Excess deaths are deaths from all causes above a baseline. That baseline often represents an expected number of deaths.

Different institutions use different baselines:

Excess death calculations differ through choices of periods and baselines.

Where can I find data on excess mortality?

There many institutions collating COVID-19 surveillance deaths. There is no single source for frequent all-cause mortality.

The World Bank calculates annual crude death rate per 1,000 people for countries. The United Nations Statistics Divisions publishes annual death statistics. The latest year in these datasets is 2019.

There are two teams of researchers collating weekly and monthly mortality figures.
