What Derek Ouyang has been doing with Placekey & SafeGraph data
Using Placekey location and SafeGraph mobility data, Derek Ouyang and his co-researchers were able to analyze how cities were able to respond to COVID-19 in U.S. cities. Peak hour visit monitoring and vaccine penetration analysis allowed them to understand how COVID impacted mobility through a data-driven lens. They can then use this to inform best practices and city-level decision making for public health and city officials, as well help manage public-private relationships.
By using SafeGraph mobility data — rich with Placekey POI data — they were able to compare movements of vaccinated and unvaccinated people and the locations they visited. This information could be used to help inform the best places to set up vaccination sites and forecast economic recovery.
