differences in DALYs across countries ranked by SDI, with steeper slopes indicating greater absolute inequality. The bottom panels present the concentration index (negative values indicate the concentration of disease burden in disadvantaged populations) and Lorenz curves that illustrate the distribution of DALYs relative to the population distribution by socioeconomic status
