The number of people killed or injured per hour walking is a common way of expressing risk for pedestrians. A complicating factor, as discussed above for drivers, is that older people are more fragile; a collision that may have caused little harm for a young person could nevertheless hurt someone who is older, and hence more fragile.
The following chart shows how the risks vary over age groups and between men and women.
Male pedestrians are consistently more liable to be injured when walking than females. Such differences in risk suggest that, as pedestrians, males behave differently - leading to higher risk. Predictably, the youngest school-age children are very much at risk - particularly boys aged 5 to 9. The high risks for older pedestrians partly reflects their fragility but also indicates that they can no longer cross the road as safely since they are slower to react and less likely to be aware of approaching vehicles.
The following graph on pedestrians injured annually, per million hours walking, shows there has been a fairly consistent improvement in pedestrian safety between 1989/90 and 1997/98. This may indicate a combination of improved behaviour by pedestrians, improved driving behaviour, and improved pedestrian road environment - including the provision of better footpaths, separation of pedestrians from vehicles, and better crossing facilities.
