Plainsboro, NJ, United States

At just over 24,000 residents, Plainsboro boasts a hefty price tag, with the median household income topping $120,000. While the township has seen rapid development, driven by Princeton University's expansion, the bureaucratic headaches are a persistent challenge. An outer-ring suburb of New York City, Plainsboro appeals to well-heeled professionals seeking a spacious, diverse community with excellent schools - though the 35-minute commute may prove a dealbreaker for some.
