MuniMapz — Where to open your next business

Local economy intelligence for every U.S. ZIP code

MuniMapz is an interactive map of the United States that surfaces business opportunities at the ZIP-code level. We combine U.S. Census Bureau demographic data (population, median household income, age distribution, education, commute patterns, housing tenure) with real-time business density from OpenStreetMap, then compute an Opportunity Score for every (ZIP, business category) pair — showing you exactly where the market gaps are.

Click any ZIP marker on the map to see its population, median income, top business categories, and the most-underserved business types. Cluster markers aggregate stats across entire metro areas — click the New York cluster to see all of NYC's demographics and opportunity rankings rolled up.

Ask the Advisor — premium AI business analysis

Subscribers to MuniMapz Pro ($8.99/month, includes 100 questions) can ask our AI advisor questions like "What if I opened a ramen shop in 11211?" or "Where in NYC is the best spot for a dental practice?" — and receive a 1-to-10 likelihood-of-success rating with data-backed reasoning, citing the actual demographics, competitor counts, and opportunity scores for that specific area. Additional question packs available: 10 questions for $0.99, 100 questions for $8.99.

Built on real public data

Demographic data comes from the U.S. Census Bureau's American Community Survey (ACS) 5-year estimates for all 33,000+ U.S. ZIP Code Tabulation Areas. Business data comes from OpenStreetMap, geocoded via PostGIS spatial queries. The Opportunity Score engine uses demand-side population and income signals weighted by category-specific demographic fit (e.g., pharmacies index on % age 65+, bars on % age 18-34) against supply-side business counts per capita.
