The following article provides an overview of covid-19 mortality per country.
A) Excess Mortality Per Country
The following live chart, developed by Ariel Karlinsky and Dmitry Kobak, shows excess mortality per country, compared to the 2015-19 baseline, since the beginning of the pandemic. In most Western countries, the covid pandemic increased mortality by about 5% to 20% until March 2021, but in some Latin American countries, mortality increased by up to 100%.
These figures refer to all-cause excess mortality and may include non-covid excess deaths. Official data from the US and the UK indicate that in some countries, up to one third of all excess deaths may not be due to covid, but due to indirect effects of the pandemic and lockdowns.
Please enlarge the chart to see details. The red number indicates excess deaths since the start of the pandemic; the black number indicates excess deaths per 100,000 population; the grey number, excess deaths compared to annual baseline; the blue number, ratio of excess deaths to reported covid-19 deaths (i.e. undercounting or non-covid excess deaths). Red line is 2020, purple is 2021.
Excess mortality per country since the beginning of the pandemic (Karlinsky & Kobak)
Covid mortality depends on the infected population proportion as well as on demographics (e.g. age structure) and health indicators (e.g. cardiovascular disease prevalence). By the end of 2020, infection attack rates ranged between 10% and 30% in most Western countries and between 25% and 50% in many Latin American countries. The following chart shows the infection attack rate per country as of 1 September 2020, i.e. prior to the second wave.

Life expectancy is a theoretical concept describing the average age people born in a certain year will reach, assuming that the mortality rate per age of that year will stay constant forever.
