As another data point, there were no deaths during the construction of London 2012 Olympic Park: http://www.hse.gov.uk/press/2012/hse-olympics-research.htm http://www.hse.gov.uk/press/2012/hse-olympics-research.htm There was a single death during the construction for the 2010 Winter Olympics in Vancouver, and 10 deaths during construction for the 2008 Beijing Olympics. http://constructiondatacompany.com/olympics-world-cup-construction-worker-deaths/ http://constructiondatacompany.com/olympics-world-cup-constr... (As you speculate for Sochi, there may also be reporting issues for the Beijing Olympics, but that is nothing but speculation on my part. I don't believe that the same could be said of the construction projects in UK or Canada.) There is something _really_ wrong going on in Qatar.
