I would have picked Chatham too as Crime index in Watchung is 8X of Chatham. Asian is only 4.8%(87% white) in Chatham vs 12.5%(76% white) Watchung. I have friends live in both places and they have bought Jersey City condos for easier commute to Hudson Yard(before the pandemic)Surprsingly, median housing price is more expensive (150K) in Watchung vs Chatham. Houshold income is also a toss up but as I said, I would have chosen Chatham any day over Watchung。
