US: Kansas and other states track lockdown compliance via Unacast analytics
The Department of Health in the US state of Kansas is tracking residents' locations via a platform called Unacast, which compares aggregated GPS mobile phone data from before and after the implementation of social distancing and grades each county on its compliance. As of April 1, 45 of 105 Kansas counties had received an F rating, and the state as a whole had managed a C. Unacast says the data it has access to is updated every other day and publishes updated ratings on all 50 US states. Vermont is highest-ranked, at B+; North Carolina is ranked lowest, at D-. Kansas is the first state to acknowledge using the platform.
