Marketers can segment according to geographic criteria—nations, states, regions, countries, cities, neighborhoods, or postal codes. The geo-cluster approach combines demographic data with geographic data to create a more accurate or specific profile.[1] With respect to region, in rainy regions merchants can sell things like raincoats, umbrellas and gumboots. In hot regions, one can sell summer clothing. A small business commodity store may target only customers from the local neighborhood, while a larger department store can target its marketing towards several neighborhoods in a larger city or area, while ignoring customers in other continents. Geographic Segmentation is important and may be considered the first step to international marketing, followed by demographic and psychographic segmentation. The use of national borders is the institutional use of geographic segmentation, although geographic segments may be classified by identified geological regions.
