Striking maps reveal the huge wealth gap between San Francisco and the rest of the country

The typical San Francisco household makes about $96,677 each year. That's nearly double the national median household income of $57,617, according to the US Census Bureau.

A new interactive map - which plots average incomes in counties across the US - visualizes the enormous wealth gap between the San Francisco Bay Area and the rest of the country.

Developed by the mapping-software company Esri, the project explores patterns of wealth and poverty within American cities and the country as a whole.

Take a look at how the Bay Area compares to other metro areas around the US.
