My Math Forum Question for Odds

I'm sure I will mess this question up so I apologize. Question: What are the odds that 2 Strangers, living in a population of 250, would move every 2 years to same new Counties, for 8 years. The counties all have about 1,000,000 population. I'm sure this is going to need many variables to determine odds, but is there an equation before adding variables that I could use first?

Do the other 248 all know each other?!
Your problem makes no sense to me...

Are all people moving? Are all people strangers to each other? You need to clarify what you intended. Thanks from Denis

If you are trying to confirm a stalking incident consider it confirmed.

The probability that such a set of moves would happen by chance is infinitesimal.

"would move every 2 years to same new Counties, for 8 years":
