Orange County is a county located in the U.S. state of North Carolina. As of the 2010 census, the population was 133,801. Its county seat is Hillsborough. It is home to the University of North Carolina at Chapel Hill, an institution of the University of North Carolina System and the oldest state-supported university in the United States.
The US Office of Management and Budget also includes Orange County as a part of the Raleigh-Durham-Chapel Hill Combined Statistical Area, which has a population of 1,998,808 as of U.S. Census 2012 Population Estimates. Effective June 6, 2003 the Office of Management and Budget redefined the Federal Statistical Areas and dismantled what had been for decades the Raleigh-Durham-Chapel Hill, MSA and split them into two separate MSAs even though the region still functions as a single metropolitan area.
