For much of its history, Somerset County was primarily an agricultural county. In the late 19th century, the Somerset Hills area of Somerset County became a popular country home for wealthy industrialists. The area is still the home of wealthy pharmaceutical industrialists.
In the 1960s, townships that were once exclusively agricultural were quickly transformed into suburban communities. Examples include Bridgewater Township and the Watchung Hills communities of Watchung, Green Brook and Warren Township. This growth was aided by the development of the county's very strong pharmaceutical and technology presence. Indeed, Warren Township used to be considered "the greenest place in New Jersey." More recently, there has been an influx of New York City commuters who use New Jersey Transit's Raritan Valley Line and Gladstone Branch or use Interstate 78.
