Based on this data, we seek to identify what are the links, if they exist, between specific demographics (e.g. marital status, income, number of children, etc) and purchase patterns. In other words, we would like to see how "easy" it is for retailers to infer a specific profile of their customers based on what they buy. Of course, this would lead to targetted marketing. In other words, we want to evaluate how much of a target we, as consumers, actually are.
