Facebook Adult Ad Reach Rate, As of Feb 2025

The data reveals significant discrepancies in Facebook’s reported ad reach across various global regions, with several countries exhibiting implausibly high rates exceeding their total adult populations. Western Sahara tops the list at 130.6%, followed closely by Libya (127.6%) and Mongolia (118.1%), while major markets like the Philippines and Vietnam also report statistically impossible figures above 100%. These anomalies suggest systematic issues in Facebook’s audience measurement methodology, possibly stemming from duplicate accounts, users registering with incorrect locations, technical limitations in population statistics, or algorithmic estimation errors in Facebook’s advertising platform. The pattern appears particularly pronounced in developing regions with rapidly growing digital adoption, raising questions about the reliability of Facebook’s audience metrics for advertisers targeting these markets and highlighting potential challenges in digital advertising measurement across different global contexts.
