This report updates the 2004 Projections released in April 2005, which were based on a statistical procedure using incomplete/partial data. This report also compares fatality counts and injury estimates resulting from motor vehicle traffic crashes occurring in 2004 with counts and estimates from final 2003 files. Counts and estimates are based on Fatality Analysis Reporting System (FARS) and NASS General Estimates System (GES) files, as indicated in the sources listed on page 4. The fatality counts for 2004 will be updated based on final FARS files released next year. Data from 2003 are final and will not be updated again. Since the fatality counts from FARS data are based on a census of fatal traffic crashes, the fatality data contained in the following tables are not subject to sampling error. However, the injury estimates from NASS GES data are based on a nationally representative sample of policereported crashes and hence are subject to sampling errors. The changes in injury data between 2003 and 2004 that are statistically significant (where applicable) are indicated in the respective tables with a foot note. (Author/publisher)
