The data labeled GSDI was originally gathered by Google.
It can be downloaded from https://www.gstatic.com/covid19/mobility/Global_Mobility_Report.csv

## Data Processing

The GSDI is calculated as the average of the categories `workplaces`, `retail and recreation` and `transit stations`. When one or two of these are missing, the average of the remaining was calculated.
