Analytic System for the Measurement of Relative Fire Hazards

Also known as Dean Schedule. A method (now obsolete) of rating fire insurance risks developed by A. F. Dean (Chicago, 1901). Geographically, much of the country is rated under this schedule. Dean described a standard unoccupied risk for which a base rate was named depending on overall territorial factors. Each individual hazard or factor (construction, area, damageability, occupancy, exposure, etc.) that appeared in the risk added or subtracted a percentage of the base rate to produce the specific rate. A successful, logical method which has contributed much to insurance thinking and practice.
