The St. Louis metro area exhibits high U.S. citizenship rates across most zip codes, with the majority exceeding 95% of the adult population, but a distinct cluster of lower citizenship rates (approximately 80–88%) is concentrated in the western suburbs near St. Charles and the surrounding zip codes to its south and southwest. This pattern suggests a notable concentration of non-citizen immigrant populations in the mid-county western corridor, contrasting sharply with near-universal citizenship rates in the eastern and northern portions of the metro, including Florissant and the areas east of St. Louis proper. A few zip codes in the central St. Louis urban core also show moderately lower citizenship percentages, likely reflecting pockets of immigrant communities within the city.
