초록

이 연구는 청년 삶의 만족도를 높일 수 있는 방안을 모색하고자 청년의 삶의 만족도에 영향을 미치는 요인들을 탐색하고자 수행되었다. 이를 위해 한국청소년정책연구원의 '2021 청년 사회·경제 실태조사의 데이터를 활용하여, 2021년 기준 만 18세~34세 청년 2,041명을 연구대상으로 하였다. 청년 삶의 만족도에 영향을 미치는 다양한 변수를 탐색하기 위해 랜덤 포레스트 방법을 적용하였다. 분석에 활용된 변수는 인구·사회학적 요인과 심리·정서를 포함하는 요인으로 총 21개이다. 랜덤 포레스트를 적용한 청년 삶의 만족도에 영향을 미치는 변수들을 탐색한 결과는 다음과 같다. 첫째, 분석에 투입된 요인 21개의 예측변수는 모두 청년 삶의 만족도에 영향을 미치는 것으로 나타났다. 둘째, 청년 삶이 만족도에 가장 큰 영향을 미치는 요인은 '직업가치관'으로 나타났다. 셋째, '정치적효능감', '기성세대인식'과 같이 청년들의 사회에 대한 인식도 청년들의 삶의 만족도에 영향을 미치는 변수임을 확인할 수 있다. 이러한 연구결과를 바탕으로 청년 삶의 만족도에 영향을 미치는 변수들을 설명하고 논의점을 제시하였다.

This study was conducted to explore the factors that affect youth life satisfaction in order to find ways to increase their life satisfaction. For this purpose, we utilized data from the National Youth Policy Institute's '2021 Youth Socio-Economic Survey' to study 2,041 youth aged 18-34 as of 2021. The randomForest method was applied to explore various variables that affect youth life satisfaction. A total of 21 variables were analyzed, including demographic and socio-demographic factors and psychological and emotional factors.The results of exploring the variables affecting youth life satisfaction using randomForest are as follows. First, all 21 predictors were found to have an impact on young adults' life satisfaction. Second, the most significant impact on youth life satisfaction was found to be 'work values'. Third, it can be seen that young people's perceptions of society, such as 'political effectiveness' and 'perception of older generation', are also variables that affect youth life satisfaction. Based on these findings, the variables affecting youth life satisfaction are explained and discussion points are presented.
