TABLE 1.
Summarized mortality measures of selected countries
| Country | COVID-19 raw mortality ratea (per 1 000 000 person-year) | COVID-19 age-adjusted mortality ratea,b (per 1 000 000 person-year) | Case-fatality among COVID casesa (per 100 reported cases) | All-cause excess mortalitya (based on expected number of deaths) |
| Belgium | 833 | 321 | 16.1 | 1.27 |
| UK | 581 | 272 | 14.5 | 1.37 |
| Spain | 580 | 246 | 11.1 | 1.41 |
| Italy | 568 | 195 | 14.5 | 1.28 |
| Sweden | 510 | 193 | 9.9 | 1.20 |
| France | 451 | 175 | 14.9 | 1.17 |
| United States | 358 | 209 | 5.7 | 1.23 |
| Netherlands | 355 | 156 | 12.4 | 1.23 |
| Canada | 218 | 94 | 8.2 | 1.13 |
| Germany | 105 | 40 | 4.7 | 1.04 |
| Austria | 75 | 31 | 4.0 | 1.06 |
According to the coefficient of variation, heterogeneity of between-country COVID-19 mortality data is higher than that of all-cause excess mortality. The corresponding values are 0.52 for raw mortality rate, 0.50 for age-adjusted mortality rate, 0.40 for case-fatality and 0.09 for all-cause excess mortality. This indicates that with respect to COVID-19 mortality metrics, fewer sources of heterogeneity affect all-cause excess mortality.
During the period from 02 March 2020 to 14 June 2020.
Rates were standardized (direct method) based on the age structure of the world population (source OECD data available at https://data.oecd.org/pop/population.htm).
