Consistently chosen by Money as one of the greatest places to live in the United States, Naperville, Illinois, also has the distinction of being the wealthiest city in the Midwest with a population over 100,000. Situated in the middle of the highly influential Illinois Technology and Research Corridor, which hosts numerous private sector and government laboratories, including the Fermilab and Argonne National Laboratory particle accelerator complexes, Naperville has benefited from a steadily prosperous economy since its development began in earnest after the 1960s. As its borders extend over both DuPage and Will Counties, its 141,853 citizens also benefit from substantially lower taxes than are the norm for nearby Cook County. Named a 'White House Millennium Community' in 1999, Naperville is also noted for its excellent schools, safe atmosphere, and contemporary landmarks like the Moser Tower and Millennium Carillon. A distinctive precast concrete tower that is set to strikingly modern lines, the Carillon incorporates 72 separate bells that can be played by computer or human control. Though decidedly Midwestern in terms of its friendly and earnest culture, Naperville is therefore a city that has heavily invested in a future that is built around securing a high standard of living for all families.
