A detailed analysis was made of the relationships between fatality rates and some parameters which describe, in part, the social, physical and economic characteristics of the developing country. Fatality rates were found to decrease significantly with increasing vehicle ownership, road density, gross national product per capita and vehicle density (per length of road). The fatality rates were also found to increase as medical facilities decreased (measured in terms of population per physician and population per hospital bed). Multiple regression analysis was used to show how the above parameters acting together affect fatality rates. A similar analysis was carried out on the severity indices of the different developing countries (the severity index being the proportion of all personal injury accidents that are fatal). Results similar to those described above were obtained. (see IRRD abstract no 225131 for first report - SR 270).
