I’ve been maintaining covdata, an R package with a variety of COVID-related datasets in it. That means I’ve been pulling down updated files from various sources every couple of days. Most of these files are at static locations. While their internal structure may change occasionally, and maybe they’ve moved once or twice at most since I started looking at them, they’re generally at a stable location. Apple’s Mobility Data is an exception.
Every day begins in the same way. I get up. I make my coffee. I look at the data. Everything about this is absurd. To begin with, there’s the absurdity that everyone with a job like mine faces each day. Locked down at home with the kids, trying to get things done, unable to properly teach, write, or think. The household is like a little spacecraft, drifting in the void. Occasionally you venture outside to get supplies, or to check the shields.

My post about Apple’s mobility data from a few days ago has been doing the rounds. (People have been very kind.) Unsurprisingly, one of the most thoughtful responses came from Dr. Drang, who wrote up a great discussion about the importance of choosing the right baseline if you’re going to be indexing change with respect to some time. His discussion of Small Multiples and Normalization is really worth your while.

I’ve added a GitHub repository containing the code needed to reproduce the graphs in this post, as what’s shown here isn’t self-contained.
Apple recently released a batch of mobility data in connection with the COVID-19 pandemic. The data is aggregated from requests for directions in Apple Maps and is provided at the level of whole countries and also for a selection of large cities around the world. I folded the dataset into the covdata package for R that I’ve been updating, as I plan to use it this Fall in a course I’ll be teaching.
