Methodology

Workers in each trade sector are identified using the 2013 census. Only those in trade roles are included. Work-related ACC claims made by these workers within three years before or after the census. Because the census only gives a workforce at a point in time, we must choose a window around the census that is large enough to contain a significant number of claims, but small enough that not too many of the claims are made while the worker is in a different industry.
