The EuroMOMO monitoring system is based on national mortality data registered in the 26 countries or subnational regions participating in the EuroMOMO network.

For most countries, the full national population mortality is covered. However, in a few countries, only a proportion of the country’s mortality is included, as shown in the table below.

The covered population mortality in the network is at the moment approximately 420 million people, as of 1 January 2021.
