Description: In most countries in the developed world and also in a number of other countries, the population is aging. What impact will a changing demographic structure have, if any, on economic factors such as growth and inflation? This question is of vital importance to actuaries who use demographic and economic projections in the pricing and valuation of products, design of risk management solutions, and in opinions regarding the sustainability of social programs. This research report, funded by the Society of Actuaries (SOA), provides background on research in this area and offers insights that may be of use to practicing actuaries.
