Objectives This study aims to analyze recent research trends related to NEET (Not in Education, Employment, or Training) youth and to provide implications for future research and support for NEET youth. Methods To analyze research trends related to NEET youth, a total of 58 papers, consisting of 43 domestic journal articles and 15 dissertations related to NEET youth published over 17 years from 2008 to 2024, were selected for analysis. The criteria for analyzing research trends were set in four areas: basic information, research subjects, research methods, and research topics. Results The study showed a significant increase in the number of journal articles and dissertations after 2015. Second, in terms of research subjects, studies focusing on non-job-seeking NEETs accounted for about 63%, followed by studies on mixed-type NEETs and job-seeking NEETs. Third, in terms of research methods, quantitative research was most commonly used in both journal articles and dissertations. The most frequently used analysis methods were overall scale estimation using statistical data and quantitative analysis of determinants leading to NEET status. Finally, regarding research topics, studies on the causes and influencing factors of NEET occurrence and the types and characteristics of NEET youth were the most common in both journal articles and dissertations. However, there is a greater need for research on support programs for NEET youth and measures for preventing and overcoming NEET status. Conclusions Based on the results of this study, discussions and implications for follow-up research and support for NEET youth were described, and recommendations for future research were made.
