In Japan, young adults have delayed the transition to adulthood in recent decades. According to the National Fertility Survey (National Institute of Population and Social Security Research), the percentage of unmarried people, both men and women aged 18 to 34 years, who were living with their parents was greater than 70% in 2015. This is the major factor in the decline in marriage rate and increase in late marriages. There are some who live with their parents until the age of 40. According to the National Fertility Survey, the percentage of unmarried people, both men and women aged 40 to 49 years, who were living with their parents was approximately 70% in 2015. Such people have less possibility of economic independence, getting married and having children. It is thought that there are two major factors. One is economic conditions that disadvantage children, such as increase in non-regular employment. The other problems are parents’ health issues and their economic instability.
However, there is little empirical information on middle-aged unmarried people who live with their parents. In this paper, I examine the characteristics of such middle-aged unmarried people using the data from Japanese Life Course Panel Survey (JLPS) conducted by the University of Tokyo’s Institute of Social Science. In particular, I focus on their employment status, individual incomes, household incomes, and vision for the future.
