Frederick's population has grown roughly 20% since 2010, driven by spillover from the D.C. metro corridor, and that demographic churn has steadily eroded the Republican margins that once made it reliably red in statewide contests.
Across the recorded series it reached a Democratic high of 74.9 points in 1912 and a Republican high of 40.7 points in 1972. Between 2020 and 2024 the county moved 0.9 points toward the Republican candidate; the 2024 margin was 8.7 points.
A population of 287,048, a 66% non-Hispanic-white share, and a median household income of $122,002 describe the county. The county's voting pattern over the last decade is most similar to that of Kent County and Gwinnett County.
