I think all of you should look at the real question - what does the poll mean by "What is considered North/Central/South Jersey?" I mean, I could look at a map and draw two horizontal lines, evenly spaced, across the state. But, most of the people replying here aren't answering the question in purely cartographic terms. They bring in their own biases or preferences when imagining what makes up these three distinct geographies.
I grew up in Marlboro, which - like the rest of Monmouth County - I consider solidly Central. But, that's due to sociological reasons. I did not feel as though I had as much in common with the (just out of) New Yorkers who inhabit the northeast corner of the state, as well as most of the rest of the metro area. Same goes for the South Jerseyans from the Cherry Hill area, and their close ties to Philly. If anything, I'd imagine having more in common with folks who live much further south (on the Shore) and further west/northwest because they, too, didn't see themselves as either New Yorkers or Philadelphians.
