Why Voting Matters
Voting is how Baltimore County residents shape the decisions made in their name. The next election for Baltimore County voters is Maryland's presidential primary on April 25, 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 Baltimore County families.
In the 2024 presidential election, about 410,000 ballots were cast in Baltimore County, about the same as the 415,000 cast in 2020. With roughly 677,000 adults living in the county, that is around 61% of adult residents, close to the statewide rate of about 61%.
That means roughly 267,000 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, Baltimore County would add about 13,400 voices, more than enough to decide a close local race.
Spread over about 598 square miles, Baltimore County averages roughly 1,425 residents per square mile, one of the denser places in Maryland. About 14% of all Maryland residents live here.
