After adding over 295,000 new cases throughout the last week, the U.S. now has more than 78.6 million confirmed cases of COVID-19. There have been more than 950,000 COVID-19-related deaths — the highest death toll of any country.
New cases continue to rise, albeit at a slowing rate. In the past week, there were an average of 15.4 daily new coronavirus cases per 100,000 Americans — a decrease from the week prior, when there were an average of 22.6 daily new coronavirus cases per 100,000 people.
While COVID-19 has spread to nearly every part of the country, cities continue to be the sites of major outbreaks. Experts agree that the virus is more likely to spread in group settings where large numbers of people routinely have close contact with one another, such as colleges, nursing homes, bars, and restaurants. Metropolitan areas with a high degree of connectivity between neighborhoods and a large population may be particularly at-risk.
The Kansas City, MO-KS, metro area consists of Jackson County, Johnson County, Clay County, and 11 other counties. In the past week, there were an average of 12.4 new coronavirus cases every day per 100,000 Kansas City residents, in line with the national figure. The metro area’s average daily case growth in the most recent week is a decrease from the week prior, when there was an average of 18.9 daily new cases per 100,000 Kansas City residents.
The spread of coronavirus depends on a variety of factors and can vary even between neighboring counties. Within the Kansas City metro area, COVID-19 is growing the fastest in Ray County. There were an average of 24.7 new cases per day per 100,000 residents in Ray County during the past week, the most of the 14 counties in Kansas City with available data.
Case growth in the Kansas City metro area varies widely at the county level. In Lafayette County, for example, there were an average of 2.1 new cases per day per 100,000 residents in the past week — the least of any county in Kansas City and far more than the case growth rate in Ray County.
While Ray County is driving the growth of COVID-19 in the Kansas City area, it does not have the highest incidence of cases overall. As of March 10, there were a total of 22,417.5 confirmed cases per 100,000 residents in Ray County, the 11th most of the 14 counties in the metro area. For comparison, the U.S. has so far reported 24,221.8 cases per 100,000 Americans nationwide.
The pandemic has led to the closure of thousands of consumer-facing businesses around the country. These changes have led to widespread job loss and record unemployment. In Ray County, unemployment peaked at 15.2% in April 2020. As of June 2021, the county’s unemployment rate was 9.4%.
To determine the county in every metropolitan area where COVID-19 is growing the fastest, 24/7 Wall St. compiled and reviewed data from state and local health departments. We ranked counties according to the average number of new daily COVID-19 cases per 100,000 residents in the seven days ending March 10. To estimate the incidence of COVID-19 at the metropolitan level, we aggregated data up from the county level using boundary definitions from the U.S. Census Bureau. Population data used to adjust case and death totals came from the U.S. Census Bureau’s 2019 American Community Survey and are five-year estimates. Unemployment data is from the Bureau of Labor Statistics and is not seasonally adjusted.
