A study by the University of California-Davis showed that in California, people with income over $150,000 per year purchase a third of electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs). People with household income of $100,000 to $149,000 account for about 20% and people with household income of $50,000 to $99,999 per year account for about 27% of these vehicles.
