Deaths due to eating disorders per million persons in 2012 There is little data on the percentage of people with<unk>  in general populations. Most studies conducted thus far have been on convenience samples from hospital patients, high school or university students. These have yielded a wide range of results: between 0.1% and 1.4% of males, and between 0.3% and 9.4% of females. Studies on time trends in the prevalence of<unk>  have also yielded inconsistent results. According to Gelder, Mayou and Geddes (2005)<unk>  is prevalent between 1 and 2 percent of women aged 15–40 years.<unk>  occurs more frequently in developed countries and in cities, with one study finding that<unk>  is five times more prevalent in cities than in rural areas. There is a perception that<unk>  is most prevalent amongst girls from middle-class families; however, in a 2009 study girls from families in the lowest income bracket studied were 153 percent more likely to be<unk>  than girls from the highest income bracket. There are higher rates of eating disorders in groups involved in activities which idealize a slim physique, such as dance, gymnastics, modeling, cheerleading, running, acting, swimming, diving, rowing and figure skating.<unk>  is thought to be more prevalent among Caucasians; however, a more recent study showed that African-American teenage girls were 50 percent more likely than Caucasian girls to exhibit<unk>  behavior, including both binging and purging.
