Until the 1960s, Bridgewater was largely known as a farming community. In the 1970s its population began to grow when residents of larger cities such as Plainfield and Newark started to migrate into Bridgewater as a result of the 1967 Plainfield Riots and 1967 Newark riots. Subsequently, Bridgewater started to receive an influx of residents who worked in the strong pharmaceutical, telecommunications, and financial industries in Bridgewater and the Raritan Valley. More recently, there has also been growth as Bridgewater has become more popular with New York City commuters who use the Bridgewater Station on New Jersey Transit's Raritan Valley Line or Interstate 78 East to commute to New York City. Bridgewater is now a fairly developed suburban community, with only a few traces of its rural past still evident in the town (particularly in its northwestern section). Bridgewater is now Somerset County's second-most populous municipality, after Franklin Township.
