Differences in perception of organic and conventional foods matter to food suppliers and retailers. Using survey data collected from 1,100 female residents of seven urban centers in Korea this study applies the logit technique to identify consumer and household characteristics that influence the perception differences regarding six attributes. Results indicate the importance of household income with regard to organic food preference and the opposite effect of education. Perceptions also differed across locations, while the effects of other characteristics varied in case of the six attributes. Food marketers must account for income, education and location of consumers to plan sales strategies.
