Earlier quoted context omitted.
They probably know your neighbors because you both have the same SSIDs in your vicinity.. I don't see FB not knowing this. Or if you allowed GPS, and neighbors did too, then it's even easier to make the connection.
My co-workers from the office are frequently recommended to me on FB. Since I don't have their number, it must be location based.

#22I haven't used my Facebook account in years, ever since they recommended I connected with a person I'd known for 20+ years but with whom I shared no connections or commonalities apart from our nationality. As I remember it, neither of us had listed schools, jobs or interests in our profiles. Maybe it was a coincidence but it made me very anxious so I left the platform.
What were you anxious about happening as a result?

#23And this is why under German law the BDSG §34 exists, which allows every citizen to request, once every 12 months, for free, from every company a list of all data the company has on the citizen, how they got it, whom they gave it to, and all statistical models that were derived from the data, or that had an influence on the data. It’d be interesting to make a BDSG §34 request about "People you may know", just to see…
How does Facebook report inferred connections or connections deduced by looking at a larger graph? Their obligation to tell you what they know about you shouldn't infringe on my privacy.

It's possible that one of you connected Facebook to a service along the way that provided access to contact information like email or phone number and they used that to make the connection.

Of course, in the background they likely knew you were more connected through mutual friends, contacts, etc

#27I've just assumed this is through whatsapp. I've logged into whatsapp with my phone number, fb know my phone number (2fa codes), and they've slurped my address book from my phone and then show me connections on fb that are a few degrees of separation. This is the only way I can think that neighbours I barely know show up on the "people you may know" feature -- we're connected through neighbours I know far better.
You are 100% correct about this. People have appeared on "People you may know" when I have absolutely zero connection to them other than I have chatted to the on What's App... I'm afraid I may have to stop using the service soon... was great until FB bought it.

#28TL;DR: I think their graph includes non-FB-using people.
