This study attempts to identify consumption expenditure patterns of babyboomer households according to income quintile using cluster analysis, find out the socio-economic characteristics of the identified clusters, and compare the patterns of different groups. This study uses the data provided by Korean Retirement and Income Study published in 2015. Among total sample 6405 households, 1558 households are babyboomer households. For this study, we classify five babyboomer groups according to income quintile and employ 10 consumption categories of the 2015 KReIS. The 1558 babyboomer households undergo an analysis using statistical package for social science (SPSS) 23.0, specifically k-means cluster analysis. Four consumption patterns are identified for each number of person groups. First, the result shows the differences in the socioeconomic characteristic and the shares of consumption category according to babyboomer households’ income quintile. Next, the main finding is that four different consumption expenditure patterns are identified for each income quintile. In addition, there exists together consumption expenditure patterns(fodd-dominated, housing-dominated, health-dominated) similar to elderly households’ consumption expenditure patterns and consumption expenditure patterns(educationdominated, others-dominated) inherent in babyboomer households.
