The Miami accent was developed by second- or third-generation Miamians, particularly young adults whose first language was English but were bilingual. Since
World War II, Miami's population has grown rapidly every decade partly because of the postwar
baby boom. In 1950, the
US Census stated that
Dade County's population was 495,084. Beginning with rapid international immigration from
South America and the
Caribbean (exacerbated by the
Cuban exodus in the early 1960s), Miami's population has drastically grown every decade since. Many of the immigrants began to inhabit the urban industrial area around
Downtown Miami. By 1970, the census stated that Dade County's population was 1,267,792. By 2000, the population reached 2,253,362. Growing up in Miami's urban center, second-, third-, and fourth-generation, Miamians of the immigration wave of the 1960s and 1970s developed the Miami accent. It is now the customary dialect of many citizens in the Miami metropolitan area. In 2023
Florida International University linguistics professor Philip M. Carter and
University at Buffalo doctoral student Kristen D’Alessandro Merii argued that the accent qualifies as a distinct regional dialect of American English. ==Phonology==
