> You think Essex, Passaic and Bergen county cant lose 11k people/families from moving and not simply have that replenished AND EXCEEDED by their birth rate?

I think you have a couple of dense, impoverished towns in essex and passaic, where you may have seen some migration due to increased wages. In Bergen you really only have hackensack & englewood. Englewood i could see, hackensack is on an upswing. Maybe decreased migration to Ft.Lee\palisades park or first generation moving on from there? hard to say.

Bergen maybe you have older folks moving out, but pretty much anything in any of the bergen towns is quickly gobbled up. My house has still gone up in value post-pandemic and interest rate hikes when i look at recent comps.
