In Georgia, 4,080,204 people commute between 5,533 neighborhoods (defined by census block group boundaries). A neighborhood that connects to many other neighborhoods with many incoming or outgoing commuters has an elevated chance of exposure to the virus. This can be seen in two ways: either for residents who travel home at night from many places (left, 🏠-->🏢) or who are near an influx of workers who have arrived from a variety of home locations (right, 🏢-->🏠). Some neighborhoods attract workers from over 4,000 different neighborhoods (e.g., downtown Atlanta). Some neighborhoods send workers to over 1,000 neighborhoods (e.g., Campbellton). While not everyone can work from home, trying to do so can reduce trips, and thus, exposure, in critical neighborhoods.
