how often do jobs cycle back to a city?

I’ve noticed that BI positions tend to post 5 to 7 new jobs on job websites literally everyday now. The city I’m trying to move to is New Orleans but right now only SCIS is hiring and they have had that job posted for almost a year now…
Perspecta was hiring for there but the position has been taken down just two weeks ago so I’m guessing they found someone.
So I’m wondering in your experience, how often do you see BI jobs cycle back to a city in term sof an opening? Particularly NOLA?
