  • Deaths with laboratory testing are deaths due to COVID-19 with:
    • A positive PCR test (confirmed case) or antigen test (probable case) for SARS-CoV-2
      AND
      • COVID-19 is listed on the death certificate
        OR
      • Clinical history/autopsy findings that provide evidence that the death is related to COVID-19 without an alternative cause (i.e. drowning, homicide, trauma, etc.).
  • All data are preliminary and may change as more information is received.
    The shaded bar at the end of graphs indicates a lag period where data may be incomplete.
  • More information is available in: COVID-19 Death Case Definitions (PDF)
    Updated 1/31/2022.
  • Population estimates are obtained from the 2010 Census Bureau Population Estimates Program (PEP) and the 2019 American Community Survey (ACS) 5-year estimates for the state of Minnesota available at United States Census Bureau: Explore Census Data.

  • Deaths are represented by the date of death unless specified otherwise. Deaths are added as they are reported and verified.
  • Total non-laboratory-confirmed COVID-19 deaths have COVID-19 listed on the death certificate, but no documented positive laboratory test for SARS-CoV-2.
    On 10/14/20, this category name was changed from “probable deaths” to "non-laboratory-confirmed COVID-19 deaths."

  • All data are preliminary, and reports require verification before counting as a death. Therefore, the data may change and reports for the most recent weeks may more dramatically undercount the total number of deaths occurring in that week. We continuously receive death reports and work to confirm, process, and report them as quickly as possible.
  • For some deaths, sex, race/ethnicity, or age data may not be available and therefore are excluded from an analysis. This means that the total number of cases for each of the charts below may vary slightly.
  • Most of the graphs on this page show COVID-19 death rates rather than death counts. It is important to use death rates when making comparisons between groups that have different population sizes. For example, the White population is much larger than the Native American/Alaska Native population in Minnesota so we would expect to see much higher death counts among White Minnesotans. In order to compare whether one of these two groups is being disproportionately impacted by COVID-19, we must calculate the rate, which is the number of deaths divided by the population size. Count data is still available and can be found in the CSV files that accompany each graph.
  • Age adjustment for age-adjusted rates is performed when you want to make comparisons between groups with different age distributions. It is important to note, that age-adjusted rates are not the actual rate of disease occurring in the state. The crude rate is the actual rate among a population in the state of Minnesota and is a result of many factors, including age, race/ethnicity, gender, and other factors we are unable to measure.
    • For example, in Minnesota women are on average older than men. Because age is associated with a higher rate of severe infection and death due to COVID-19, the rate of hospitalization and death in women in Minnesota might be higher because women are older. If we want to understand whether a woman is at higher risk of hospitalization or death compared to a man of the same age, we use age adjustment to remove the effect of age in the population to make a more direct comparison by sex. The same process can be used to compare different groups by race/ethnicity or other factors.
  • Data for the most recent MMWR week will only contain information for Sunday through Tuesday based on when the data are compiled to create these graphs.

Deaths Over Time (7-day Moving Average)

  • Download: 7-day Moving Average of Deaths (CSV)

  • Deaths over time are shown using a 7-day moving average of the daily count of all deaths and the statewide daily death rate.
    • To get the 7-day moving average for deaths, we add all the deaths from the previous 7-days (including the current date) and then divide by 7.
    • To get the 7-day moving average for deaths rates, we add all the rates (number of deaths divided by the total Minnesota population, multiplied by 100,000) from the previous 7 days (including the current date) and divide by 7.
  • A 7-day moving average provides a more useful representation of the data by smoothing out any short-term spikes or dips that occur across a week because of external factors not related to disease transmission, such as a facility not being open on certain days or delays in data reporting.
Total deaths (cumulative) 13,285
Total non-laboratory-confirmed COVID-19 deaths (death certificate) (cumulative) 366

Deaths by County of Residence

  • Download: Deaths by County of Residence (CSV)

  • County rates are calculated using confirmed COVID-19 deaths by reported county of residence by week of death divided by the total county population. The rate is then multiplied by 100,000.
  • Weeks are defined as Sunday through Saturday. Therefore "Last Week" corresponds with the Sunday through Saturday of the week prior to when the data are posted.

Demographics

Mortality Rate by Age Group

  • Download: Mortality Rate by Age Group (CSV)

  • Rates are calculated using confirmed COVID-19 deaths by reported age at date of specimen collection divided by the age-specific Minnesota population. The rate is then multiplied by 100,000.
  • The “total” rate line is the total of all deaths in this graph (for whom age is available) divided by the Minnesota population, obtained by adding together the total population for each age group. The rate is then multiplied by 100,000.

Mortality Rate by Sex

  • Download: Mortality Rate by Sex (CSV)

  • Rates are calculated using confirmed COVID-19 deaths by reported sex at date of specimen collection divided by the total sex-specific Minnesota population. The rate is then multiplied by 100,000.
  • The “total” rate line is the total of all deaths in this graph (for whom sex data is available) divided by the Minnesota population. The rate is then multiplied by 100,000.
  • The age-adjusted rates per 100,000 are obtained by taking the incidence rate per 100,000 (as described above) for all deaths for whom sex data is available and standardizing to the U.S. 2000 Standard Population which can be obtained from the National Cancer Institute: Standard Populations (Millions) for Age-Adjustment.

Mortality Rate by Race/Ethnicity

  • Download: Mortality Rate by Race and Ethnicity (CSV)

  • Rates are calculated using confirmed COVID-19 deaths by reported race/ethnicity at date of specimen collection divided by the total Minnesota population for each race/ethnicity. The rate is then multiplied by 100,000.
  • The “total” rate line is the total of all deaths in this graph (for whom race and ethnicity data is available) divided by the Minnesota population. The rate is then multiplied by 100,000.
  • The age-adjusted rates per 100,000 are obtained by taking the incidence rate per 100,000 (as described above) for all deaths for whom race and ethnicity data is available and standardizing to the U.S. 2000 Standard Population which can be obtained from the National Cancer Institute: Standard Populations (Millions) for Age-Adjustment.
