There are 5,436 people per square mile in the Baltimore-Columbia-Towson metro area, lower than the national population density of 6,321 Americans per square mile across all U.S. metro areas. Baltimore also has the highest population density of any Maryland metro area.

Population density can have a meaningful impact on home prices in an area. There tends to be less demand for available real estate in sparsely populated areas, and home prices are often lower as a result. In Baltimore, a typical home is worth $290,300, more than the national median home value of $194,500. Baltimore has the second highest median home value of any metro area in the state.

Dense metropolitan areas are often the most congested, with the average worker spending up to 38 minutes commuting to work in some cities. The average commute in Baltimore lasts 30.3 minutes, shorter than the average commute time for Maryland as a whole of 32.6 minutes and the second highest of any metro area in the state.

One of the most effective deterrents to crime is other people. In more rural cities there is often fewer people and less streetlight to act as natural surveillance that can in some cases prevent petty crime. In the Baltimore metro area, there were 2,625 property crimes per 100,000 people in 2015, higher than the national property crime rate of 2,487 incidents per 100,000 Americans and higher than the statewide rate of 2,315 property crimes reported per 100,000 residents. Baltimore has the third lowest property crime rate and highest violent crime rate in Maryland.
