Why did the population in the US West increase between 1980 and 1990?

The population in the US West increased between 1980 and 1990 due to a combination of economic opportunities, migration, and a favorable climate. The region experienced significant economic growth, particularly in technology and services, attracting people seeking jobs and a better quality of life. Additionally, the appeal of the West's natural landscapes and lifestyle contributed to an influx of residents from other parts of the country. This demographic shift was further fueled by Immigration and a trend of people moving for retirement and recreational opportunities.
