The number of children (0-14) in Korea has almost halved over the past 4 decades: from 13,2 million children in the 1975 to 7 million in 2015. Over the same period, the youth dependency ratio - the number of children and young people (aged 0-20) per one hundred people of working age (aged 20-64) - fell dramatically from 108 to 31 (OECD, 2018|i]). The growing income in Korea can be shared among a smaller number of children, which helps to explain why the child poverty rate in Korea is below the OECD average (Figure 1) and poor children today live in smaller families than only a few years ago (Yeo, 2017).
