Iowa type survivor curves
WebFigure 2: Hypothetical survivorship curves. Note that the y-axis has a logarithmic scale. Type 1 organisms have high survivorship throughout life until old age sets in, and then survivorship declines dramatically to 0. Humans are type 1 organisms. Type III organisms, in contrast, have very low survivorship early in life, and few individuals ... Webarea under the curve to the right of the age, divided by the percent surviving at that age. The standard survivor curves most often used with utility property are known as Iowa-type survivor curves. This family of empirical curves was developed more than 80 years ago.

WebFor the scaled curve, the scaled age increment is simply the PLife divided by 100. For publication, BCRI scaled the original Iowa curves to exactly a 100.00 year average life. For some Iowa curves, this results in a slight difference between the original Iowa curve percent surviving and BCRI’s WebIowa-type survivor curves are parametric, as opposed to formalistic, in that they were derived from empirical survival/retirement data which Winfrey collected.

The survivorship curve is a useful visualisation of the frequency distribution of the age classes of a population (Rauschert 2010) and is calculated as l x = n x /n 0, where n x is the number of individuals in the study population who survive to the beginning of age category x and n 0 is the number of newborns.
