The Midwest is a region that has been predominantly settled and influenced by Germanic people groups, mostly engaged in agriculture.
The Norhtwest is a region well know for its progressive views, and one of them, the environmentalism, is becoming an essential part of its culture.
The Southwest is a region where the Spanish-speaking population dominates, so it so no wonder that it is a hotspot destination for the immigrants from the Spanish-speaking countries of the Americas.
The West Coast, despite not being physically connected with the Hawaii Islands, still managed to have a big cultural influence on the people on these islands, so often these islands are included in the West Coast cultural region.
