Notes:

(a) All SOC2000 Major Groups are shown, as are SOC2000 Unit Groups with 10 or more actual cases reported to either OSSA or OPRA over the period 2004-2006. Figures are shown in light type if they are based on fewer than 10 actual cases.
(b) Comparisons of rates based on OPRA reports are likely to be misleading because workers in some occupations are much more likely to have access to occupational physicians than those in others.
(c) Some physicians report on a sample basis, for one month in each year. Estimated totals for these are calculated by multiplying the actual number of cases reported by 12.
(d) The rates have been calculated using the average of the Office for National Statistics Annual Population Survey (APS) denominators for the years 2004-2006.
"-" Can mean zero or rounds to zero.
(p) Provisional.
