Morphology
southwestern + united + state
The phrase is directly compositional: 'southwestern' denotes a directional/regional part and combines with 'United States' (the country) to yield the southwestern region of the U.S., so a B1 learner who knows the constituents can infer this meaning. This is a standard geographic naming pattern found across languages, making the MWE immediately understandable rather than idiomatic.
Etymology
Southwestern United States comes from a simple map idea: it names the part of the United States that lies to the south and west. That's why the phrase means this area, often the states of New Mexico, Arizona and Texas.
