San Francisco neighborhoods at a glance
What the Census says about the ZIP code areas we track. ZIP boundaries don't line up exactly with neighborhood lines, so each row describes the area around a ZIP. Broadband figures count households with a broadband subscription from any provider. They are not Xfinity coverage figures.
