Though some local businesses were using the term as early as 1966, it spread fairly slowly. The "Miami Herald"'s 1972 "Florida Almanac" refers to the area from Miami to Vero Beach as the "Tropical Coast". A 1982 survey of Florida's vernacular regions by geographers Ary J. Lamme and Raymond K. Oldakowski did not include the "Treasure Coast". The survey showed that the entire area from Dade County (now Miami-Dade) north to Martin County was considered the "Gold Coast" at that time. However, a 2007 survey by the same authors found that by then the "Gold Coast" was restricted primarily to Miami-Dade and Broward counties, while the "Treasure Coast" region had emerged describing the area from Palm Beach County northward. Lamme and Oldakowski noted that by that time, "Gold Coast" had acquired some unflattering connotations. They suggest the communities to the north may have seen the need to distinguish themselves from the Gold Coast and Miami to promote their locale as a destination for American tourists and residents, contributing to the current popularity of the Treasure Coast as a vernacular region.
