Source and method
Population: U.S. Census Bureau, American Community Survey 2020–24 5-year estimates; figures for 2020–24. Cities and towns in the Baltimore area with at least 5,000 residents and a published figure are ranked (48); Baltimore itself is left out. The metro area is the Baltimore-Columbia-Towson, MD metropolitan statistical area. Place names for ZIP codes are the neighborhood or city the ZIP code mostly covers. Compiled by Home Economics.
Zillow's "typical" home value and rent are index values for the middle of the market (the Zillow Home Value Index and Observed Rent Index), not median sale prices or asking rents. One-year changes are over the 12 months to September 2026. Income and population come from the Census Bureau's American Community Survey and carry sampling error, most of all in small places.
