Facebook Research estimated 3.5 degrees of separation for users on its platform back in 2016. I'd be very interested to see any follow-up studies. https://research.fb.com/blog/2016/02/three-and-a-half-degrees-of-separation/ https://research.fb.com/blog/2016/02/three-and-a-half-degree... Personally, I got a score of 2.91 degrees of separation at the time, and at that point I had 3715 friends. Now I'm at 4037. I only add people who I met in real life, even if I only met them once at the CouchSurfing meetup or a similar international group. I try to get back in touch with people when I travel, so I can be welcomed in every city around the world (and I try hard to welcome others when they come to wherever I'm based).
