The definition of digital poverty has not been changed since it was used at the first digital divide survey in 2000s. The objective of this study is to reexamine and redefine digital poverty targets of digital divide survey. This study examines the present state for the target of the digital divide survey focusing on Disabilities, Low-Income and Elders and then redefines digital poverty for them. The results suggest to reexamine 15 types of disabilities by the revised the Disabled Welfare Law as digital divide targets, rather than limiting to physical, brain, hearing and visual disabilities. For the low-income target, people on the second-to-the bottom income bracket as well as those on basic welfare should be included as the target of low-income people for digital poverty. The age of the elder target for digital poverty should be adjusted to sixty-five or more in the era of aging population.

The definition of digital poverty of multicultural families has not been changed since it was used at the first digital divide survey in 2012. The objective of this study is to reexamine and redefine digital poverty targets of digital divide survey for multicultural families. The results suggest to reexamine multicultural families rather than limiting to Immigrant women for digital poverty. The results were as follows. First, the current survey has been limited to the migrant women for information gap survey of married migrants. But, It is expected to increase immigrant men in the future. It should include migrant men in the marginalized target in terms of preparation for a multicultural society. Second, the current survey has been limited to the migrant women for information gap survey. But, It is expected to increase children of multicultural families. This information gap is likely to be linked to differences in education or future economic disparities for children of multicultural families. It should include children of multicultural families in the marginalized target in digital divide survey.
