Miami-Dade County, Florida

Miami-Dade County (most locals still call the county "Dade" since it was renamed from that in 1997) is part of the South Florida Metropolitan Area (aka the Tri-County Area). The county is home to 35 incorporated cities and many unincorporated areas. The eastern portion of the county is heavily urbanized with many high rises up the coastline, as well as the location of the county's central business and government district, Downtown Miami.

The western portion of the county consists of the Everglades National Park and is unpopulated. East of the mainland in Biscayne Bay is also Biscayne National Park, making Miami the only metropolitan area in the United States that borders two national parks. The county was originally named after Major Francis Dade. The county's total area is 1945 square miles, making it the third largest county in Florida.
