Abstract
This report, as published in Verkeerskunde 30 (1979-05) No. 5, is a shortened version of Niet geregistreerde verkeersdoden. (See B 15247: Road accident casualties in the Netherlands dying later than 30 days after the accident are not registered as road deaths. The SWOV has made a comparison of CBS data and data from hospitals, in order to estimate the number of "road deaths after 30 days". The result of this comparison is that the number of road accident casualties dying later than 30 days after the accident increases the official CBS number of road deaths by c.a. 3%.).
