Actuarial data are the statistics used to calculate various sorts of risk that insurance companies insure people against. If you want to know how likely it is for your car to be stolen, there is surely some actuarial data that could give you an answer.

Actuarial science includes statistics, probability, mathematics, and economics, and the people trained in it are called actuaries. When you buy a homeowner's insurance policy, for instance, the insurance company calculates how much they’ll charge you by consulting the actuarial data, which tells them how likely it is that something will happen to your house (based on how old your house is, where it’s located, the building materials, your credit rating, and lots of other factors).
