Thailand is a Buddhist country located on the mainland of southeast Asia, where 3-generation homes are still common. Care of older adults is primarily a family responsibility. Recent policy changes mean that all Thais are now eligible for services through the national health care system. Almost half the population has no retirement pension, leaving responsibility for support of older adults largely to extended family. Long-term care is becoming a serious concern as the population ages, women move into the workforce, and family size decreases. Thai researchers have focused on issues related to health and nutrition, income security, housing, general population aging, local and community care and services, information and education, and quality of life. There is currently no formal long-term care system.
