Almost all men (98.5%) and women (98.1%) below age 35 have attained at least upper secondary education in Korea, which is above the OECD average (Figure 4). For men, this proportion is 10 percentage points higher than for their older counterparts, and for women this is almost 15 percentage points higher than for the older generation aged 45 to 54 years. The increase in female employment is a factor contributing to the rise in the number of couples with two earners, whose proportion has increased by 4 percentage points since 2006. Yet, a large minority (43%) of two parent families have only one or no parent working. Source: OECD Employment database and Income Distribution Database.
