Description: This article discusses the sources of the information in the Social Security Death Master File and the potential utility of this information for demographic studies of centenarians and near-centenarians.

Description: The article provides a summary of key issues presented at the 2023 U.S. Living to 100 Symposium focused on the interests of retirement professionals and retirees. It provides an overview of the subjects covered. The discussion focused on the well-being of retirees and the development of the retirement system. It is focused on late-in-life issues and having the best life possible during that period. It balances technical and lifestyle issues, with an emphasis on mortality and longevity trends and influences. Some of the topics discussed include the impact of COVID, climate, housing, and age-friendly communities. The Elder Tech Symposium was merged into Living to 100 and includes discussion of a variety of technology approaches to improve lives and simplify support. The symposium recognized that the decisions needed and concerns during retirement are different later in life, particularly as people decline.

Description: Presented at Living to 100 symposium, January 2011. Using data from Social Security's Death Master File, this study shows that mortality deceleration in humans observed at advanced ages may be an artifact caused by age exaggeration, data heterogeneity or use of improper estimates of hazard rate. The phenomenon of mortality deceleration at older ages vanishes for datasets of higher data quality.

Description: In this project the researchers explored the new opportunities provided by the ongoing revolution in information technology for studies of exceptional human longevity. Methodologies and interpretation of the results were presented.
