The table below shows the trauma sums insured selected. There are some details about the data below, but in summary you can quickly find the most commonly chosen sum: $100,000, following by $50,000, and then $200,000. Although a better interpretation might be: for the population as a whole, most people don't buy trauma. If you look at the cluster of quotes around $50,000 then most people choose much less cover than $100,000, a few choose $100,000, and the rest choose the same cover as their life sum insured.
The chart shows the value selected by for either the only client, or the first client of two, where there are more than two clients. Although the scenario may be crunched several times the value is taken from the most recent crunch, because that is expected the be the iteration closest to an application if that eventuated. It is only for crunches in the quarter to the end of March 2017 on Quotemonster, it includes trauma sums insured from any combination of benefits which included trauma.
