A new study says the average San Francisco Bay Area household spends so much of its income on housing and transportation, that here's not much money left for other basic needs.

A report by the Urban Land Institute found area households spend on average $41,420 per year, or about 59 percent of the area's median household income, on housing costs and getting around.

The study released Wednesday says the region's high transportation and housing costs leave many residents with insufficient resources for health care, education and food.

The report says costs in the nine-county area vary from 54 percent in Santa Clara County to 66 percent in Sonoma County.

The study was released to coincide with The Urban Land Institute's annual fall meeting this week in San Francisco.
