Koran estimated the prevalence of compulsive buying to be 5.8% in a national household survey conducted in 2004 on 2,513 18+ year-old adults75. In logistic regression analyses, ethnicity was not a significant predictor of compulsive buying status. In a meta-analysis examining 63 empirical studies of consumer impulse buying from 1978 through 2012, six studies investigated ethnic differences and the results were inconclusive76. These six individual studies were not specified, however, and could not be located.
