Relative risk

\ˈrɛlətɪv\ \rɪsk\

In the context of mortality risk, relative risk refers to the increased (or decreased) chance of dying of a certain group compared to another group.

To calculate the relative risk, an Actual/Expected (A/E) ratio of experience is calculated for the two groups in relation to some standard base assumption. The relative risk is then the ratio of the two A/E figures. A relative risk greater than 1 signifies a greater chance of dying, whereas a relative risk less than 1 signifies a smaller chance of dying.
