Through Sampling bias

This data reflects entire populations and does not adjust for age-specific risk. According to U.S. CDC data, COVID-19 has had markedly different impacts across demographics, with factors such as pre-existing conditions, socioeconomic status, and urban versus rural residency influencing outcomes. For example, the CDC reported that as 27 April 2021, the reported case fatality ratios were 0.015%, 0.15%, 2.3%, and 17% for the age groups 0–17, 18–49, 50–74, and 75 or over, respectively. Similar patterns were observed in other countries, with older populations consistently experiencing higher mortality, emphasizing the critical role of age distribution in pandemic modeling.

Data reliability

Variation between testing programmes worldwide results in different ascertainment rates per country: not every SARS-CoV-2 infection, nor every COVID-19-related death, will be identified. Additionally, testing availability, public compliance with testing, and differences in healthcare infrastructure further complicate accurate reporting. Some deaths may be wrongly attributed to COVID-19 (for example if all suspected COVID-19 deaths are counted as COVID-19 deaths, for example, Belgium counted suspected deaths as confirmed cases in September 2020, and Public Health England initially counted all deaths after a positive test "to be sure not to underestimate the number of COVID-19 related deaths", while Scotland reported all deaths within 28 days of such a positive test). Therefore, according to WHO analyses, the true numbers of infections and deaths are expected to exceed the confirmed numbers everywhere, though the extent will vary by country. These statistics are therefore less suitable for between-country comparisons. As deaths are easier to identify than infections (which are regularly asymptomatic), the true case fatality rate (CFR) is likely lower than the observed CFR. Underreporting is especially severe in countries with limited healthcare access or conflict zones, where both testing and vital registration systems are incomplete.

Reports from Socialstyrelsen in Sweden indicate 20,797 cases of Covid-19 deaths as of 2024-10-15 which differs from the table below.

Causes of variation in true CFRs between countries, include variations in age and overall health of the population, medical care, and classification of deaths. For instance, countries with higher prevalence of comorbidities such as diabetes, obesity, or cardiovascular disease often experienced elevated mortality rates even among younger age groups.

Excess mortality provides a broader estimate of these numbers. According to WHO, it includes both "direct COVID-19 and indirect, non-COVID-19 deaths". They compare overall mortality with that of previous years, and as such also include the potentially vast number of deaths among people with unconfirmed COVID-19. These statistics have been crucial for understanding the broader societal impact of the pandemic, including deaths due to delayed healthcare, mental health crises, and economic stressors.
