In the United States, the Hillbilly Highway is the out-migration of Appalachians from the Appalachian Highlands region to industrial cities in northern, midwestern, and western states, primarily in the years following World War II in search of better-paying industrial jobs and higher standards of living. Many of these migrants were formerly employed in the coal mining industry, which started to decline in 1940s. The word hillbilly refers to a negative stereotype of people from Appalachia. The term hillbilly is considered to be a modern term because it showed up in the early 1900s. Though the word is Scottish in origin, but doesn't derive from dialect. In Scotland, the term "hill-folk" referred to people who preferred isolation from the greater society and the term "billy" referred to someone being a "companion" or "comrade". The Hillbilly Highway was a parallel to the better-known Great Migration of African-Americans from the south.
