Start with the correct St. Louis geography
The U.S. Census Bureau records St. Louis city as a municipality and identifies its county relationship as St. Louis city. Its 2020–2024 ACS 5-year population estimate is 288,512; a margin of error is unavailable. That number describes the municipality only. It does not establish search demand, legal need, competition, leads, cases, or revenue. For programmatic SEO, the more useful question is where the firm is genuinely prepared to serve clients. A St. Louis city page may be appropriate for a firm serving the city. It should not silently imply service throughout a different county or metropolitan area.
Recommended approach
Define the footprint in exact terms: St. Louis city, selected Missouri counties, or a statewide area. Keep service boundaries consistent with the firm’s intake policy and attorney licensing decisions. Do not use the population estimate as a reason to publish pages beyond the firm’s actual service area.
