Analysis

As shown in Table 1 below, the death rate due to stroke has declined since 2006, and it is now the sixth-leading cause of death in Minnesota. As recently as 2010, it was the third-leading cause of death in the state, but has fallen below Accidental Injury and Alzheimer’s Disease, both of which have rising death rates. In addition, COVID-19 became the third-leading cause of death in 2020. The age-adjusted death rate for stroke for men and women is similar. More women die of stroke than men, but usually at an older age, which explains the similar death rate. Total stroke deaths were lowest in 2009 and have risen slightly in the years since. Chart 1 shows the pattern in total number of deaths and for women (green) and men (blue) since 2006. Even though the number of deaths has increased slightly, death rates have remained relatively stable. This can be explained by our aging population, with the number of older people who are at a risk of dying from stroke also increasing each year.

Despite Minnesota’s overall lower stroke death rate compared to the United States (17% lower in 2020), there are large disparities in the state. As shown in Chart 2 and Table 2, the death rate due to stroke is highest in Asian/Pacific Islander, African-American/African Born, and American Indian communities in Minnesota and lowest in Latinx/Hispanic communities. The last column of Table 2 shows a rate ratio, which compares two rates to describe how much one group is impacted compared to another. Any number larger than 1 means that the group of interest is higher than the comparison group. Any number smaller than 1 means the group of interest is lower than the comparison group. Asians/Pacific Islander, African American/African Born, and American Indian Minnesotans die from stroke at rates approximately 40% higher than Minnesotans overall. Stroke death rates for Latinx/Hispanic Minnesotans are 50% lower than the Minnesota average. These disparities in deaths are rooted in historical inequities that have persisted in the United States and Minnesota for many years.

African-American/African Born	393	44.6	1.37
American Indian	102	44.5	1.37
Asian/Pacific Islander	339	45.6	1.40
Hispanic	85	16.2	0.50

The number of deaths due to stroke increases in older age groups. Table 3 shows the number of deaths and death rate due to stroke over the three most recent five-year time periods. Over that 15 year period, the largest declines in death rates have been for Minnesotans ages 35-44 and 65 and older, as shown in Chart 3. For Minnesotans ages 45-54 there has been virtually no changes in death rates, while for Minnesotans ages 55-64, death rates have increased by more than 10%.
