Why Voting Matters
Voting is how Orange County residents shape the decisions made in their name. The next election for Orange County voters is California's presidential primary on March 7, 2028; local elections can come sooner, so check your local election office. Local work in restaurants and hospitality and health care means debates over tourism and small businesses directly affect Orange County families.
In the 2024 presidential election, about 1,391,000 ballots were cast in Orange County, down about 9% from 1,522,000 in 2020. With roughly 2,522,000 adults living in the county, that is around 55% of adult residents, above the statewide rate of about 51%.
That means roughly 1,131,000 adult residents did not cast a presidential ballot. Some are not eligible, but many are, and that is a lot of untapped power. If just one in 20 of them voted, Orange County would add about 56,600 voices, more than enough to decide a close local race.
Spread over about 791 square miles, Orange County averages roughly 4,009 residents per square mile, one of the denser places in California. The county is home to about 8.0% of California's population.
