146M is insane. The work force is 161M. I wonder how many profiles are people that are now retired or people that got discouraged and left the work force. A lot of college students probably have one too, and they aren’t in the work force yet.
A lot of people don’t know how to use LinkedIn and create new profiles when they change jobs / forget their old email/password combo - so there are several people on LinkedIn with multiple profiles that aren’t active anymore…
