Determinants of Unmet Medical Demands within Single-Person Households: A Sample Selection Probit Analysis of the 2022 Community Health Survey

Abstract

The current study empirically examines the key factors affecting unmet medical demands among single-person households. The recent growth in single-person households in South Korea has raised concerns that they may be relatively disadvantaged in accessing medical services. To address this concern, this study utilizes the 2022 Community Health Survey dataset and conducts an in-depth analysis of the determinants of medical demands and unmet medical demands within this population. A two-stage model is employed to separately analyze the occurrence of medical demands and the subsequent unmet demands, distinguishing between the process of demand generation and the occurrence of unmet demands. Key independent variables include economic factors, health status, social networks, the availability of medical infrastructure in the region, and differences between urban and rural areas. The findings reveal that these variables significantly impact unmet medical demands, with systematic differences observed between urban and rural areas.
