The contact map seems to be based on area code: https://github.com/michael-danello/iMessageWrapped/blob/cef20564e5744fb9a69ec0483ff1e124490b134e/imessage2020wrapped/app.py#L275-L290 https://github.com/michael-danello/iMessageWrapped/blob/cef2... Unfortunately area code of a cell phone number isn't a great indicator of where the owner lives (though to be fair you can't really tell otherwise). Relevant XKCD entry: https://xkcd.com/1129/ https://xkcd.com/1129/ In my case my area code (650) is where I went to college, and many if not most of my friends and colleagues seem to be in a similar position.
