The St. Louis metro has 2.8M residents (per 2024 ACS 5-year Estimates ), a 2024 median household income of $80K, median home value of $245K, median age of 40, and a 38% bachelor's-degree share among adults 25 and older. The analysis below clusters neighborhoods within the metro's urbanized areas, covering 1.9M of those 2.8M residents. The western St. Louis County suburbs around Ladue and Chesterfield lead on home values, incomes, and education, while the Illinois communities east of the river and North St. Louis sit at the bottom.
Median home value
The highest values sit in the western St. Louis County suburbs. The area north of Ladue — the wealthiest suburb in the metro — tops the metro at $855K, with the area west of Chesterfield at $687K, south of Ladue at $685K, north of Town and Country at $571K, and the area west of St. Louis at $559K. At the bottom, the lowest values are across the river in Illinois and in North St. Louis: the area west of East St. Louis at $46K, east of Cahokia Heights at $54K, south of Fairmont City at $58K, the area south of Granite City at $68K, and a north St. Louis cluster at $70K. The ≥$400K tier is confined to the western county suburbs; the under-$100K tier covers the Illinois Metro East and the north city.
Median household income
The area west of Chesterfield tops the metro at $214K, followed by the area north of Ladue at $204K, south of Ladue at $188K, north of Town and Country at $152K, and east of Chesterfield at $133K.

The ≥$120K tier follows the western county suburbs; the under-$40K tier sits on the Illinois side, where East St. Louis lost more than three-quarters of its peak population after its industries closed.

The area north of Ladue tops the metro at 49, with the area west of Chesterfield at 47, and the areas north of Town and Country and east of Wildwood at 46. The youngest neighborhoods are scattered on the Illinois side and the inner suburbs: the area east of Cahokia Heights at 30, east of Bridgeton at 32, and the areas south of Berkeley and around East St. Louis at 33. Most of the metro sits in the 38–44 range; the ≥44 tier traces the western county.
Adults with a bachelor's degree

Where the metrics overlap
The western St. Louis County suburbs sit at the top of home value, income, education, and age all at once — the area north of Ladue leads the metro on home value, education, and age together, while the area west of Chesterfield tops income. The Illinois Metro East forms the opposite corner: the area east of Cahokia Heights pairs a $54K home value with a $38K income, a 14% bachelor's share, and one of the youngest median ages at 30. North St. Louis and the inner north county around Jennings round out the bottom on value and education.
