No they don't Clint. Do you know how to positively identify the ethnicity or country of origin of every Asian Indonesian polynesian?
What about the different native American tribes can you identify those? Do you think you could properly identify each different type of crab on a crab boat by simply calling it a crab and bringing it to the fishery as such?
The majority of people might see an American bulldog mix, boxer mix, mastiff, rottweiler, catahoula, Staffordshire, American pit, cane corso, and any number of breeds and report it as a pit bull.
The point is that the only data kept or found on bites come from public reports, media or police reports. They have to be reported and when the breed doesn't exist yet is found on the majority of reports, the report is flawed and incorrect but that doesn't remove the report or correct it.
Also, you being a person who's career (can't think of what to call it but I hope you get my meaning) or profession is largely the result of science and testing and such, I would lluke to think you'd rely on the results of all the testing done on this, all having the same results. There is zero evidence that there is a genetic predisposition to aggression in any of the domesticated breeds.
