Median absolute difference (in percentage points) between UMD-CTIS and UN population (2020) across all age groups. Note: Final sample includes 83 countries countries/territories (Appendix Table 1). For each country and each age group, the absolute difference in percentage points between UMD-CTIS and UN population estimates for 2020 is computed as Dgc = |Pgc,UMD-CTIS survey - Pgc,UNpop|, where Pgc is the percentage in age group g for country (c). The median absolute difference across all age groups is reported in the map. Age groups are defined in the methods section
