San Diego's crime index is 106 versus 183 in San Francisco (100 = national average), so citywide crime runs 42% 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. San Francisco can still work if you pick the right pocket. Just budget more diligence before you sign a lease.
