Market segmentation is the process in marketing of grouping a market (i.e. customers) into smaller subgroups. This is not something that is arbitrarily imposed on society: it is derived from the recognition that the total market is often made up of submarkets (called 'segments'). These segments are homogeneous within (i.e. people in the segment are similar to each other in their attitudes about certain variables). Because of this intra-group similarity, they are likely to respond somewhat similarly to a given marketing strategy. That is, they are likely to have similar feeling and ideas about a marketing mix comprised of a given product or service, sold at a given price, distributed in a certain way, and promoted in a certain way.
