⚖️ WHO vs Government Data Comparison
Understanding Data Discrepancies
Government-reported health statistics often differ from WHO/independent estimates due to:
methodology differences, political motivations, data collection capacity,
and definition variations. Below are notable discrepancies.

Excess mortality is key metric. Compares deaths to expected baseline regardless of cause coding.
Low-income countries undercount. Only 1/3 of deaths are registered in Africa.
WHO uses modeling. Estimates fill gaps using statistical models when data missing.
Nordic countries most accurate. Strong civil registration, transparent reporting systems.
