^aProportions are unadjusted for sampling weights.

^bExtrapolation to all jobs was calculated by weighting each stratum-specific agreement by the proportion of all jobs observed in that stratum. For example the strata-specific agreement for the Chemist Module, Farming and Food Industry Module, and Industry Solvent Module accounted for 0.9, 18.8, and 0.3% of the extrapolated estimate, respectively. Proportions of all jobs each stratum represented are shown in Table 1 for most modules and Table 4 for the Solvent and Work Location Modules.
