The cost of these “cramming-schools” is remarkably high amounting to about 18% of median household income per student (Statistics Korea, 2017[si). Poor households often overspend on the education of their children: for example, 16.5% of poor Korean households spend at least 30% of their income on children’s education, compared to an average of 5% for households with higher incomes (Yeo, 2017(6]). Housing costs are also increasing in Korea but the dataset does not allow for the measurement of its effect on the standard of living of children in poor families.
