About ZIP code 21780

The housing stock consists of predominantly single-family detached homes. Most homes were built in the pre-1940, giving the area an established character. Median home value is $395,000. Owner-occupancy is high at 80%, well above the national average.

The gap between median ($62,043) and mean household income suggests income inequality — a small number of higher earners pull the average up.

The dominant occupation class is management, business, and professional, with education and healthcare as the leading industry. An above-average commute of 44 minutes suggests many residents work outside the immediate area.

College attainment at 18% is below the national average, consistent with a trades and production-oriented local economy.
