“…GIS methods are widely used to examine issues related to food availability and access (see for example, Ghirardelli, Quinn, & Foerster, 2010;Kirkpatrick & Tarasuk, 2010;Rose, Bodor, & Rice, 2011). The choice of demographic characteristics mapped follows from the literature on organic food consumers, which finds that, after accounting for income and other factors, consumers with higher levels of education are more willing or likely to purchase organic products (Dettmann & Dimitri, 2010;Fotopoulos & Krystallis, 2002;Krystallis, Fotopoulos, & Zotos, 2006;Magnusson, Arvola, Koivisto Hursti, & Åberg, 2001;O'Donovan & McCarthy, 2002;Zepeda & Li, 2007). Research has yielded conflicting results on the impact of income and race on the likelihood of buying organic food (Durham, 2007;Govindasamy & Italia, 1990;Loureiro, McCluskey, & Mittlehammer, 2001).…”
