What this means for your life

Median household income is $98,657 in San Diego versus $66,296 in Louisville, so typical pay runs 49% higher in San Diego (about $32,361 more household income a year). Higher median income usually signals a stronger local job market and better negotiating leverage on salary. Remote workers should weigh this against cost of living rather than treating it as a direct personal benefit.

Louisville can still win if housing is cheap enough to offset the weaker median or if your specific role already pays well there.

What this means for your life

San Diego's crime index is 100 versus 194 in Louisville (100 = national average), so citywide crime runs 48% 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.

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