Since the outbreak of COVID-19 in the United States, individual states have responded with a wide range of measures to break the chain of infection and manage the broader impacts of the disease. The lack of a unified federal response in the United States places additional importance on these state-level responses. The Oxford COVID-19 Government Response Tracker’s (OxCGRT) US state-level data provides a systematic way to measure and compare government responses to COVID-19 across states from January 1, 2020 to the present, and will updated continuously going forward. We combine individual indicators into a series of novel indices that aggregate various measures of government responses. These indicators and indices can be used to describe variation in government responses, explore whether the government response affects the rate of infection, and identify correlates of more or less intense responses.
