Database of state policy actions including states of emergency, closures, re-openings, re-closures, stay at home and shelter-in-place orders, mask requirements, quarantine rules, alcohol and firearm restrictions, housing protections, unemployment policies, changes to Medicaid and SNAP, racial disparities, incarceration, substance use disorder policies, relevant state policies that were in place before COVID (for example those relating to Medicaid expansions), state characteristics (such as population and 2018 all-cause mortality), vaccination, and other responses to the COVID-19 pandemic. All policies included are binding directives/mandates (ie the data does not include guidelines or recommendations that are required) and the dataset only includes policies effective at the state level, not the actions of local governments.
