Nearly 50 percent of Bay Area residents are planning to leave the region in the next few years. According to a recent survey by the San Francisco Bay Area Council, just under half of the nearly 500 survey takers cited rising housing costs, high cost of living and traffic as reasons to move out. By contrast, in 2016, under 35 percent of those surveyed said they planned to move out. Of the total respondents, just over 60 percent said they would leave California altogether, and roughly 25 percent would move within the state.
