Background: To determine the impacts of statewide coronavirus disease 2019 (COVID-19)-related public health and social measures (PHSMs) and attempted pandemic mitigation measures on years of potential life lost (YPLL).
Methods: The "openness score" of each state during the COVID-19 pandemic was obtained using two open-source sites, the Multistate openness score and the Wallethub openness score. These scores combined various PHSMs, such as restrictions on gatherings and closing various types of businesses.
