Parents have to protect their children against both COVID and reckless politicians. New maps highlight areas where COVID cases are accelerating.
Large amounts of data that's updated regularly can be overwhelming. How do you make sense of it quickly to make better decisions? Use a good map.
There are large amounts of data about COVID-19 infections, hospitalizations and deaths. New numbers are collected from hospitals and clinics every data. Colored maps are good, but often hide the clarity that people need to make better decisions. Looking at COVID data on a weekly basis rather than a daily basis provides more perspective on trends and make it easier to answer questions such as:
- Are COVID-19 cases going up or down week to week?
- Is the number of cases accelerating or decelerating?
- Where are new case rates significantly higher?
Cartography is all about conveying information through maps. Charlie Frye and Jim Herries are two master cartographers at esri who have developed an innovative approach to present COVID data using arrows of different sizes and colors. I've applied their approach and data from the John Hopkins Coronavirus Resource Center to show the COVID danger level in school districts based on their county.
Purple arrows show cases going up while orange arrows show cases going down.
Bigger arrows indicate where new case rates are significantly higher.
Scan the map for the size, color and direction of arrows for the dangerous areas.

The map is dynamic and will change automatically as new COVID data is released.
Clear and present danger
Notice the large, purple arrows in Miami, Coral Springs, West Palm Beach, Orlando, St. Petersburg and Tallahassee. These areas are bad and getting worse.
Maps make data usable
Most people are comfortable using maps to get directions and information on destinations. Maps are ideal for conveying a large amount of data with an easy-to-use interface. This StoryMap includes data on both COVID cases and trends along with school district boundaries which become visible as you zoom into the map. This short tutorial is included to give readers tips on how to use the map and understand the legend.
Data for COVID safety
The John Hopkins Coronavirus Resource Center provides an excellent dashboard that shows the number of COVID cases and deaths per county. This map shows the number of COVID cases in a county, but does not reveal where the number of COVID cases is accelerating and for how long has that acceleration been taking place. It is also hard to gauge the COVID infection rate across two counties with vastly different number of residents.
"In Florida, hospitalizations are now catching up after a month of increasing cases. The state had 10,207 people hospitalized with confirmed COVID-19 yesterday, the highest number the state has reported since the pandemic began, according to the Associated Press. Florida is now leading the nation in per capita hospitalizations for COVID-19. Despite the rise in case activity, Florida Gov. Ron DeSantis signed an executive order this weekend banning schools from issuing mask mandates." - Center For Infectious Disease Research and Policy
"Florida, Texas schools defy governors' bans on mask mandates as COVID cases soar. School districts in Florida and Texas are bucking their Republican governors' bans on requiring masks for children and teachers as coronavirus cases soar in conservative areas with low vaccination rates. In Dallas, where some staff had threatened to quit if masks were not mandated to protect children, teachers and others, school district officials said they did not believe the governor's order should be applied to them. Schools in Austin also plan to require masks." - Reuters
