There is growing concern over the life quality and stability of young population, and the housing problem lies at the heart of the issue. In this paper, three hypotheses on the cause and seriousness of the problem are examined: Do parents reduce financial support or downpayment for their children households? Do the present young households face severer housing cost burden? Are the present housing purchase prices or rents out of reach for young households? Based on the Korea Labor and Income Panel Study (KLIPS) data, the present parents are still supporting their separate children households. The housing cost burden among young households is worsening in terms of Rent to Income Ratio (RIR), which is, however, much lower than that of old households. Finally, in Seoul, the young households in the 1st and 2nd income quintile can neither own nor rent the cheapest housing in the region. Similarly, the households in the 3rd income quintile cannot access the median-price housing in the region.
