Montgomery County is Maryland’s most populous county. It’s not hard to see why as it’s right next door to Washington D.C. This makes it a prime spot for government workers. As for Maryland’s least populous county, that’s Kent County. It’s a rural area on the Eastern Shore, full of farmland and small towns.
Most Populous: Montgomery County
Least Populous: Kent County
Size wise, Frederick County is the biggest for landmass… so that means excluding water. It stretches from the Potomac River to the Pennsylvania border. Overall, it covers 660 square miles.
What’s the smallest county you ask? That’d be Howard County. Don’t let its size fool you, though. It’s home to Columbia, one of the first planned communities in the U.S. However, Baltimore City is only 92 square miles (80.9 square miles is its landmass).
Largest Area: Frederick County
Smallest Area: Howard County
Maryland’s counties have some interesting stories behind their names. Take Calvert County, for example. It’s named after the Calvert family, the founders of Maryland colony. The first counties in Maryland were set up way back in the 1630s, with St. Mary’s County being one of the oldest.
