You can get very close, I had an ad on Facebook the other day with transliterations of hindi/urdu words on it. When I clicked to see why, Facebook thought I was interested in a Pakistani newspaper (I think I'd read some articles on it on my phone, I guess the trackers picked that up). I guarantee you 99% of readers of the newspaper where I am (or probably anywhere) are of Pakistani descent. The ad wasn't telling me my race/national origin, but it was clear Facebook knew.
