Yes flightsim, pretty much, except that what you are talking about is a safety RECORD. Obviously, an aircraft could be unsafe, having never killed anyone (case in point; Concorde. Well, maybe). All aircraft have started out with a perfect safety record.
If you ARE talking about safety records as opposed to safety, how else do you measure a safety record? You can either do what the Americans do, and go down the product liability road, or you can assess the safety of an aircraft by the number of accidents it has had, and the number of resulting fatalities over the life of the fleet.
Either way, the 146 comes up smelling pretty sweet compared to any Boeing of its era.
By the way, the oil data was supplied by Mobil but quoted in the Aussie Senate report.
