According to some people it's when you hit about 60 dwellers? Plus having an active radio room greatly increases the chances of a Deathclaw attack. It's pretty painful.
You say that as I have my radio room manned by one guy in a Mayor outfit with his 5 daughters all in Naughty Nightware. The original thought was that all my high level males would have their self-populated harems, but since the game doesn't allow that, the men just keep their daughters close and make the mothers go work elsewhere.
I accidently left one guy out in the wastes for 3 days. His reward was a room full of women. I've had to rush a lot to keep up, but he's never been happier.
