Answer:
This is the only region where non-white ethnic groups form a majority in the population and the cowboy culture of this region developed around the rural occupation of cattle ranching.
Step-by-step explanation:
The Southwest is a region of the United States that borders Mexico on its southern side. This region is well known for having a big influence from Spanish speaking people groups. This is due to the history of the region, as it has initially been part of the Spanish empire and settled with Spanish speaking people, but later has been conquered by the United States.
It is not just the Spanish speaking people that were living in the area when the United States took over that form the majority of the ethnic composition nowadays though. Because of the development that the United States had had, and the problems in Latin America, over time millions of people migrated to this region.
This region was chosen by the people of Latin America because they knew that there are a lot of compatriots of theirs there, and the majority of the people understood Spanish, so it was going to be much easier to settle in. This process has resulted that nowadays this is the only region of the United States where the majority of the population is formed by non-white ethnic groups, often classified as Hispanic.
The region is also known for its cowboy culture. This is due to the large-scale cattle ranching on the vast grasslands of the Southwest. While this has its historical dimension, it still persists in modern times and just solidifies this type of reputation of this region.
