People who live on the West Coast are more likely to buy locally-grown food than people in most other parts of the country. That's according to a study tracking the growth of local-food sales.

"We found that the West Coast showed up much higher in terms of local food sales than before."

Sarah Low is an economist with the U.S. Department of Agriculture who co-wrote the study. She attributes the increase in sales to farms selling their products beyond just farmers markets.

"They're marketing directly to grocers or directly to restaurants. Whereas local food producers in the Northeast and mid-Atlantic are much more likely than on the West Coast to market through farmer's markets, roadside stands and other direct to consumer outlets."

Farms on the West Coast accounted for nearly 25% of the nation's local-food sales.
