There have been quite a few posts on stats, and I noticed that there were a few bits of data that caught my eye. I didn't have enough information though to see if I was actually getting a trend, or just confirmation bias. So I wanted to look into it a little more.
I created this Google Doc Spreadsheet. Please take a moment to fill out the relevant data. If you have any suggestions for other data, please let me know. I did make the choice between Rural and Urban binary. It may require a bit of a judgment call on your part if you don't know how to qualify yourself, but that is hard logic on that question. Everything else is pretty free form.
Let's see if there are some specific things that jump out, and perhaps we can send this to Niantic so we have hard data to back up concerns.
EDIT TO ADD: Please let me know if I didn't share my Google Doc correctly, I don't often work in that format.
