• To examine the changes in kangaroo characteristics of young people aged 25 to 39 over the past 10 years using the ‘09Sample’ from the data for the 15th to 24th KLIPS academic conferences.

- We examined the trends and characteristics of changes of the ‘Kangaroo Tribe’ over the past 10 years, such as human and household characteristics, economic activity status, life satisfaction, and happiness.

• Over the past 10 years, the proportion of young kangaroos dependent on their parents for housing has increased.

- The proportion of kangaroos in their late 30s decreases, but the proportion of kangaroos in their late 20s to early 30s has increased significantly compared to the past.

- Recently, the proportion of people with a college degree or higher in the ‘Kangaroo Tribe’ appears to have increased significantly.

- More than 70% of Kangaroo households were found to live in their own homes, and when the equivalized income of Kangaroo households was divided into low-, middle-, and high-income groups, the proportion of Kangaroo households in the high-income class increased significantly in recent years.

- The proportion of ‘Kangaroo Tribes’ among both employed and unemployed people shows an increasing trend. In particular, the increase in the proportion of unemployed ‘Kangaroo Tribes’ is relatively steep, and since 2017, more than half of the unemployed appear to be ‘Kangaroo Tribes’.

- Among the ‘Kangaroo Tribes’, more than half are employed, and more than 70% of them are full-time workers. When Kangaroo wage earners are divided into low, middle, and high income groups based on average monthly wages, the proportion of low-income workers was 38.7% in 2012, but have declined to 17.6% in 2021.

- In perception surveys such as life satisfaction and current happiness, Kangaroos show lower satisfaction than non-Kangaroos people.

• In conclusion, among the ‘Kangaroo Tribes’, the proportion of highly educated young people with a college degree or higher is gradually increasing, and the proportion of single young people with relatively good job quality is showing an upward trend.

- Most married people are non-Kangaroos, and marital status is considered to be the main factor in escaping from the Kangaroos. The recent increase in the number of people marrying late or giving up marriage suggests that the increasing trend of young Kangaroos will continue in the future.
