Why Voting Matters
Why does voting matter in Humboldt County? Because every eligible voter here has exactly the same power at the ballot box: one vote. The next election for Humboldt 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 health care and retail means debates over health care costs directly affect Humboldt County families.
About 64,200 people voted for president in Humboldt County in 2024 (down about 7% from 68,800 in 2020). That equals roughly 59% of the county's estimated 108,000 adults, above the statewide rate of about 51%.
That means roughly 43,800 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, Humboldt County would add about 2,190 voices, more than enough to decide a close local race.
Humboldt County spans about 3,568 square miles of small towns and countryside, averaging roughly 37 people per square mile. The county is home to about 0.3% of California's population.
