On March 29, Google published the latest series of reports, detailing the policy impact on personal mobility in the U.S. According to Google, “These reports show how visits and length of stay at different places change compared to a baseline.” I aggregated the numbers to get a more general picture of the policy impact by State. The winner are the residents of HAWAII who made the most significant changes according to Google’s numbers.

How have visits and length of stay at the workplace changed compared to the five weeks Jan 3–Feb 6, 2020? Hawaii shows the most significant decrease compared to its baseline in January. While residents and travelers to profoundly impacted states like California, New Jersey, and New York reduced their workplace-related mobility by over 30 percent, Louisiana seems to fall behind.

The transit related changes are even more pronounced. While Hawaii is leading the list, New York and New Jersey are ranking fourth and fifth among all states. Nebraska shows only slightly reduced values.

The field is split when it comes to Park related stays and mobility. We see a similar ranking with Hawaii at the top and Ohio, Nebraska, Missouri, Kansas, and Kentucky at the bottom. While the states at the top show significant decreases, people in states like Ohio and Nebraska increased their Park related mobility.

Mobility and stays in residential areas increased. The changes are still modest between 10 and 20 percent.

People spend slightly less time at Grocery and Pharma places.

The data shows a similar picture for Retail and Recreation areas.

And finally, all U.S. States ranked by their aggregated Google COVID19 Mobility values.
