Median household income is $108,077 in San Diego versus $61,953 in Philadelphia, so typical pay runs 74% higher in San Diego (about $46,124 more household income a year).

Winner106 (100 = avg)
San Diego's crime index is 106 versus 261 in Philadelphia (100 = national average), so citywide crime runs 59% lower in San Diego. That gap is meaningful day-to-day. It affects whether you feel comfortable walking at night, leaving your car on the street, or letting kids play outside unsupervised.

Philadelphia can still work if you pick the right pocket. Just budget more diligence before you sign a lease.
