A dashboard provides index of people staying at home amid CoVID-19

For the first time in the history of human civilization, the entire world has stopped to limit the spread of novel coronavirus. Countries have ordered people to stay at home; schools, colleges, shopping complexes, offices, etc. are locked so that people do not get in touch with each other. This social distancing has helped a lot in limiting the spread of the virus.

In order to check people’s mobility behavior and how much are they are staying at home and are going outside, SafeGraph has built an innovative dashboard “Shelter in Place Index: The Impact of Coronavirus on Human Movement”.  This dashboard visualizes people’s mobility behavior during the lockdown, showing the percent of people staying home all day and the amount of time they spend outside. The interesting thing about the dashboard is that it is not based on units of distance travelled. Instead, it shows every movement of people, whether they visit a neighbor or to the grocery store. Whether the distance traveled is 10 miles or 0.1 miles, all “away-from-home” events are classified the same in this dashboard.

The matric provided by the Shelter in Place Index is valuable. One does not need to travel long distances to destabilize social-distancing and enable viral transmission. This dashboard also enables better comparisons between rural, suburban, and urban areas, even though the former generally travel greater distances for essential activities like grocery shopping.

What is Shelter in Place Index?

Powered by SafeGraph Social Distancing Metrics, Shelter in Place Index aggregates and provide privacy-safe summary of time spent by people at home and away from “home” each day, for every state and county in the USA.

By “home” the dashboard refers to the most common night time location in recent months identified to a precision of about 100 square meters. Social Distancing Metrics is built from an anonymized population movement dataset representing 45 million smartphone devices provided by Veraset, and is representative of the US population.

This free to use dashboard represents the change in the % of people staying home compared to baseline. The index spans -100% to 100%, where 0 is no change from baseline. Baseline is defined here as the average percent of people staying home each day across the seven days ending February 12, 2020.

How does the dashboard work?

Shelter in Place Index is very easy to use dashboard. There is a slider on top of the map that represents the time from February 1, 2020, to till date. So anyone can slide the bar and select the time frame. There is three option on top of it from where one can choose shelter in place index and percentage staying home. Then comes the region where there is all location of the United States and see the percentage of people staying at home or stepping out of the home. One can also choose to see state-wise and country-wise data. Shelter in Place Index is free for academics, non-profits, and governments.

This dashboard is built on MapBox and Open street Map and allows anyone to update it and Data in the dashboard is updated daily.
