Naperville is a city in the Chicago metropolitan area of Illinois in the United States. In 2006, Money magazine listed Naperville as #2 on its annual list of America's best small cities to live in. The city took the #3 position on the 2005 and 2008 lists.  As of the 2000 census, the city had a total population of 128,358, and the population was estimated at 147,779 in 2006. Naperville is the fifth largest city in the state, behind Chicago, neighboring Aurora, Rockford, and Joliet. Approximately 100,000 "Napervillians" live in DuPage County, while about 50,000 reside in Will County. Once a quaint farming town, Naperville has evolved into a wealthy city due in part to a massive migration of professionals in the 1990s seeking jobs and globally renowned public schools. This can be seen in part by the enormous growth of high-tech companies such as Tellabs, Alcatel-Lucent and the BP North American Chemical Headquarters, all located in Naperville. U.S. News and World Report recently ranked both Naperville School District 203 high schools among the top 3 percent of high schools in the country. Also, District 204's Neuqua Valley High School and Waubonsie Valley High School, located in Aurora, IL, won the Grammy Gold Signature School award in 2005 and 2007 respectively, ranking them top in the nation for a music program in a high school.
