About
Life in Williamstown
Living in Williamstown means settling into a stable, family-oriented community in South Jersey that's grown steadily but hasn't lost its suburban character. The median household income sits around $89,000, and homes run roughly $279,000 with rents averaging $1,262 a month—reasonable for the region, though you'll want to factor in that 35-minute average commute if you're working elsewhere in the area. Summers here are warm and humid (averaging 76.7°F in July), winters are mild but chilly (around 33°F in January), and you'll need to be ready for the humidity that comes with the subtropical climate—it's not Arizona living.
