The Stanford Social Distancing project shows the dates and types of social distancing policies implemented at the county level across the United States during the beginning of the COVID-19 pandemic from volunteer survey. It includes measures such as school closures, public event cancellations, restrictions on business operations, and stay-at-home orders. Each policy entry is linked to a source document (e.g., news article or government order), and the dataset tracks these interventions' timing and geographic variation. The information is structured to allow comparison across counties and over time.
