I wanted to start a discussion about this, because I think it's an important fact. If any of you guys are familiar with any of these cities, you'll notice a very big difference in the socioeconomic status of the areas where people are more actively exercising. What do you gather from this data? What do you think it means or implies?
Fact: Rich people are more likely to own a smartphone.
Fact: RunKeeper is an app for smartphones and requires GPS.
Fact: The article quoted uses RunKeeper for all its data and conclusions.
Fact: Their conclusion ... and yours ... is that poor people don't exercise because according to this RunKeeper data, they're only working out in nicer areas.
Do you see the disconnect?
Correlation does not equal causation. Just because there is no RunKeeper data in the poorer areas, does not mean that there is no one working out in those areas. It simply means that there are less people using smartphones, and in effect using apps like RunKeeper.
