Why are people fleeing California? Rising housing costs, taxes

California experienced a "net outward migration" of 61,100 people in the last twelve months, the biggest exodus since 2011.

"They're taking advantage of the housing bubble right now," McElfresh said. "The majority of the people we are seeing are moving to states that don't have state income taxes."
