Korea is expected to turn into an aged society in 2018 with the old population composing 14.3% of its total population. Drastic increase of old population rate brings out burden on Korean society and hinders its sustainable development without appropriate coping policies. Identification of older persons' needs and collection of objective information and data are prerequisite to developing effective policies for fulfilling their needs, particularly for single older persons, women older persons, and older persons in rural areas. Using the raw date from 2004 Living Profile and Welfare Service Needs of Older Persons, this study aims to identify welfare needs of older persons and to provide effective welfare policies for this population, particularly focusing on older women, older persons in rural areas and single older persons. Analyses were conducted in four areas of older persons' welfare needs; family relationship, income and employment, health and care, and leisure and social activities. Based on the main findings and their implications, this study suggested policy measures to provide income security, health security, and social participation of single older persons, women older persons, older persons in rural areas, and socially vulnerable groups.
