Description: Presented at Living to 100 Symposium, January 2002. This paper is a first attempt to assess which group of mortality trajectories proposed by various researchers is confirmed by empirical data between the age of 110 and 115 years when the exponential trajectories on the one hand and the logistic or quadratic trajectories on the other hand have diverged sufficiently.

Description: Presented at Living to 100 symposium, January 2002. This paper proposes a standard operating procedure for testing the Gompertz assumption using yearly age-specific mortality data, and the impacts of the data collection period and population sizes on the testing results are discussed.

Description: We propose an age-shift model to modify the LC model and deal with the problem of parameters. The proposed method attains smaller estimation errors with respect to mean absolute percentage error or mean square error. We also apply the proposed age-shift model to the mortality rates of these four countries to evaluate the longevity risk in annuity products by measuring life expectancy.

Description: Presented at the Living to 100 Symposium, January 2011. This study explores increasing life expectancy by examining the basic properties of survival curves. Specifically, the author checks for signs of mortality compression, using a non-traditional approach. The results indicate that human longevity is likely to increase, at least for a while, and longevity risk should be seriously considered in pricing annuity products. Some suggestions for dealing with the longevity risk are also proposed.

Description: Living to 100 symposia are held every three years and they offer a mix of technical content, leading edge speakers on biological and societal developments and implications for society of developments in mortality. They provide insight into areas of controversy. These are multi-disciplinary discussions. This article offers some highlights from the 2020 Living to 100 focused on retirement actuaries.

Description: This is an example of male life expectancy at age 65 from the United States.

Description: With a reference to Malthus, this paper notes that the main constraint on human population in the foreseeable future is cultivable land for food agriculture. The author proposes a solution involving the use of land that is currently desert, using desalination and solar power a plan which he demonstrates can be sustainable and profitable.

Description: Gross Domestic Product (GDP) has been our chosen metric for growth since the Great Depression, but expectations are for lower GDP growth going forward than we are accustomed to. Its two components, population and productivity, face headwinds—population from a declining birth rate and longevity, and productivity from increased climate events, energy costs, global conflict and raw materials shortages. Comparing demographic results from the U.S., China and Nigeria, representing countries with varying population growth rates, illustrates the potential economic growth issues of aging populations and high dependency ratios. The demographic challenges can be turned into opportunities to broaden prosperity; productivity can be improved by providing a level playing field and helping those in the lowest socioeconomic classes find opportunities. These topics and more will be discussed and enhance foresight about them.

Description: This article contains a synopsis of the author's presentation at the 2011 Living to 100 symposium. The presentation discusses the aging of the population in India and its effect on the Indian economy.

Description: This session at the SOA 2003 Vancouver Spring Meeting presents a study of the pattern of longevity and mortality improvement in Canada with comparisons to the U.S. and other countries. The data is based on a mortality study of Canadian pensioners.
