O'Fallon has been one of the fastest-growing cities in Missouri since 2000, roughly doubling in population over that period. The city was named after John O'Fallon, a St. Louis businessman and Missouri Pacific Railroad executive in the 1800s. The railroad's routing through St. Charles County made O'Fallon a growth candidate long before the freeway-driven suburban expansion that followed after 1960.

Moving in O'Fallon: FAQ.
Is O'Fallon MO or O'Fallon IL?
Two different cities in different states — both in the St. Louis metro. O'Fallon MO (population 90,000) is in St. Charles County west of St. Louis. O'Fallon IL (population 32,000) is in St. Clair County east of St. Louis across the Mississippi. When hiring movers, always confirm the state in writing — they're 45 miles apart and served by different mover regulatory jurisdictions.
Is O'Fallon a good school-district choice?
Yes, generally. Fort Zumwalt School District is consistently top-rated in Missouri, and Francis Howell School District (which serves parts of O'Fallon and adjacent areas) is also strong. Specific school feeder boundaries significantly affect property values and desirability. Research feeder schools before buying.
How does O'Fallon compare to Chesterfield or St. Charles?
Chesterfield is the most affluent St. Louis western suburb with the highest median prices. St. Charles (the city) has charming historic downtown but older housing stock. O'Fallon offers newer construction, strong schools, and rapid growth at prices somewhat below Chesterfield. Many families see O'Fallon as the value-oriented upscale suburb of St. Louis' west side.
What's the commute to downtown St. Louis?
30-45 minutes via I-70 to I-64/I-70 depending on specific destination and time of day. Rush-hour traffic can extend the drive significantly. Many O'Fallon residents work in St. Charles County itself (Mastercard, Express Scripts, healthcare) or in Clayton/Creve Coeur corporate parks (20-30 minutes), avoiding the downtown commute.
