California’s political geography reflects both growing national polarization and enduring regional differences. Using survey data and sophisticated modeling to estimate public opinion across 46 areas of the state, this report shows that while partisan alignment increasingly shapes views on major issues, Californians broadly agree on several policy topics. At the same time, a persistent coastal-inland divide—and the distinct political and economic position of the Bay Area—continues to structure differences in attitudes and lived experiences across the state.
- A strong coastal-inland divide defines California politics. Coastal regions are far more Democratic and liberal, while inland areas anchor Republican support. The modern center of California conservatism is the far north of the state. These broad partisan tendencies shape the geography of a wide range of issues, from immigration to the size of government to climate change and perspectives on the economy. →
- Independents are numerous but typically partisan in practice. Most lean toward a party and vote consistently that way. Democratic-leaning independents are concentrated along the coast, while Republican-leaning independents are more evenly distributed. →
- Most Californians agree on several key issues. Though the exact level of support varies, majorities across the state support abortion access, view immigrants as a benefit, and favor state action on climate change. Opposition is mostly limited to very conservative areas in the far north of the state. A broad geographic range of Californians also want a smaller state government, despite the state’s overall liberalism. →
- The affordability crisis is spreading inland. Residents on the coast are the most likely to say housing is a big problem in their part of the state, but concern about housing has grown the most in the interior over the last few years. Likewise, Bay Area residents have the most negative economic outlook, though those in inland California worry the most about paying their bills, including housing costs. →
- The Bay Area is distinct politically and economically. It is the most liberal and Democratic region, showing the strongest consistent support for progressive policies. Despite high housing prices in the region, Bay Area residents are also less likely to share the affordability concerns of the rest of the state.
