In a similar fashion we are entering into severe weather season here in the
South are meteorologists are reporting on blogs and videos that their model
data is not near as good because the resolution is not where it usually is
because no commercial airlines are flying and apparently providing this model
data.
Similar story I guess....

Most people have not turned off their location services on their smart phones.
There are plenty of background programs that are already embedded in various
apps people use. Geotagged Twitter data has user ID’s attached to it, Google
tracks most movements and of course records and stares all the voices that
people use when using the microphone for voice to text etc. Facebook checkin’s
etc. are also part of the mix of data sources. In the rural areas for these
shorter periods of time they are looking at I am not sure how much sampling
they get compared to more densely populated regions. Here are some articles on
the topic:

Location based data has been available for a while, most of it is supposed to
be anonymized but you can still glean off a lot of useful information with the
information. Some of these studies have been put together quite quickly so the
methodology I see in questions. For instance I see no mention of the makeup of
the workforce for any given regions. In my area a better than 50% of the
population could easily be in the essential workforce category being that
healthcare and the service industry are a majority of the employment. Those
people are still going to work. Also if you look at the break down of things
like their letter grades they give to regions the percentages from say a to C
are very minor and I think that is just to cause more sensationalized results.
When a 50% reduction in travel is noticed, I would not consider that a D grade
in a rural area. They are just using numbers from pre and post stay at home
orders to grade society. Thank you,Brian Websterwww.wirelessmapping.com

Our local underground facilities location agency says locates are way up. They
think people are doing lots of home projects.

Opinion: not very useful. Rural people drive farther to work or shop, that
doesn’t mean they interact with more people. I may drive 50 miles to drop off
radios for my tech to install but not interact with a single person. I saw one
analysis that blamed it on Walmart for driving all the local stores out of
business so people in some areas have to drive 20 miles to buy groceries or buy
supplies. But again, what matters is probably how crowded that Walmart is and
whether you practice distancing while shopping, not how far you drive to get
there. I imagine anonymized cellphone geolocation data is available for this
purpose, either from what celltowers you are near, or browser and app data.

I've seen a bunch of articles based on "data" put out by Unacast regarding
geographies that are better or worse at social distancing.
They're using travel distance to determine who's good and who's bad.
Is their data worth a shit? You could put 10k phones into 10k cars and drive
them in circles all day and your reported metric would be through the roof, yet
there was nearly zero additional risk because people were separated.
How are they collecting this data? On whose behalf? With what permission?
The only useful data would perhaps be in detecting the change in number of
visible Bluetooth devices from January to now.
