A meta-analytic study of the factors driving the purchase of organic food.

Interest in the consumption of organic food has steadily risen over the past two decades. Yet after considerable research addressing a range of issues related to organic food consumption no research systematically examines which factors explain consumers' perceptions and purchase of organics. Through a meta-analysis we examine factors underpinning the purchase of organic food using a sample of 124,353 consumers reported in 150 manuscripts over the period from 1991 to 2016.
