What is the difference between real and registered numbers of casualties?

With regard to the number of casualties we distinguish between the real number and the registered number of traffic casualties.

The real number of serious road injuries is not known precisely, because not all traffic casualies are registered by the police, hospitals or other organizations of institutions. The real numbers in our tables have been determined by comparing the registered numbers from twe sources and estimating the real numbers by using a set prcedure.

The real number of road deaths, on the other hand, is entirely based on registrations.
