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

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.

Publicly Available

We are now releasing Facebook Movement Range Maps publicly. The Facebook Movement Range data is available in visualized format for 14 countries here and in csv format for a longer list of countries here.

“Besides measuring the effect that social distancing measurements have on people’s mobility -- which is presented once a week in National TV -- having access to this dataset has enabled us to detect regions that are interconnected which has given us a lot of context regarding the dynamics of the pandemic. This information has been key for us to inform the decision making process in such important times.””

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.


People who use Facebook on a mobile device have the option of providing their precise location in order to enable products like Nearby Friends and Find Wi-Fi, and get local content and ads. Movement Range Trends are produced by aggregating and de-identifying this data. Only people who opt in to Location History and background location collection are included. People with very few location pings in a day are not informative for these trends, and, therefore, we only include people whose location is observed for a meaningful period of the day. You can find a tutorial here, which will walk you through the creation of a map and dataset which identifies potential problem areas for COVID-19 vulnerable populations using two publicly available datasets produced by the Facebook Data for Good team.
