Movement Range Maps
Movement Range Maps inform researchers and public health experts about how populations are responding to physical distancing measures. These datasets have two different metrics: Change in Movement and Stay Put. The Change in Movement metric looks at how much people are moving around and compares it to a baseline period that predates most social distancing measures. The Stay Put metric looks at the fraction of the population that appears to stay within a small area surrounding their home for an entire day.
Differential privacy minimizes risk of re-identification of individual data with the help of possible additional information — even information we cannot anticipate now. Applying a DP framework takes into account the sensitivity of the data set and adds noise proportionally to ensure that with high probability no one can re-identify users.
This data is updated daily. Each metric in this data set is produced for a given administrative region once per day.
Who Uses Movement Range Maps
Researchers from around the world at schools like the Harvard School of Public Health, National TsingHua University, or the University of Venice use Movement Range data to understand how populations are responding to physical distancing measures.
Public health experts
Public health experts can use Movement Range data to assess non-pharmaceutical interventions and other policies meant to reduce the rate of coronavirus transmission.
Nonprofits and NGOS
Nonprofits like Direct Relief analyze change in movement treadlines that have become part of daily situational reports for policymakers.
