This report describes an assessment of the degree of representativeness and comprehensiveness of the 1995 Road Accidents in the Private Accident Registration System (VIPORS), the second year of registration. It was determined whether victims in the thirteen hospitals that formed part of the VIPORS random sample are a good reflection of victims throughout hospitals in the Netherlands. For this purpose, the Transport Research Centre, Department for Statistics and Data Management (AVV/BG) database and the Dutch National Medical Registration (LMR) database were used. The degree of correspondence was very high, despite the fact that the VIPORS hospitals do not show a nationwide distribution across the Netherlands. Next, the 1995 VIPORS data were compared with similar data from: (1) the 1994 AVV/BG database; and (2) the 1994 LMR database. It is concluded that the VIPORS database gives a sufficiently representative impression of the actual nature of road accident victims who report for treatment to the First Aid hospital departments in the Netherlands. Using an `incrementation' methodology derived from the approach used by the Private Accident Registration System (PORS), the population size of road accident victims in the Netherlands can be determined.
