The most interesting thing I stumbled across so far is Detroit, where people don't run in huge swaths of the neighborhoods. I'm familiar with the city so I expected dead zones, but nothing like this.

> where people don't run

More accurately it's where people don't send their tracking data. Plausible to also say that it's where people don't own this tracking software/device at all. However it seems like a gigantic stretch to derive that there's no running going on.

That's true. Nevertheless, it's interesting (though unsurprising), to see the areas where Strava users don't run.

Maps ok-ish to the African American population distribution

In the US, it's almost entirely rich, white people that upload data to strava. You can easily see racial/economic divisions in any major united states city. Baltimore is a great example[1]; white people live in the center but not on the east or west sides (Canton excepted).

I'm not sure it is that simple. May be college/university education is a better predictor for Strava usage. But given that education in the US correlates with both race and income it is hard to say without controlling other variables.

It's even more apparent in Chicago.
