J114 Papermaking and Coating Control Operators
J143 Papermaking and Finishing Machine Operators

Data for J114 Papermaking and Coating Control Operators and J143 Papermaking and Finishing Machine Operators should be used with caution. There is some overlap of responses coded to these two groups as respondents do not always provide enough information to allow coders to distinguish between them.

J191 Machining Tool Operators
J192 Forging Machine Operators
J194 Metalworking Machine Operators
J196 Other Metal Products Machine Operators
J197 Other Products Machine Operators

Census data for these occupation groups should be used with caution. A high number of vague responses related to machine operators in car parts manufacturing has resulted in an over-estimate for occupation group J191 Machining Tool Operators. When compared with 2001 estimates, fluctuations in the data suggest inconsistency in the coding of these occupation groups between 2001 and 2006. In particular, J197 Other Products Machine Operators shows a relatively large decrease between 2001 and 2006. For these reasons, census data users may prefer to make historical comparisons at the three-digit minor group level for these occupations.
