O Fallon, MO — Lake Saint Louis, MO

This side-by-side compares ZIP 63368 (O Fallon, MO) and ZIP 63367 (Lake Saint Louis, MO) using the same Census ACS 5-Year table fields for both — no averages swapped in, no national proxies. ZIP 63368 has a population of 43,360 at 1,016 people per square mile, while ZIP 63367 has 19,433 at 561 per square mile. That difference in population size and density alone reshapes how every other metric should be interpreted — a higher-income ZIP with 1,200 residents behaves very differently from one with 45,000.

On income and education, ZIP 63368 reports a median household income of $124,297 against $137,648 in ZIP 63367, with per-capita income of $52,532 vs $59,320. The share of adults holding a bachelor's degree or higher is 50.9% in 63368 and 52.0% in 63367. Poverty rate reads 3.8% vs 3.2%, and unemployment 2.1% vs 3.8% — these four fields alone drive most of the difference in the scorecard grades you will see for each ZIP.

Housing separates these two ZIPs further: median home value sits at $349,200 in 63368 versus $409,100 in 63367, with median rent of $1,482 and $1,634 per month respectively. Homeownership rate is 82.0% vs 81.5%. When reading the comparison table below, focus on paired metrics rather than single winners — a ZIP with lower home values and lower income is not strictly "worse" if rent-to-income ratios and commute times land in the same zone. Every value is pulled from the exact same ACS table so the two columns are genuinely comparable.
