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.
