Here is the original
Florida Today report cited in the Associated Press
article I discussed in
this previous post, about media coverage of the impact of the repeal of Florida's motorcycle helmet law.
Florida Today actually did a marginally better job of reporting the data accurately than the Associated Press did. Here's the key part:
A FLORIDA TODAY analysis of federal crash statistics for Florida revealed a drastic upward spike in motorcycle fatalities involving riders without helmets since the repeal took effect. Annual statewide "unhelmeted" fatalities mushroomed from 22 deaths in both 1998 and 1999 to 250 deaths in 2004, the most recent data available.
That represents an 11-fold increase. By comparison, 270 Florida riders without helmets were killed during the entire 1990s, when the practice was illegal.
But by the same token, motorcycle registrations shot upward 87 percent since the helmet repeal took effect. Annual registrations increased from 238,229 to 445,896 from 2000-04, the Florida Department of Highway Safety and Motor Vehicles reported.
Total Florida motorcycle fatalities have increased statewide since the helmet law's repeal. The yearly death toll leaped from 259 in 2000 to 432 in 2004 a 67 percent jump National Highway Traffic Safety Administration data shows.
The
Florida Today story seems to indirectly acknowledge that it's the legalization of helmetless riding that's responsible for the rise in helmetless deaths. It also reports the actual data for the rise in motorcycle registrations, and pretty much admits (with the phrase "But by the same token...") that this increase is responsible for the rise in total deaths.
However, it stops short of admitting that registrations have increased much more rapidly than deaths. Using data from
this chart and
this chart from the
Florida Today article, I calculate that there were 139 rider deaths per 100,000 motorcycle registrations in 1999, the year before the helmet law was repealed. Yet in 2004, the last year for which full data are available, the rider death rate had declined to just 97 per 100,000.
If you ask me, that's the real story: Why has riding a motorcycle in Florida apparently gotten
safer since the repeal of the helmet law? There are lots of possible explanations bikes are becoming more reliable, riders are getting more training, people are registering bikes yet not riding them very much but the reporter seems unwilling to even ask the question.
FOLLOW-UP:
Errors like this have a way of spreading as one newspaper cites another, growing less and less accurate in the process. For example,
here's a self-righteous editorial from the Walla Walla, Washington
Union-Bulletin, which cites the
Florida Today report with regard to the increase in rider deaths, but
doesn't even mention the much larger percentage increase in bike registrations.
