* The division of the world in regions throughout this report corresponds to the statistics methodology of the Department of Economic and Social Affairs (DESA): For the purposes of the analysis, Northern Africa and Western Asia were grouped, following the UN Economic Commission for Western Asia's grouping of Arab States. Further, Central Asia was grouped with Southern Asia; Eastern Asia with South-Eastern Asia; and Oceania with Antarctica.

The UN75 team additionally analysed the data by education level, age and disability. The results were largely aligned with the global and regional findings. Where major differences were observed, such as on the question of outlook for the future, these differences were highlighted in the results.
