San Diego
Winner$98,657
Boston
$89,212
Median household income is $98,657 in San Diego versus $89,212 in Boston, so typical pay runs 11% higher in San Diego (about $9,445 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.

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

San Diego
Winner100 (100 = avg)
Boston
134 (100 = avg)
San Diego's crime index is 100 versus 134 in Boston (100 = national average), so citywide crime runs 25% 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. Indexes still compress a lot of reality: a calmer city has blocks you would skip, and a higher-crime city has streets that feel neighborly at 10 p.m. On the everyday test of walking from the car to the door, San Diego is the easier city. Boston can still work if you pick the right pocket. Just budget more diligence before you sign a lease.
