This study analyzes the determining factors of the digital divide index in married female immigrants based on panel data from the National Information Society Agency (2016). There were 287 participants, all of whom owned a smartphone. The study divided the consumer groups into three age groups: 20-29, 30-39, and 40-49 years. SPSS 19.0 was used to statistically analyze the results. The findings of the analysis were described using frequency, descriptive, cross-tab, ANOVA, correlation, and multiple regression analysis. The findings of this research are as follows. First, nationality, acquisition of Korean nationality, and duration of living in Korea were significantly different among the three groups. Second, digital competency and online service usage were also significantly different among the three groups. Third, PC usage ability, mobile usage ability, and diversity of online usage significantly influenced the digital divide index in all age groups. Fourth, residential duration in Korea significantly decreased the digital divide index for groups in their 30s and 40s. Fifth, Loneliness significantly increased the digital divide index for groups in their 20s. Sixth, depression significantly increased the digital divide index for groups in their 30s. The study will help to further understand age-related differences and the digital divide of married female immigrants.
