Las Vegas and Phoenix are the top markets for both inbound andoutbound relocations for Southern California, according to newresearch from Zumper. The company's migrationreport shows that both Las Vegas and Phoenix were the top citiesfor relocation searches to and from Southern California.

For inbound relocation, housing affordability played a majorrole in residents' decision to move to Phoenix and Las Vegas. "Abig factor for this migration is that Phoenix and Las Vegas havemuch cheaper costs of living when compared to Southern Californiacities," Crystal Chen, marketing manager atNextdoor, tells GlobeSt.com. "One-bedroom rents inPhoenix and Las Vegas are both just under $1,000, while one-bedroomrents in Southern California cities range between $1,500 and$2,200. Renters in Southern California who are looking for moreaffordability but still want the fun city amenities are turning toPhoenix and Las Vegas."

Coastal Southern California's affordability crisis isn't news.The market's high housing costs have fueled outward migration tothe benefit of neighboring regions, including Phoenix and LasVegas, but also areas like the Inland Empire. However, theopposite—inward migration patterns from Las Vegas and Phoenix—wasunexpected to see in the research. "California is an incrediblysought after destination for many and for Las Vegas and Phoenixrenters specifically, a big draw may be that the weather issimilar, since all of these three regions are normally warm most ofthe year," says Chen. "Southern California is also a moreaffordable and spaced-out area when compared to expensive NorthernCalifornia, so for people who want to make a move to California,Southern California is a good entry point."
