The UC Berkeley Possibility Lab released findings from an October 2025 survey (fielded as part of the Institute of Governmental Studies (IGS) Poll) that suggest California’s registered voters are divided over current federal immigration efforts and whether these policies will negatively affect the state’s economy and culture. Although demographic factors like age and education level do shape attitudes within each party, these within-party gaps are modest compared with the large and consistent divides between Democrats and Republicans.

Read the full survey brief here. 

The survey finds that:

 
  • 51% of California voters oppose the current law enforcement effort to reduce the number of undocumented immigrants entering the U.S. illegally
  • 61% oppose federal efforts to deport all undocumented immigrants living in the U.S. today. 
  • 63% believe the current federal efforts to deport undocumented immigrants living in California will somewhat worsen or worsen a great deal, California’s economy.
  • 51% believe that the current federal efforts will somewhat worsen or worsen a great deal, California’s culture. 
 

The survey also finds that nearly a quarter of respondents report that either they or someone close to them, such as a family member or close friend, has been directly affected by the current efforts to deport undocumented immigrants. Moreover, a substantial share of voters (roughly 4 in 10) report that current deportation efforts are discouraging people in their local communities from engaging in a wide range of everyday activities, such as going to work, attending religious services, and sending their children to school (see chart below).

 

Many Californians express concern about federal immigration enforcement and perceived local impacts of current deportation efforts. 

These statewide averages, however, mask substantial partisan divides (see Table below). Democrats overwhelmingly oppose current federal immigration enforcement efforts and anticipate negative effects on the state. In contrast, only small minorities of Republicans express concerns.
