In some cases, the data confirmed conventional wisdom. (Yes, the neighborhoods around Center City have grown in wealth, population and home values.) But it also offered up surprises. For one thing, it revealed the duress being experienced by middle-class neighborhoods in the Northeast and Northwest. It also revealed that some poor neighborhoods have made slow, but steady progress. Fairhill remains the city's poorest neighborhood, yet our data analysis shows that it beat the city average in progress on some key indicators, including crime reduction, and population, income, and home value growth. The progress catapulted the area into our "advancing" category. Another advancing neighborhood is Nicetown, a section of North Philadelphia that has struggled since highway planners ran an expressway over it in the 1950s. Later in this story, Majeedah Rashid, head of the Nicetown Community Development Corporation, explains the hard work needed to rebound.
