Miami-Dade County is located on the coast, at the South-East tip of Florida. Despite being home to a grand total of 34 incorporated cities including Miami, the largest city in the county, Miami-Dade is only the fourth most densely populated county in Florida.

More than half (52%) of the people who live in Miami-Dade were born outside of the USA.
Because of its high Hispanic and Latino population, almost two thirds of the population speaks Spanish as their mother tongue.

MIami-Dade County Population Growth
Miami-Dade was founded (as Dade County) in 1840 and, almost immediately its population of 446 began to shrink. Between 1840 and 1860 it fell to just 83 people. This drop in the Miami-Dade County population is probably due in part to the ongoing conflict between the US Army and the Seminoles, known as the Seminole Wars, which were fought between 1816 and 1858.
Since then, however, growth has been steady – as high as 475% per decade in the late 19th century. Today growth hovers between 10-20% per decade.
