Originally the center of a major citrus-growing region, Orlando is now an urban city with various industries. The area is a major tourist destination and is the home of the Universal Orlando Resort, and SeaWorld. Orlando is also about 21 miles Northeast of Lake Buena Vista, Florida, home of the Walt Disney World Resort. These attractions helped make Orlando the third most visited American city among travelers in the year 2007. Since the establishment of destination tourism in the 1970s, the local economy has diversified, and today the region is the center of operations for companies servicing Central Florida. Orlando is also home to the University of Central Florida, the largest university campus by student enrollment in the state of Florida and among the largest in the United States.
In 2008, Orlando was listed as a "high sufficiency" world-city in the World Cities Study Group’s inventory by Loughborough University and is one category away from becoming a Gamma world city. According to Loughborough, Orlando now ranks alongside other cities such as Osaka, Glasgow, and Baltimore
