Fair enough - but again to put it in perspective.
15,700 out of 11 million is still a 0.14% chance - 1 in 700. One child out of a large primary school each year.
1,787 is 0.016% - just under 1 in 6000. One child out of the population (corrected for age groups) of a town the size of Eccles, Great Yarmouth, Abingdon, Great Malvern, Bletchley or Skelmersdale. Ten in a city the size of Bradford.
And those figures are combining passengers, cyclists and pedestrians. The vast, vast majority are "slightly injured". 6,243 in cars and 5,038 as pedestrians. Seriously injured: 273 in cars and 1,332 as pedestrians. 1,881 when cyclists are taken into account too - I'm not sure why the discrepancy between that and 1,787, but these are the numbers I'm looking at.
From the seriously injured + killed stats, car occupants, under 16, you're looking at chances of 0.00006% or 1 in 36,666 - about one child out of all the children living in an area the size of Reading, Northampton or Brighton and Hove.
