Median income for each tract is shown as a percentage relative to median income citywide. The blue bar represents a scale from 0 - 200% with the vertical mark in the center representing 100%, or equal to, the median income citywide. If a tract has a median income that is twice the median income citywide the blue bar will be full representing 200%.

Approximately 873,965 people live in San Francisco according to the 2020 U.S. census. 65.7% of SF residents (574,962) have a driver's license and only 54% (472,409) own a car. Yet cars dominate San Francisco's streets killing on average 30 residents each year and seriously injuring hundreds more.

This map shows where cars live in San Francisco and perhaps unsurprisingly, car ownership is lowest citywide among residents who live in the downtown core yet neighborhoods such as the Tenderloin, Union Square and Chinatown are constantly gridlocked by cars.

According to the EPA, the average passenger vehicle emits about 4.6 metric tons of carbon dioxide annually. 4.6MT x 472,409 vehicles = 4,789,471,405 pounds of environment destroying greenhouse gas emissions (GHGs) released into San Francisco's air every year. Transport generates 47% of SF's GHGs and of that, 72% is from personal driving.

The fact is far too many people continue to drive in San Francisco. According to a 2019 study by INRIX Research, 49% of all vehicle trips in SF are under 3 miles and 1 in 5 are under 1 mile. The recent proliferation of electric bicycles and other powered mobility devices in almost all cases eliminate the need to drive a car short distances, especially in a city with excellent year-round weather like San Francisco. The #1 reason people continue to drive vs ride a bike is concern for their personal safety and until San Francisco limits where vehicles can go and prioritizes building infrastructure that protects cyclists and all other vulnerable road users from cars, that is not going to change.
