Louisianians descended from the French Acadians of Canada are also Creoles in a strict sense, and there are many historical examples of people of full European ancestry and with Acadian surnames, such as the influential Alexandre and Alfred Mouton, being explicitly described as "Creoles." Today, however, the descendants of the Acadians are more commonly referred to as, and identify as, 'Cajuns'—a derivation of the word Acadian, indicating French Canadian settlers as ancestors. The distinction between "Cajuns" and "Creoles" is stronger today than it was in the past because American racial ideologies have strongly influenced the meaning of the word "Creole" to the extent that there is no longer unanimous agreement among Louisianians on the word's precise definition. Today, many assume that any francophone person of European descent is Cajun and any francophone of African descent is Creole—a false assumption that would not have been recognized in the nineteenth century. Some assert that "Creole" refers to aristocratic urbanites whereas "Cajuns" are agrarian members of the francophone working class, but this is another relatively recent distinction. Creoles may be of any race and live in any area, rural or urban. The Creole culture of Southwest Louisiana is thus more similar to the culture dominant in Acadiana than it is to the Creole culture of New Orleans. Though the land areas overlap around New Orleans and down river, Cajun/Creole culture and language extend westward all along the southern coast of Louisiana, concentrating in areas southwest of New Orleans around Lafayette, and as far as Crowley, Abbeville, and into the rice belt of Louisiana nearer Lake Charles and the Texas border.
