Description: The influenza pandemic of 1918-20 is recognized as having generally taken place in three waves, starting in the northern spring and summer of 1918. This pattern of three waves, however, was not universal: in some locations influenza seems to have persisted into or returned in 1920. The recorded statistics of influenza morbidity and mortality are likely to be a significant understatement. Limitations of these data can include nonregistration, missing records, misdiagnosis, and nonmedical certification, and may also vary greatly between locations. Further research has seen the consistent upward revision of the estimated global mortality of the pandemic, which a 1920s calculation put in the vicinity of 21.5 million. A 1991 paper revised the mortality as being in the range 24.7-39.3 million. This paper suggests that it was of the order of 50 million. However, it must be acknowledged that even this vast figure may be substantially lower than the real toll, perhaps as much as 100 percent understated.

Description: This SOA report provides an overview and analysis of the mortality models, theories and trends contained in the papers presented at the past four international Living to 100 symposia.

Description: This abstract describes a paper that shows that by modeling the time series of mortality rate changes rather than mortality rate levels, human mortality can be better modeled.

Description: The Preferred Mortality Valuation Table Team prepared this presentation for the June 2008 NAIC LHATF Meeting. The Adobe Acrobat file on the SOA website for experience studies contains the presentation.This Excel workbook is a tool the valuation table team is using to develop values relating to margins for the new valuation mortality table. The purpose of the workbook is to evaluate different margin formulas and valuation tables. Also used for analysis of mortality margins on Valuation Basic Tables.

Description: This article lists participating companies and countries with the International Experience Study and describes the process of adding additional countries to the study.

Description: Effective risk management of a portfolio demands accurate and succinct models which explain the main risk factors. We look at the various requirements we demand of a model, and find that they can all be met with an import from medical statistics: survival models.

Description: The article discovers that mortality is higher for females than for males at higher ages, and suggests "stress" as the explanation. It then discusses mental illness research, including recovery therefrom.

Description: This report provides information on other mortality and morbidity data sources to consider. Some of these data sources are rich and complex. This report provides an overview of the data sources’ characteristics and a roadmap to delving into their details.

Description: This article discusses the project to develop a new Credit Life Insurance valuation standard.
