Somerset County, New Jersey: Pharma Money, Prestige Suburbs, and a Surprisingly Fragile Rental Market

There's a reason Somerset County consistently ranks among the wealthiest counties in the United States — and it's not just old money or Wall Street commuters. This is the heart of New Jersey's pharmaceutical corridor. Bridgewater, Basking Ridge, and Bedminster host or have hosted the headquarters of Johnson & Johnson, Sanofi, and Verizon, among others. That corporate infrastructure has created a highly educated, highly compensated workforce that has reshaped the county's housing market into something that looks less like a suburb and more like an asset class.

The median household income of nearly $136,000 — nearly double the national figure of $75,149 — is striking on its own. But the more revealing number is the per capita income of $70,321, which suggests the wealth here is distributed across adults, not just top-heavy. With more than a quarter of residents holding graduate degrees and over 31% holding bachelor's degrees, Somerset's labor pool is among the most credentialed in the Northeast.

A Housing Market Running Hot

The 11.6% year-over-year price increase is the headline that demands attention. At a median sale price of $600,000 — with the top decile of transactions clearing $1.27 million — Somerset is experiencing appreciation that outpaces even many coastal metro markets. What's driving it? Post-pandemic migration from Manhattan and Brooklyn continues to flow into Morris and Somerset counties, where buyers find larger homes (averaging over 2,000 square feet) with access to top-ranked school districts. With a vacancy rate of just 2.5% and only 1,596 sales recorded in the past 12 months against a total housing stock of over 132,000 units, this is a deeply constrained market.

The Renter Paradox

Here's the uncomfortable subplot: Somerset County is legitimately wealthy, yet its renters are under serious financial stress. The rent burden rate of 45.7% — meaning nearly half of renters spend more than 30% of income on housing — is alarming for a county with these income levels. Nearly a quarter (24.5%) face severe rent burden. With a median rent of $1,921 and a Gini index of 0.462 (well above the level economists consider a warning threshold for inequality), the county's prosperity is clearly not evenly distributed. The workers staffing restaurants, retail, and healthcare services that support this affluent community are quietly housing-stressed.

The 20.5% work-from-home rate — one of the highest in New Jersey — also reflects the bifurcated economy: knowledge workers Zooming from Bernardsville farmhouses, while essential workers commute in.

FAQs

What makes Somerset County unique in New Jersey's real estate market? Somerset sits at the intersection of pharmaceutical industry wealth and post-pandemic suburban demand, creating one of the tightest and most expensive housing markets in the state. Its combination of corporate headquarters, elite school districts, and scenic landscapes (including preserved farmland in Bedminster and Far Hills) gives it a profile unlike any other New Jersey county.

Is Somerset County a good place to buy a home right now? For buyers who can qualify, the fundamentals are strong — low vacancy, rising values, and a high-income employment base nearby. However, at a price-to-income ratio of roughly 4.4x even against the above-average local incomes, affordability is tightening. Entry-level buyers face a floor around $340,000, and competition at that price point is fierce.

Why are renters struggling in such a wealthy county? The county's rental stock is modest — only 25.5% of households rent — and hasn't kept pace with demand from workers who can't afford to buy. The result is a compressed rental market where even middle-income tenants are squeezed, a pattern common to high-cost suburban counties across the Northeast.
