Little change over last 5 years
Roseville, Calif. – Placer County, long a bastion of conservatism in California continues to change. In the process, the region has evolved into a safer, more diverse, educated, and dramatically more prosperous county.
Waves of development, relative housing affordability, family friendly neighborhoods and great weather continue to attract highly educated residents and entrepreneurs from throughout California and the nation.
Greater prosperity & lower crime rates
These changes have brought greater diversity, economic prosperity, and lower crime rates according to local law enforcement records. These trends have bucked political and media propaganda which capitalizes on people’s fears. The growth has also delivered some of the big challenges communities face during periods of rapid growth such as a dramatic increase in traffic congestion and high density housing.
Republican advantage
According to Official Placer Elections data, Republican voter registration over the last two decades years has plummeted (data chart below). However, Republicans still retain a notable advantage in Placer County. For example, in both 2020 and 2024, Donald Trump outperformed in Placer County.
As of May 2025, there are a total of 295,400 registered voters in Placer County, an decrease of over 200 voters since last report.
Dissatisfaction with both major parties
The voter registration data also shows the biggest percentage change is that of voters not wishing to be associated with either major political party. Despite the long-term trend and downward trajectory of Republican registrations, Democratic registrations have only moved up slightly over the same period. No Party preference accounts for nearly 20 percent of registered voters with smaller political party registration rounding out the remaining eight plus percentage of registered voters.
Active Local Voters
Ryan Ronco, Placer County Clerk-Recorder-Registrar of Voters shared that Placer County is “historically 10 to 15 percentage points above the California average turnout each major election.” Placer County also currently ranks #2 for percentage of registered voters in California.
