í Product classes (5-digit codes) and product groups (4-digit codes) are assigned to the industry to which they are primary. Products which are primary to 2 or more industries are split according to the industry code of the establishment producing them. (See text above.)

Represents for each numerically coded product class or group the total value shipped by all producers in all industries.

The 4-digit product group represents the total shipments by all producers of the products assigned the code with the same first 4 digits. For products primary to more than 1 industry, only the amount produced by plants with the same industry code is included. Thus, the total value of products of meatpacking plants includes all fresh meats but only those prepared meats (20116, 20117, 20118) processed in plants classified in 2011. It does not include such products made elsewhere (20136, 20137, 20138).

The total value of all primary products shipped (4-digit product codes) in this table must be distinguished from the total value of shipments of the corresponding 4-digit industry. The industry value of shipments applies to plants classified into that industry and includes value of all of the primary products (products with the same first 4 digits as the industry code), secondary products (products with codes different from industry code), and miscellaneous receipts. (See the definitions of industry value of shipments appearing in tables 2, 5, and 6.)

Company affiliation is determined from census reports and public records. The value of shipments of products falling within each 5-digit class or 4-digit group was aggregated for plants under common ownership and company totals derived to determine the largest producers. Thus, the same company may contribute to total value of shipments in more than 1 product class or group.

By definition, this product class is limited to the products produced by establishments classified into the industry having the same code as the first 4 digits of the product code. Appreciable amounts are also made in the other product classes referred to in the product description. The total value of shipments and the percent of large companies shown here are based exclusively on the products primary to this industry.

It was feasible to combine some product classes and compute the shares of the largest companies of this combined figure. Table 4A contains the list of product classes with products primary to more than 1 industry which have been combined. Ratios based on combined 4-digit totals could not be readily constructed.

Process cheese made from natural cheese produced in the same plant is included in product class 20220; process cheese made from purchased natural cheese is included in product class 20252.

Individual products primary to other industries were included in the published totals of this product class in order to avoid disclosing figures for individual companies. Percentage share of this total accounted for by large companies is not available.

Excludes frozen soups which are included with product class 20322, Canned and Frozen Soups.

Total value of shipments has been omitted because of extensive duplication resulting from the fact that some of the products are used as materials, parts or components in the manufacture of other products in the same classification.

By definition, this product class includes only products produced by establishments classified in the same industry. However, separate figures cannot be shown. See table 4A for value of such products shipped from all establishments. See also footnote 4, above.

16 Ratios for the 20 and 50 largest companies not available. The total value of shipments and ratios for the 4 and 8 largest companies have been recomputed to exclude receipts for contract and commission work.
