I don't know about other countries but in the US, there are things called Whitepages which list names, addresses and phone numbers of the majority of people/businesses.

Address data is pretty worthless considering how many places you can get such data.

It's 2016 -- forget the Whitepages. Most people publicly update all of this information everyday, multiple times per day, through their social media accounts.

They usually don't publish their street address on social media.

You're right, they usually post a GPS location that is even more specific.

Good point. I think most people don't do that, though, since it's typically "opt-in".

People do opt in. People outside of the tech game don't think of these as making themselves more vulnerable -- they only see convenience (or just blindly click yes to anything).

I had a Twitter app (Tweetcaster?) that had a "show local tweets" option, and was amazed by how I could determine the individual dorm rooms tweets were coming from on a nearby college campus.
