Final answer:
No states are simultaneously part of the West, the Upper Midwest, and the Deep South because these regions are geographically distinct and do not overlap.
Step-by-step explanation:
There are no states that specifically belong to both the West and the Upper Midwest and Deep South regions simultaneously, as the regional definitions are geographically distinct. According to the descriptions provided, areas such as the Northeastern Core include parts of the upper Midwest, while the Deep South implies a separate, southern location. The list provided includes states such as Illinois, Indiana, Ohio, and Michigan as part of the upper Midwest, and these do not overlap with the traditional Deep South states. States like Kentucky may have differing perceptions of belonging to the Midwest or the South, but they are not typically classified as Western states.
