CDC tracked millions of phones to see if Americans followed lockdown orders

I got free academic access to this dataset. The data is anonymized and aggregated to the census block level (500 people). It does not allow for the kind of tracking that the article is fear mongering about.

The average census block has a population of 30 people. Millions of census blocks have a population of zero while millions more have a population of only a couple of people. Surely it must be at the census tract level or higher?

Census block group, not census block

Whether or not that's true, the government should ban this type of business. Not support it with our tax dollars.

There is definitely data that can't be worked backwards.

Not full anonymity if you can see where the phones are moving from-to
