Let's see how many people move within California versus those who moved from The Golden State to another state.
Out of all California household moves, approximately 46% of them have been local ones, with 54% of the people moving to another state in the country.
Despite being the home of the nation’s second- and third-largest urban economies (the Greater Los Angeles Area and the San Francisco Bay Area respectively), the majority of Californians have still chosen to move out of the state.
