The stat says that crime is much geographically denser on average than other US cities, even after controlling for population density.

This implies that crime levels are high throughout much of the city, or extraordinarily high in pockets.

And if you live here, you know this is true. In contrast to many other cities, where crime is often concentrated in pockets, SF has high crime almost everywhere with pockets of safety in expensive neighborhoods like Pac Heights, Russian Hill, Forrest Knolls, and the outskirts.

The stat means it’s harder to escape crime in SF, unless you’re one of the privileged few.
