Geographic segmentation divides the market into geographical units such as nations, states, regions, counties, cities, or neighborhoods. The company can operate in one or a few areas, or it can operate in all but pay attention to local variations. In that way it can tailor marketing programs to the needs and wants of local customer groups in trading areas, neighborhoods, even individual stores. In a growing trend called grassroots marketing, marketers concentrate on making such activities as personally relevant to individual customers as possible.
