This is the data for annual death rates by age for COVID-19 (left column), Influenza (center column), and what is called by the Actuaries, All-Cause Mortality (right column). That third column is, death for any reason for a particular age group. All of these data are annual deaths per 100,000 people of the particular age group or gender (the All-Cause data is separated by gender to show how much harder it is for a guy to stay alive for a year compared to a women).
