What Is the Research Triangle?
The Research Triangle, often simply called "the Triangle," is a 13-county region in North Carolina anchored by three world‑class research universities: North Carolina State University in Raleigh, Duke University in Durham, and the University of North Carolina at Chapel Hill. Together they form a dense hub of research, technology, and business that drives one of the fastest‑growing economies in the United States.

Historical Roots and Naming
The term dates back to the 1950s when state leaders envisioned a "research corridor" linking the three campuses. In 1959 the Research Triangle Park (RTP) was created, becoming the nation's largest research park and cementing the region's identity as a collaborative innovation ecosystem.
Geography and Core Counties
The Triangle spans roughly 4,500 square miles and includes the core counties of Wake (Raleigh), Durham, and Orange (Chapel Hill), plus surrounding counties such as Chatham, Johnston, and Franklin. The area's central location on the East Coast provides easy access to major cities like Washington, D.C., New York, and Atlanta.
Key Institutions and Their Roles
Universities
- North Carolina State University – engineering, agriculture, and computer science.
- Duke University – medical research, biotech, and policy studies.
- University of North Carolina at Chapel Hill – life sciences, public health, and humanities.
Research Triangle Park (RTP)
Founded in 1959, RTP now hosts over 300 companies, ranging from startups to Fortune 500 firms, covering sectors like pharmaceuticals, information technology, and renewable energy.
Economic Impact
According to the RTP Foundation, the park contributes roughly $70 billion in annual economic activity and supports over 100,000 jobs. The broader Triangle region enjoys a median household income about 30% higher than the national average and a low unemployment rate, consistently below 4%.
