Demographic Context of Household Change and Growth Components in South Korea: 2000~2020

Abstract

This study analyses the demographic context and factors of household change over the period 2000-2020. In particular, the increase in the number of households is decomposed into headship rate changes and changes in population distribution to understand the demographic context of household change. The standardization-decomposition analysis shows that approximately one-third of the household growth over the past 20 years is due to the increase in the propensities of persons to form separate households, and roughly two-thirds is due to population growth and changes in the age and marital status distribution. The effect of the increase in the headship rate was strongest among widowed/divorced persons (especially women) aged 65+ and never-married persons in their 20s. On the other hand, the effect of population distribution is more pronounced in the middle-aged and elderly population aged 50+, reflecting the impact of aging baby boomers.
