North Carolina was hard hit by the Great Depression, but the New Deal programs of Franklin D. Roosevelt for cotton and tobacco significantly helped the farmers. After World War II, the state's economy grew rapidly, highlighted by the growth of such cities as Charlotte, Raleigh, and Durham in the Piedmont. Raleigh, Durham, and Chapel Hill form the Research Triangle, a major area of universities and advanced scientific and technical research. In the 1990s, Charlotte became a major regional and national banking center. Tourism has also been a boon for the North Carolina economy as people flock to the Outer Banks coastal area and the Appalachian Mountains anchored by Asheville.
