Coronavirus City and County Non-Pharmaceutical Intervention Rollout Date Dataset

Coronavirus Infections NPI Dataset Keystone
Coronavirus Infections NPI Dataset Keystone

Insufficient data has complicated the rollout of Coronavirus (COVID-19) “Non-Pharmaceutical Interventions” (NPIs) such as the closing of schools. Keystone has partnered with Susan Athey, Stanford Professor of Economics, and Marco Iansiti, Director of Harvard Business School’s Digital Initiative, to estimate the effectiveness of NPIs as a guide to policymakers, and to aid firms in developing strategic responses, respectively. We are building a comprehensive, highly localized and freely available data set of city, county and state rollout dates for NPIs. For more information or data access, contact us!
