Society of Actuaries

Traditional actuarial techniques for segmenting risks and analyzing longevity trends have relied on simpler data sets and analysis methods. With the advent of big data, increasing data sources, growing computer power, and new analytics techniques, we can highlight several places where actuaries are further refining underwriting segmentation, revealing variables that drive insurance contingencies and noting population demographics trends. Key topics to be discussed are: the use of analytics for accelerated underwriting in the US Life Insurance industry; the use of tree models to identify key variables that drive disability recovery rates; analysis of climate and economic variables that indicate trends in auto collision frequencies; and using decomposition algorithms (such as developed in Andreev, Shkolnikov and Begun, DEMOGRAPHIC RESEARCH, 2002) in studying trends in life preparancy ages in high-income populations (Hall, SOA, 2017).
