The purpose of this study is to examine the consumer competency of women in their 20-40s after consumer competency is classified into consumer knowledge, consumer attitude and consumer skill. Since these components can show differences based on the areas of consumption life, the areas of consumer competency are classified into financial management areas, trading areas and consumer citizenship areas. The differences in consumer competency based on marital status and the differences in variables affecting consumer competency by marital status are identified. The types of consumers are classified and characterized based on consumer competency and marital status. This sentence can immediately follow the previous one rather than start a new paragraph.
