Integrated Management and Operation of the Health and Welfare Data Portal System (2025): Strategies for Advancing a User-Centered Data Platform Lee Hyejung; Cho Yongchan; Kim Min-Seok; Jung So-Hue; Lee Ki-ho

The purpose of this study is twofold: first, to improve the Health and Welfare Data Portal into a more intuitive and user-friendly platform; and second, to expand the openness of health and welfare statistical information and data to enhance their usability. This study examined cases of domestic and international data portals. Regarding the 2025 operations of the Health and Welfare Data Portal, the study proceeded with three main topics: first, the status of portal visits, content usage, and microdata provision was identified; second, a satisfaction survey was conducted with 1,000 users to analyze service satisfaction and improvement needs, such as search accuracy; and third, summarizing the 2025 portal restructuring―including new survey data integration and UI/UX redesign―while proposing future tasks such as continuous content development and quality management.

Drivers of Wealth Disparity and Policy Implications Kim Seonga; Lee Jumi; Park Hyungjohn; Han Solhee; Han Su-jin

This study examines the extent and structural drivers of wealth inequality in South Korea and proposes policy measures to mitigate the widening asset gaps. The analysis reveals that asset disparities are shaped by complex interactions among life-course trajectories, asset composition, debt utilization, and the impact of intergenerational transfers through inheritance. From a life-cycle perspective, a coordinated policy approach is required that integrates social and tax policies, prioritizing support for low-and middle-wealth groups.

A Study of Assessment of Social Cohesion Status with Policy Implications (XII): The Multidimensionality of Changes in Social Perceptions Cheong Sejeong; Kang Shin-Wook; Kim Ki-tae; Oh Sungjae; Woo Sunhee; Lee Soohyun

Amid a global deterioration in democracy-related indicators, concerns over social cohesion have intensified alongside growing claims that political conflict increasingly intersects with generational and gender divides. Against this backdrop, A Study of Assessment of Social Cohesion Status with Policy Implications (XII), now in its twelfth year, builds on the traditionally discussed concept of social cohesion while addressing the need to expand and refine this concept in response to changing political and social conditions. Drawing on survey data and a wide range of data sources, the study seeks to diagnose the current state of social cohesion (Chapter 3).
Chapter 4 aims to identify strategies for enhancing social cohesion by focusing on ways to promote social participation―one of its core components. To this end, data from 2014 to 2025 (excluding 2020) were compiled into pooled cross-sectional datasets, on which logit and regression analyses were conducted. Chapter 5 examines political orientations, value orientations, perceptions of the future, and attitudes toward welfare using the pooled cross-sectional data. Finally, Chapter 6 analyzes attitudes toward democracy and welfare based on the 2025 survey data.

Maternity Blues and Postpartum Depression: Empirical Analysis and Policy Implications Lee, Soyoung ; Kim, Jayeun ; Hong, Hae-young ; Lim, Jiyoung

This study investigates the current status of postpartum mental health and explores policy directions to enhance maternal well-being within the broader context of Korea’s persistently low fertility. It examines the prevalence and determinants of maternity blues and postpartum depression, analyzes their influence on mothers’ intentions for subsequent childbearing, and identifies key protective and risk factors associated with onset and recovery. The findings underscore the necessity of developing comprehensive yet individualized postpartum mental health policies that are supported by robust legal and financial frameworks. These policies should promote early intervention and continuous management through an integrated system encompassing mothers, partners, and families, thereby reinforcing the sustainability and equity of maternal mental health support.
