SWithheld 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.
1The 1953 and 1952 "Average number of total employees" and the "Average number of production workers" are based on reported employment total totals for the payroll periods ended nearest the 15th of March, May, August, and November. For 1947, an average based on the mid-month employment for 12 months was used.
2Value of products less cost of materials, supplies, fuel, electric energy, and contract work.
The percentage standard errors shown in this column indicate the differences that can be expected between the estimates and comparable complete canvass totals, because of sampling fluctuations. 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..
Only selected sample error percentages are shown; standard error of the other general statistics estimates for industry groups and industries are usually of the same general magnitude as the standard errors shown for employment and value added.
The totals shown for 1947 do not include employment at central administrative offices and auxiliary units.
"The logging industry (Industry 2411) was excluded from the 1947 Census of Manufactures, but included in the Annual Survey of Manufactures. Includes privately owned and/or operated establishments classified in Industry Group 19, "Ordnance and accessories." Government owned and operated establishments are excluded from the annual survey.
"Administrative office and auxiliary unit employment is based on the number of employees reported as of Mid-March under the Old-Age and Survivors Insurance program. The 1952 figures represent administrative and auxiliary employment and payrolls for 1951, as BOASI did not tabulate these data for 1952. The approximated annual total payroll figure was derived by multiplying by 4 the first quarter taxable payroll figures listed in the joint Census-BOASI publication, County Business Patterns. The figures shown for administrative office and auxiliary units do not represent a separate industry but rather a balancing total for all manufacturing industries. The employment figures are distributed by 2-digit industry groups in the table in the introductory text.
Includes data for Sausage casings (Industry 2014).
Include data for Liquid, dried, and frozen eggs (Industry 2090) and Vinegar and cider (Industry 2096)
10The Census Bureau classification of all the textile industries is consistent with the Standard Industrial Classification (S.I.C.) system at the 4-digit level. At the 3-digit level, however, S.I.C. regroups certain of the industries according to the fibers consumed, so that the S.I.C. group 222, includes in addition to the Census Group 222, Census Industry 2212, Yarn mills, wool, except carpet; S.I.C. group 223 includes 2213, Woolen and worsted fabrics. The table below shows the 3-digit figures for 1953 and 1947 regrouped according to the 1945 edition of the Standard Industrial Classification Manual.
11Includes groups classified in 1947 as Industry 2335 "Women's suits and coats" and Industry 2336 "Women's skirts." 12 Data for 1953 and 1952 for Industry 2421 are not strictly comparable with 1947. In 1947 sawmills that produced less than 200,000 board feet of lumber were required to report only lumber production and lumber stocks; whereas in 1953 and 1952 all items covered by the survey were collected and tabulated for all establishments having 1 or more employees. It is estimated that the mills producing less than 200,000 board feet account for approximately 5 percent of total employment in Industry 2421.
13Includes data for Shingle mills (Industry 2423).
14Data for 1953 and 1952 not comparable with prior years. For 1947, establishments engaged in the production of wood or metal storm-sash, and wood-or-metal combination-screen-and-storm-sash and doors, were classified in Industry 2561, (Window and door screens). In 1953 and 1952, they are classified in Industry 2431, (Millwork plants), if the products are of wood; in Industry 3442 (Metal doors, sash and trim), if the products
are of metal.
15 Includes data for Building-paper and Building-board mills (Industry 2613).
16 Includes data for Graphite: ground and blended (Industry 3294). 17Includes data for Sand-lime products (Industry 3296).
18Includes data for Blast furnaces (former S.I.Č. Industry 3311) and Steel works and rolling mills (former S.I.C. Industry 3312). Separate figures for each industry are as follows:
19 The 1953 and 1952 data for Industries 3811 (Scientific instruments), 3821 (Mechanical measuring instruments), 3831 (Optical instruments) and 3861 (Photographic equipment) are not strictly comparable with data shown for 1947. This is due to the misclassification in 1947 of several establishments and to the change in plant definition after 1947 for some establishments. On a comparable basis in terms of value added by manufacture, it is estimated that the 1947 figures for Industry 3831 should be approximately 50 percent greater and about 5 percent less for Industry 3811.
Table 2.--VALUE ADDED BY MANUFACTURE, COST OF MATERIALS, AND VALUE OF SHIPMENTS FOR SELECTED INDUSTRIES: 1953, 1952, AND 1947 (DOLLAR FIGURES ARE IN THOUSANDS. All industries (4-digit) which are shown in the preceding table are also shown in this table. Industry group totals are not tabulated for cost of materials and value of products because of the unknown and widely varying amount of duplication contained in such totals. Such duplication arises from the use of the products of some industries as materials by other industries.)
