Methods and Samples: The research design and instruments were identical at the two cites. The number of participants was 139 and 151 respectively. Results: The Icelandic sample had a lower level of educational attainment, a higher ratio with working class back-ground, a higher retirement age, a higher level of single living participants, and more often received home health care. They also had fewer close friends, provided a lower level of support to their children, and, to a lower extent, thought their income met their needs. The Swedish participants reported a higher divorce rate, a lower number of children, siblings, and grandchildren, a higher level of satisfaction with family contacts, and a higher level of loneliness. Summary: Many significant differences concerning demographic and social network variables were found between the two samples. Possible macro-social and cultural explanations of the differences are discussed
