Might I ask what demographic group you are in? I personally am in the "founding generation of FB" (now a early 30s engineer in the US) and it's obvious to me that at least the people I know aren't giving data that much to FB. While plenty lurk or use messenger, quick sampling shows < 10% of my friends update more than once a month. So to answer your questions: > How does Google know my birthday > exactly how old I am I'll give you FB has exactness better specified, though I question how relevant it is. Regardless, gmail could easily figure this out by looking at inbound emails. Also linkedin public profiles. > the events I said I was interested in Given the lack of updates on FB, search is a much better proxy for this. > everytime I change jobs Email + linked in > my relationship status Search and email is going to be a very good proxy here, possibly better if FB updates are stale. > where my wife and I went to see a show the other night Maps. (And I'd guess usage of maps far outweighs people who voluntary tell FB) > Google doesn’t have the level of data for iOS devices on locations. iOS users in western countries are far more statistically valuable to advertisers than Android users. Yes, but number of Google-Android users, let alone users who use Google products, probably far outweighs frequent FB updaters.

Might I ask what demographic group you are in? I personally am in the "founding generation of FB" (now a early 30s engineer in the US) and it's obvious to me that at least the people I know aren't giving data that much to FB. While plenty lurk or use messenger, quick sampling shows < 10% of my friends update more than once a month. We aren’t talking anecdotally about “people you know”. Facebook has more than 2 billion daily active users. I'll give you FB has exactness better specified, though I question how relevant it is. Regardless, gmail could easily figure this out by looking at inbound emails. Also linkedin public profiles. Google claims it doesn’t use email for targeting ads and how will it correlate LinkedIn profiles with Google users? I doubt that MS owned LinkedIn is going to share the data. LinkedIn only has 260 million active monthly users. Given the lack of updates on FB, search is a much better proxy for this. Lack of updated by your circle...not based on published numbers. Search and email is going to be a very good proxy here, possibly better if FB updates are stale. How many people use email in 2018 for personal communications? Besides.... https://www.mnn.com/green-tech/computers/stories/how-facebook-knows-when-youll-get-divorced-even-before-you-do https://www.mnn.com/green-tech/computers/stories/how-faceboo... Maps. (And I'd guess usage of maps far outweighs people who voluntary tell FB) People only use maps when they don’t know where they are going. People will check in a lot more.
