Philadelphia has been ranked as America’s fifth-most walkable city by Walk Score, a website owned by Redfin, which gave the city a ranking of 79.0, falling just behind Miami's score of 79.2. The top three cities were New York, San Francisco and Boston.

For many city dwellers across the country, owning and using a car as their primary mode of transportation is impractical. Only 64 percent of millennials living in Center City have access to a car, according to PlanPhilly.com. As SEPTA increases its fares, many Philadelphians find themselves relying on their own two feet to get them around town.

To calculate a city's Walk Score  hundreds of walking routes from individual addresses to nearby amenities are analyzed. Any amenity that can be reached via a five-minute walk or less is given maximum points. Pedestrian friendliness is also considered, with researchers analyzing population density and other metrics such as block length and intersection density.

Philadelphia also came in fifth in Transit Score, which analyzes how well the city is served by public transportation, and ranked number 10 in Bike Score, which measures how good a given area is for getting around by bicycle.
