Description: The first objective is to highlight the key trends and projections that describe the magnitude and scope of the aging world in the 21st century. The second is to identify some of the key issues that countries in the developed and developing world will have to face as a consequence of population aging. The third objective is to emphasize the triumph and opportunities of an aging world, providing a counterpoint to the prevailing notion that the aging of societies is a catastrophe, leading only to undue burden on future generations.

Description: This paper is the final report in a project commissioned by the Society of Actuaries Social Security Committee. The paper considers a variety of possible risk classification factors that could be used in estimating the value of any mortality based benefit for retirees. As many countries consider mandatory individual retirement accounts as their answer to a secure Social Security system, the question arises as to whether all workers can get true 'market value' annuities when they retire. It is clear today that private sector life annuities are priced assuming that the applicant is healthy-very healthy. Very little underwriting or risk classification now exists in the individual annuity marketplace. This paper reviews 45 recent research papers that look at factors that affect mortality after retirement. In particular, factors that seem to be important in predicting retirement mortality include: age, gender, race and ethnicity, education, income, occupation, marital status, religion, health behaviors, smoking, alcohol, and obesity. For each factor, this paper gives highlights relative to the named factor of the impact expected from that variable as described in the 45 reviewed research papers.
