About half of the metropolitan area’s 2.5 million residents were born outside the United States in Latin America, the Caribbean, Europe and Asia, and two-thirds speak a language other than English at home. More than 1.6 million residents are Hispanics (of any racial background), 425,000 are black (non-Hispanic) and 350,000 are white (non-Hispanic), while 100,000 are classified as "other."

Miami-Dade's population has a younger average age than most other Florida communities – another advantage for companies seeking to compete in the global marketplace. 

Miami, Hialeah and Miami Gardens are the three largest municipalities in Miami-Dade County. About 1 million residents live in unincorporated areas, with services provided directly by county government.
