How many people do you know? You’ve probably never counted. Well, now you don’t have to. Tyler McCormick has worked it out: around 600.

Or more precisely 611, according to estimates by McCormick, a professor in the statistics and sociology departments at the University of Washington. That’s a national average, but McCormick can actually compute an estimate for you, or anyone.

Asked how many close friends they have, about half of Americans say three or fewer, according to a 2021 survey. The British anthropologist Robin Dunbar, drawing on studies of the brain sizes of humans and other primates, estimates a person can only maintain about 150 relationships. The so-called “Dunbar number,” he has said, “applies to quality relationships, not to acquaintances.” A Pew Research study found adults on Facebook had an average of 338 friends on the site.

The number of people you know, without considering them friends, is probably much larger. McCormick’s definition: “that you know them and they know you by sight or by name, that you could contact them, that they live within the United States, and that there has been some contact” in the past two years.

Possible Preaching Angles:

(1) As a negative illustration, this could show our need to develop deeper, more intimate friendships in the body of Christ. (2) As a positive illustration, this could reveal that our support system may be stronger and broader than we realize, especially in the church.
