How a central New Jersey county became a global cultural and economic powerhouse

In short: Middlesex County is more than a New York City commuter hub. It is the state's third-most populous region, a center for scientific innovation, and home to the largest and most diverse Desi cultural enclave in the United States. Discover why this historic territory remains a vital engine for New Jersey.

Established in 1683, Middlesex County has evolved from a colonial administrative district into a cornerstone of the Northeast megalopolis. Named after its English namesake, the region is defined by the Raritan River, which historically facilitated early settlement and industry, including extensive clay mining that persisted into the late twentieth century. Today, the county serves as a critical transportation nexus, where the state's two most heavily trafficked motor vehicle arteries—the New Jersey Turnpike and the Garden State Parkway—converge in Woodbridge Township.

The county is a demographic standout, holding the highest concentration of Asian Indians in the United States. This influence is anchored by the Oak Tree Road commercial corridor, which spans Edison and Iselin, and is supported by a growing presence of other communities, including a significant Sikh population in Carteret. This diversity is reflected in civic life, where election ballots are printed in five languages: English, Spanish, Gujarati, Hindi, and Punjabi. The region also maintains a robust Jewish community, recently hosting a massive gathering in Edison.

Economically, Middlesex is a powerhouse, generating a gross domestic product of $59 billion in 2021. It hosts major headquarters and facilities for global entities such as Johnson & Johnson, Novo Nordisk, and Bristol-Myers Squibb, alongside the flagship campus of Rutgers University in New Brunswick. Despite its dense development and urban character, the county preserves over 6,300 acres of public parkland. Governed by a seven-member Board of Commissioners, the county has remained a political stronghold where no Republican has won a countywide election since 1991.
