"No big city grows _ and shrinks _ at a higher rate each workday than the nation's capital, which sees its daytime population swell by 72 percent as commuters stream in...New York City grows by the most people during the day, about 563,000. But that's only 7 percent of the city's population of 8 million...Atlanta grows by 62 percent while tiny Lake Buena Vista, Fla., near Walt Disney World, grows by a whopping 192,238 percent. That city, about 20 miles southeast of Orlando, has just 16 residents, according to the 2000 census. But it grows to 30,768 during the day from workers commuting to Disney and surrounding businesses."
