All I could glean from the abstract is that people walk more in walkable cities.

I'm confused. Usually a "natural experiment" is a chance event that affects some random subset of a population. Here, they seem to be using "natural experiment" to refer to the event that someone decides to move to a different city. But obviously the subset of people in Amarilllo, TX who decide to move to New York, NY are going to be somewhat different than the subset who don't. So isn't this confounded?
It's really strange that they just jump into the paper and keep saying "natural experiment" over and over again without any justification that they actually have one. They do eventually get to this in the "Selection effects in relocation and mobile app usage" section, but I think they really downplay the seriousness of the issue.

This is broken at the top and bottom. Your elected representatives don't know that a bicycle network even exists. Safer roads for cars are their only transportation priority.

I’d like to see a study like this for young kids. Anecdotally, I ran through the woods until I went to college and stress about the urban life I’m providing for my kids

It’s funny how as we increase a nations gdp, and general wealth, we commodify everything. day care, dog walkers, psychical activity, etc and then we have to go back and do all this market research and artificially recreate what was holistic about the more rural way of life.
There really is no free lunch!
