The totals at the State and division level were derived from separate tabulations based on industry rather than State detail. The sum of the State detail may not add to the division totals because of (1) independent rounding, and (2) independent corrections to the industry tabulations and State tabulations.

The figures shown with an asterisk (*) either have associated standard errors exceeding 15 percent or are not consistent with other Census series and related data. Thus these estimates may be of limited reliability. However, they may be combined with other totals into broader aggregates which are of acceptable reliability. The procedure for obtaining relative standard errors for these combined totals is discussed in Section 3 of the Introduction.

Represents zero.

(D) Withheld to avoid disclosing figures for individual companies.

(NA) Not available.

n.e.c. Not elsewhere classified.

(S) Withheld because the estimate did not meet publication standards, either on the basis of the associated standard error of estimate or on the basis of a consistency review.

1Division, State, and standard metropolitan statistical area totals include the estimates for all component industry groups or counties, regardless of whether or not separate data are shown for the individual industry groups or counties.

2The total value of shipments and cost of materials for industry groups shown include extensive duplication arising from shipments between establishments in the same industry classification. For a more complete explanation, see Introduction.

3The statistics in this report were compiled in a sample survey and are, therefore, subject to sampling variations. The possible variations from a canvass of the complete universe are measured by the standard error. The percentage standard errors shown in the columns indicate the range of difference attributable to sample fluctuations that can be expected between the estimates and comparable complete canvass totals. The estimates will differ from the complete totals by less than:

(1) The percentage shown, approximately 2 times out of 3.
(11) Twice the percentage shown; approximately 19 times out of 20.
(iii) Three times the percentage shown; almost always.

"The publication of "All industries" totals at the county level is limited to the large industrial counties (those with over 5,000 manufacturing employees) which could be shown without disclosing figures for individual companies and for which a reliable estimate was obtained. The sample for the annual survey of manufactures was not
