Question about villager cycles...

[D i a]

I believe I heard there was a 16 villager cycle in play before you could get a villager you had before, again.
I want to confirm this, but I'm also wondering if the 16 villagers have to have all been villagers moving away, or moving in, or a combination of both? I guess I'm a little confused as to how it works. I know that past animals show up in your Main Street, and I was wondering if that was random, or if that was signifying something, like being half-way through the villager cycle before you could get them again?

Any info would be greatly appreciated.

It's only the villagers that move out. You need to move 16 villagers out in order for the game to forget about that certain villager and for that villager to not appear in Main Street again. Hope this helped.
