Replication Data for: Quantifying human mobility behavior changes during the COVID-19 outbreak in the United States

This study aims at quantifying human mobility behavior changes during the COVID-19 outbreak in the United States. We developed the Social Distancing Index (SDI) to evaluate people’s mobility pattern changes along with the spread of COVID-19 at different geographic levels. The SDI scores are based on the five basic mobility metrics derived from mobile device location data.
