Population density can have a meaningful impact on home prices in an area. There tends to be more demand for available real estate in more densely populated areas, and home prices are often higher as a result. In Philadelphia a typical home is worth $240,900, more than the national median home value of $194,500. Philadelphia has the 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 Philadelphia lasts 29.1 minutes, longer than the average commute time for Pennsylvania as a whole of 26.8 minutes and the second highest of any metro area in the state.
One of the most effective deterrents to crime is other people. In denser cities there is often more people and more streetlight to act as natural surveillance that can in some cases prevent petty crime. Still, in the Philadelphia-Camden-Wilmington metro area, there were 2,196 property crimes per 100,000 people in 2015, lower than the national property crime rate of 2,487 incidents per 100,000 Americans and higher than the statewide rate of 1,813 property crimes reported per 100,000 residents. Philadelphia has the second highest property crime rate and highest violent crime rate in Pennsylvania.
