Michigan’s Urban Core Continues to Experience Highest COVID Numbers

The total number of COVID cases in Michigan increased to 28,059 (Chart 1), which was equivalent to 281 cases per 100,000 people (Chart 2) on April 15. Of those total COVID cases, the City of Detroit had 7,236 cases, Oakland County had 5,576 cases, Wayne County (excluding Detroit) had 5,408 cases and Macomb County had 3,792 cases (Chart 3).  The number of confirmed cases in Washtenaw, Livingston, Monroe and St. Clair counties combined totaled 1,484, with Washtenaw County accounting for 798 of those cases,  according to the most recent data from the State.

The daily data highlighted in these posts is from Michigan.gov/coronavirus, where data is updated daily at 3 p.m. Historical data was supplied from covidtracking.com, which republishes COVID data from the State.

In Chart 4 we see that the City of Detroit has consistently had the highest number of COVID cases per 100,000 people, which was a rate of 1,061 on April 15. Oakland County had the second highest rate at 829 cases per 100,000 people and Wayne County (excluding Detroit) had 804 cases. Macomb County had 564 COVID cases per 100,000 people. When looking at Chart 4 we also see that there were per capita increases for every county between April 14 and April 15, but Macomb County had the highest increase in the number of COVID cases per 100,000 people at 32. In Wayne County the rate increased by 30, and it increased by 20 COVID cases per 100,000 people in Detroit between April 14 and April 15.

Chart 5 shows that Detroit, Macomb, Oakland, Wayne and Washtenaw counties experienced decreases in the number of new COVID cases between April 14 and April 15. On April 15, Oakland County reported the highest number of new COVID cases at 212. Wayne County had 203 new cases, Macomb County had 172 and Detroit had 132.

When looking at new COVID cases on a per capita basis, the data shows that Detroit and Macomb County now have the highest rates (Chart 6). According to the data, on April 15 both Detroit and Macomb County had 20 new COVID cases per 100,000 people; Wayne County had 19 and Oakland County had 17.  These four areas had nearly double the number of new COVID cases per capita as those more rural counties in the region (Washtenaw, St. Clair, Monroe and Livingston).

In addition to the raw data of confirmed cases, we also show the percent change in the number of cases reported day-to-day. On April 15 the percent change from April 14 was 3.92 percent, a decrease from the day’s prior change of 5 percent.

Originally, we were reporting the day-to-day percent change in the number of cases from March 16. However, there was a spike in the number of tests available early on that made this data set also spike (on March 18 the day-to-day percent change as 320%). We have now started showing percent change data from March 21 forward to allow readers a more precise visual. If you would like to see the earlier versions of this data set please review our earlier posts. 

It was reported by the State of Michigan that on April 14 the total of COVID-19 deaths reached 1,921. This was a percent change of 8.6 percent from April 15, which was a decrease from the 10.4 percent increase of the day prior (Chart 9). The 1,921 total deaths reported for April 15 was 153 deaths higher than what was reported on April 14 (Chart 10). The new deaths reported on April 15 was a decrease from the 166 new deaths reported on April 14.

Of the total deaths reported, Detroit continues to make up the majority of them. On April 15, the Michigan Department of Health and Human Services reported 475 total deaths in Detroit-the highest total number of deaths in one city or county in the state. However, also on April 15 Wayne County, excluding Detroit, broke 400-the county now has 409 COVID deaths. Additionally, there were 392 deaths in Oakland County and 332 deaths in Macomb County (Chart 11).

On a per capita basis, per 100,000 people, Detroit also continues to have the highest number of deaths per 100,000 people at 71 (Chart 12). On April 15 Wayne County had 61 COVID deaths per 100,000 people, Oakland County had 58 and Macomb County had 49.

At 48 Detroit had the highest number of new COVID deaths on April 15, and Macomb County had the second highest at 37. Wayne County continued to experience a decrease; it reported 16 new COVID deaths on April 15.

COVID deaths in Michigan continue to rise and the data is showing that some areas, such as Macomb County, are now reporting higher daily new cases and deaths. This shows that the virus continues to spread from the urban core-Detroit-and outward. The data also reflects that the more rural counties in the region are experiencing much lower case and death numbers. However, the risk of spread is still very real which is why everyone must remain home.
