Isn't it great when people start bandying percentages about. Give us real numbers so we can see the real picture. ..... Total bollox. (the numbers, not necessarily the anlysis). USE. REAL. NUMBERS.
The article, no matter if you believe it or not only provides percentages but also states REAL NUMBERS !! (as such you can interpret the data effectively and easily)
Between 1991 and 2010, arm injuries rose by 145% (
660 to 1620 per year) while head injuries increased by just 20% (
590 to 706). The report also has a couple of data points from 1990, a year before the helmet law was introduced, which show that arm injuries were then lower than head injuries, with the latter being
~900.
This should be viewed in the context of a population increase (
5.9m, 1991 to 7.2m, 2010) and an increase in people riding bikes (a survey by the Australian Sports Commission in 2010 showed participation increased from
400k (2000) to 604k (2010)
The data is very clearly presented imho and includes the date period when the data was taken, its very easy to conclude from the data provided that head injuries increased from 590 in 1991 to 706 by 2010 while the population increased from 5.9million to 7.2million during the same period, this also showed and increase of people riding bikes of 4000 thousand in 2000 to 604 thousand people in 2010.. This data simply suggests that the population riding bikes is growing at a faster rate than head injury's.
How you interpt the data is up to you, but the real numbers are there for all to see.
