The underlying data is captured from the sections of the websites of each retailer, and is refreshed once a day at the time indicated on the dashboard. It is assumed that each retailer accurately maintains the stock availability status of products on its website. The ZIP codes covered have been selected based on the primary clusters of COVID-19 proliferation in the U.S., as well as standard population densities. The nearest store in the vicinity of the displayed ZIP code has been considered for each retailer. The dashboard will consistently be updated with more data, covering newer ZIP codes as well as retailers.
