About Miami-Dade County
Miami-Dade County is not identical to the City of Miami. Its county-level demographic estimates include many municipalities and unincorporated areas.
The official county FIPS identifier is 12086. Its first two digits identify Florida, while the final three digits identify Miami-Dade County within that state.
How to interpret the map and statistics
The boundary layer is from the Census Bureau’s current TIGERweb service. The figures are derived separately from the 2020–2024 American Community Survey 5-year release. Because those sources have different vintages, small changes in boundary definitions or estimated totals may occur over time.
Use the map and data to explore broad geographic patterns, not to decide legal property lines, official tax jurisdictions, eligibility to vote, or emergency service coverage. Local government and parcel records are the appropriate sources for such decisions.
