Saint Peters vs O'Fallon

Side-by-side comparison of Saint Peters, MO and O'Fallon, MO - population, economics, education, health, hospitals, climate, and cost of living from official U.S. government data.

Reading a Saint Peters vs O'Fallon comparison, what matters, what doesn't

Saint Peters (53K residents in Missouri) and O'Fallon (85K residents in Missouri) differ first on the three numbers nearly every comparison starts with: median household income ($91,637 vs $110,443), median home value ($269,900 vs $326,200), and median rent ($1,321 vs $1,443 per month). Those three are highly correlated within a region but often decouple across regions because they respond to different levers, income tracks the local job market, home values track housing supply plus interest-rate pressure, and rent tracks short-run vacancy. Comparing all three at once is how you spot whether a city is "expensive because people earn a lot" or "expensive despite what they earn."

The second layer is the layer most headline comparisons skip. Poverty rate (5.6% vs 5.4%) and unemployment (2.3% vs 2.7%) describe the distribution under the median, which two cities with similar averages can present very differently. The share with a bachelor's degree or higher (39.2% vs 43.3%) is the single best proxy for income trajectory over the next decade. On healthcare, CMS Hospital Compare credits Saint Peters with 1 hospital (avg rating 3/5) vs O'Fallon's 1 (avg 4/5).

Areazine renders each row with a national-average tick mark precisely so you can tell in one glance whether both cities are above/below the U.S. norm (they often are, cities with active residential markets self-select for certain profiles) rather than focusing on which is "better." For life decisions, where to relocate, where to retire, where to enroll a child in school, pair this page with the individual city profiles below, where health indicators, hospital ratings, school counts, and climate normals appear in full rather than as the compressed single row you see here.
