Abstract

In a recent study (3) by the author on trends in motor vehicle fatalities, extrapolations were made for 20 years hence. The trends indicated a definite reduction in traffic death rates (deaths per 100 million vehicle miles). The rates and trends were based on data for the 20-ycar period, 1935-1954. The data used were from official figures published by the National Safety Council (2). As stated, rates are decreasing, yet we do find annual fluctuations sometimes greater than expected in each state and for the total U.S. for which it is at times difficult to give a satisfactory explanation. In certain instances a particular state may show up very well in its rate for one or two years then regress. When its rate is compared to the total U.S. rate for the same year, it may not be as favorable as it would first appear. The reverse may also be true. The present study was designed to test the hypothesis that apparent trends in fatality rates are not always indicative of progress or regress being made.
