Final answer:
Anglo-American cultural subregions encompass the distinct cultural traditions from New England, the Mid-Atlantic, and the South, extending to include unique cultural practices in regions like the Mexican Borderlands and the Black Belt. Smaller ethnic islands also contribute to the cultural diversity of the United States. Likewise, Southern England, with London as its centerpiece, represents the affluence and diversity of Anglo-American culture.
Step-by-step explanation:
The subregions of Anglo-American cultural regions are reflective of the diverse cultural patterns and ethnic influences that migrated west from the original 13 colonies, which are New England, the Mid-Atlantic, and the South. Each of these cultural hearths contributes its unique traditions to the tapestry of American culture. In terms of dialects, for example, Yankee dialects are found in the northeastern states, attributed to the diffusion of culture from the region's hearth in Boston.
Furthermore, there are distinct cultural traditions seen in regions like the Mexican Borderlands and the Black Belt in the Lowland South, characterized by certain foodways, music, and celebrations. Additionally, several smaller ethnic regions or ethnic islands such as regions dominated by Italian-Americans, Irish-Americans, and Norwegian-Americans exist. These regions show the varied patchwork of cultures across the United States.
In a global context, places like Southern England also demonstrate the influence of Anglo-American culture, especially London being a primate city and a key player in the global economy, alongside representing a significant population hub that showcases cultural diversity due to immigration.
