While checking on the competition I stumbled upon this.

You will see this a lot where a plumber will advertise phone numbers to give the impression that they have multiple locations across the city (I am guilty of this) when in actuality all numbers go to the same place. Underneath those phone numbers you will see the locations they are trying to target. This plumber has every location covered in Philadelphia except for North Philadelphia. There is a high concentration of blacks that live in this particular area and they have one of the lowest household incomes in the city. I would like to find out if any other neighborhoods/zip codes in the city have equal or lesser household incomes than those in North Philadelphia.
