Experts have ruled that San Diego's population growth fueled by immigration is not good for the city. The majority of last year's growth is attributed to the county's net gain of 24,226 immigrants, both legal and illegal. Some experts believe that relying on immigration for population growth is risky and could hurt the workforce. Others see the population surge as a sign of U.S. citizens leaving due to the area's housing crisis. Only one expert stated that population growth driven by immigration is a good thing. This comes as San Diego experiences a significant drop in border crossings after Trump ended the CBP One appointment system.
