Moving into the STATE of Florida ... absolutely a lot of Northerners. Into Miami? Vast majority over the past 20 years have been from Latin America. I lived in Coral Gables from 1989 through 2014 ... and had very few native English Speaking neighbors move in during that period. Had a lot of American neighbors move out ... and homes purchased by families that had move in from Guatemala, Colombia, Dominican Republic, Chile, Argentina, Brazil. Key Biscayne is most likely 95% Latino. The influx of wealthy and super wealthy Latin American business owners ... opening branch offices in Miami and establishing a 2nd or 3rd residence ... has been off the charts. I worked in Latin American Agriculture for over 40 years ... used to have to travel throughout Latin America for our sourcing operations and we owned / managed farms in Peru / Guatemala / Honduras / Dom Rep. Over the past 10-15 years a lot of growers we worked with opened offices in Miami or simply bought 2nd homes in Coral Gables, Doral, Key Biscayne, and we could do our business meetings here. Quite a change in demographics. Fantastic development of restaurants ... Peruvian Ceviche, Colombian cuisine, Dom Rep restaurants and Brazilian steakhouses. But horrible traffic.
