  registered because they resulted in fewer than four days of absence:*‘Around 37% of accidents at work*
  *in the EU result in fewer than 4 days’ loss of work.’*154 .In the estimate above the figures are in a similar 
  range. The**LFS surveys also reveal strong differences between occupational groups**. The ISCO 
  groups 1-3 have less than half the accidents compared to groups 6-7 and 8-9.155
