Median household income is $108,077 in San Diego versus $97,344 in Boston, so typical pay runs 11% higher in San Diego (about $10,733 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.

Boston
147 (100 = avg)
San Diego's crime index is 106 versus 147 in Boston (100 = national average), so citywide crime runs 28% 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.
