Why Voting Matters
Voting is how Hillsborough County residents shape the decisions made in their name. The next election for Hillsborough County voters is Florida's presidential preference primary on March 21, 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 Hillsborough County families.
About 672,000 people voted for president in Hillsborough County in 2024 (down about 6% from 712,000 in 2020). That equals roughly 54% of the county's estimated 1,251,000 adults, below the statewide rate of about 57%.
That means roughly 579,000 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, Hillsborough County would add about 28,900 voices, more than enough to decide a close local race.
Spread over about 1,020 square miles, Hillsborough County averages roughly 1,550 residents per square mile, one of the denser places in Florida. The county is home to about 6.8% of Florida's population.
