BUSINESS UNITS UNDER SOCIAL SECURITY, FIRST QUARTER, 1959

Items 83-85. Employers and employment covered by Social Security.

Source: Bureau of the Census and Bureau of Old-Age and Survivors Insurance, cooperative report, County Business Patterns, First Quarter 1959, Part I, U.S. Summary.

These figures are derived from administrative reports for old-age, survivors, and disability insurance (OASDI) coordinated with reports of the Censuses of Business, Manufactures. and Mineral Industries, and a special survey of multiunit companies conducted by the Census Bureau.

The data comprise (a) all OASDI-covered wage and salary employment of nonfarm industrial and commercial employers and nonprofit membership organizations (operated for the promotion of the interests of their members) and (b) all employment of religious, charitable, educational, and other nonprofit organizations voluntarily covered under the elective provisions of the Federal Insurance Contributions Act. The figures exclude: Farm workers, domestic workers, members of the Armed Forces, all Federal civilian employees not covered and most of those covered under a Federal retirement system, employees of State and local governments, railroad employment subject to Railroad Retirement Act, employees on oceanborne vessels, and selfemployed persons.

Since the county coding system used by the Bureau of Old-Age and Survivors Insurance for tabulating data provides for a maximum of 99 counties in any one State, combinations of figures for two or more contiguous counties were required in the following States: Georgia, Illinois, Kansas, Kentucky, Missouri, North Carolina, Texas, and Virginia. The five boroughs of New York City are combined into one group. The independent cities of Baltimore, Md., and St. Louis, Mo., are treated as separate counties. In Virginia, independent cities, except Hampton and Newport News, are combined with the counties from which they originated. Los Alamos and Sandoval Counties in New Mexico are combined into 1 group.

The sum of the county figures for a particular State usually does not equal the State total shown because "Statewide" reporting units are included in the State totals. "Statewide" reporting units are those without a fixed location within the State, or with a significant number of employees in more than one county, or of unknown county locations. This incomplete county detail causes only slight understatement of county employment.

A reporting unit is, generally, a single establishment or a group of similar establishments operated by one employer. Nonmanufacturing establishments of an employer are grouped into a single reporting unit if they are in the same county and engaged in the same kind of business. For manufacturing industries, reporting establishments represent single establishments.

Figures for Item 84 represent the number of employees during the pay period ending nearest March 15, 1959. These figures were obtained from the employer's tax return and, in those cases where they were incompletely or improperly reported, are corrected by estimates.

Figures for taxable payrolls, January-March, represent the amount of taxable wages paid for "covered employment" during the quarter. Under the law in effect in 1959, taxable wages for covered employment were all payments up to the first $4,800 paid to any one employee by any one employer during the year, including the cash value of payments in kind. In general, all payments for covered employment in the first quarter were taxable unless the employee was paid at the rate of more than $19,200 per

year.

MANUFACTURES, 1958

Items 86-95. General note.

The 1958 Census of Manufactures covers all establishments primarily engaged in manufacturing, as defined in the 1957 edition of the Standard Industrial Classification Manual. The NIC Manual defines manufacturing as the mechanical or chemical transformation of inorganic or organic substances into new products. The assembly of component parts of products is also considered to be manufacturing, if the resulting product is neither a structure nor other fixed improvement. These activities are usually carried on in plants, factories, or mills, which characteristically use power-driven machines and materials-handling equipment.

The 1957 edition of the SIC Manual represents a major change from the 1945 edition which was used for the 1954 Census of Manufactures. Among these changes are:

a. Addition to the manufactures group of approximately 3,500 establishments primarily engaged in producing readymixed concrete (Industry Number 3273 as classified in the 1957 SIC) which employed approximately 59,000 employees and were formerly classified in the wholesale and retail trade groups; and an intermediate large number of machine shops solely engaged in repair work, formerly classified with service trades group, and merged with “machinery and parts, except electrical, not elsewhere classified" (Industry Number 3599).

b. Transfer from the manufactures group to the service trades group of establishments primarily engaged in retreading or rebuilding tires. Neither the number of establishments nor the number of employees affected by this change are presently known.

For additional information on changes in scope and classification of certain industries within the manufactures group, see Bureau of the Census, U.S. Census of Manufactures: 1958, Vol. II, Industry Statistics, Parts 1 and 2.

The Census of Manufactures is conducted on an establishment basis. Thus, a company operating establishments at more than one location is required to submit a report for each location. In addition, companies engaged in distinctly different lines of activity at one location are required to submit separate reports, provided the plant records permit such a separation and provided the activities are substantial in size. Census tabulations of establishment reports, therefore, differ from tabulations prepared on a company basis, i.e., from consolidated reports which combine activities at different locations. Reports were required from all establishments employing one or more persons at any time during 1958. Figures exclude statistics for separate central administrative offices and auxiliary units of multiestablishment companies.

Items 86-88. Manufacturing establishments, by employment sizeclass.

Source: Bureau of the Census, U.S. Census of Manufactures: 1958, Vol. III, Area Statistics.

A manufacturing establishment is generally defined as a single physical location where industrial operations are performed; e.g., a factory, mill, or plant. An establishment is not necessarily identical with the business concern or firm, which may consist of one or more establishments. It is also to be distinguished from organizational subunits, departments, or divisions within an establishment.

The minimum size for including establishments is limited to establishments employing one or more persons at any time during the census year. This limitation has applied since 1947. See general note for Items 86-95.

Items 89-90. All employees, number and payroll.

Source: Same as Items 86-88.

Figures comprise all full-time and part-time employees on the payrolls of operating manufacturing establishments who worked or received pay for any part of the pay period ending nearest the 15th of 4 specified months (see below). Included are all persons on paid sick leave, paid holidays, and paid vacation during these pay periods. Excluded are members of the Armed Forces and pensioners on the active rolls but not working during the period. Officers of corporations are included as employees; proprietors and partners of unincorporated firms are excluded.

Employee figures were reported separately for "production and related workers" and for "all other employees." Figures

for the former were for midmonth employment in March, May, August, and November; for "all other employees," only for midMarch employment. Thus, the figures for Item 89 are an average of the 4 monthly figures for "production workers" plus the March figure for "all other employees."

Payroll includes the gross earnings paid in 1958 to all employees of operating manufacturing establishments. Included are all forms of compensation, such as salaries, wages, commissions, dismissal pay, bonuses, vacation and sick leave pay, and compensation in kind, prior to such deductions as employees' social security contributions, withholding taxes, group insurance, union dues, and savings bonds. Payroll also includes salaries of officers of an incorporated establishment. Excluded are payments on drawing accounts of proprietors or partners, payments to members of Armed Forces and pensioners on the active payroll, and employers' social security contributions or other nonpayroll labor costs.

Employment and payroll figures do not include central administrative offices and auxiliaries.

See general note for Items 86-95.

Items 91-93. Production workers, number, man-hours, and wages. Source: Same as Items 86-88.

The number of production workers includes all production and related workers (up through the working foreman level) engaged in fabricating, processing, assembling, inspection, receiving, storage, handling, packing, warehousing, shipping (but not delivering), maintenance, repair, and janitorial and watchman services; product development; auxiliary production for plants' own use (e.g., power plant); recordkeeping; and other services closely associated with production operations at the establishment covered by the report. Supervisory employees above the working foreman level are excluded.

Man-hours consist of all plant man-hours worked by production and related workers, including actual overtime hours. They exclude time spent on vacations, holidays, and sick leave whether or not an employee received pay for these periods. If an employee elected to work during his vacation period, only the hours actually worked were counted.

Wages represent all compensation paid to production workers. See general note for items 86-95.

Item 94. Value added by manufacture, adjusted.

Source: Same as Items 86-88.

Unadjusted figures were first obtained by subtracting the cost of materials, supplies and containers, fuel, purchased electric energy, and contract work from the value of shipments (net selling values, f.o.b., plant) for products manufactured plus receipts for services rendered.

The resulting figures for 1958 were then adjusted by the addition of the following: (a) The difference between the sales price and cost of merchandise sold without further manufacture, processing, or assembly, and (b) the net change in finished products and work-in-process inventories between the beginning and the end of the year. In 1954, the value-added figures (Item 97) were not adjusted for these two aspects and are, therefore, referred to as "unadjusted."

See general note for Items 86-95.

Item 95. Capital expenditures, new.

Figures represent expenditures made during 1958 for permanent additions and major alterations to manufacturers' plants, as well as for new machinery and equipment purchases that were chargeable to fixed-asset accounts and were of a type for which depreciation accounts are ordinarily maintained. Expenditures for machinery and equipment include those made for replacement purposes, as well as for additions to plant capacity. Excluded are costs of maintenance and repairs charged as current operating expense, expenditures for land, and expenditures made by owners of plants and equipment leased to reporting manufacturers. See general note for Items 86-95. MANUFACTURES, 1954

Items 96-97. All employees and value added by manufacture, unadjusted.

For definition of concepts, see text for Items 86-88 and Item 94. See also general note for Items 86-95.

The county figures for some States do not add to the State totals shown. This apparent discrepancy is due partly to rounding and partly to the revision in 1958 of the 1954 State totals without corresponding changes in county figures, or to revision of county figures without corresponding changes in State totals. All such revisions were minor.

RETAIL TRADE, 1958

Items 98-110. General note.

Retail trade, as defined in the Standard Industrial Classification Manual (see references under general note, Items 86-95) and as covered in the 1958 Census of Business, includes establishments primarily engaged in selling merchandise to personal, household, and farm users. Retail liquor stores operated by State and local governments are also included although they are not classified as retail trade in the SIC Manual. The figures shown here exclude data on administrative offices, warehouses, and other auxiliary units which service retail establishments of the same organizations.

For the most part, establishments engaged in retail trade sell merchandise to the general public for personal or household consumption. Certain exceptions to this general rule are made necessary by trade practices. For example, retail lumber yards are included in retail trade despite the fact that a high proportion of their sales are made to contractors. Excluded from retail trade are places of business operated by institutions and open only to their own members or personnel, such as restaurants and bars operated by clubs, school cafeterias, and eating places operated by industrial and commercial enterprises for their own employees.

For purposes of coverage in the 1958 Census, retail establishments were divided into two categories: Those with some paid employment during 1958, and those with no paid employment. Information for establishments having paid employees was ob

tained by a mail canvass. Information for establishments with no paid employment was derived from 1958 Federal income tax returns. Establishments with no paid employment and a sales volume of less than $2,500 in 1958 were excluded.

Establishments covered by the census were assigned a kind-ofbusiness classification in accordance with the provisions of the 1957 edition of the SIC Manual.

In all major respects, the 1954 and 1958 Censuses were conducted under similar conditions and procedures. However, strict comparability is affected by the combining in the 1958 Census of "leased departments" with the retail business in which located. Leased departments are businesses operated as departments of a retail business and not owned by the principal owner of the business establishment in which they are located. In 1954, these departments were counted as separate establishments.

For a discussion of other factors which affect strict comparability, see source publication.

Items 98-99. Retail establishments.

Source: Bureau of the Census, U.S. Census of Business: 1958, Vol. II, Retail Trade, Area Statistics.

The number of establishments represents a summary of reports for individual "establishments" rather than "companies." A separate report was obtained for each location where business was conducted, including each location of multiunit organizations. Each report was tabulated in accordance with the physical location at which the business was conducted.

Where two or more activities were carried on at a single location under a single ownership, all activities were generally grouped together as a single establishment; the entire establishment was then classified on the basis of its major activity, with all data for it included in that classification. However, in cases where distinct and separate economic activities were conducted under the same ownership at a single location, and where conditions prescribed by the SIC Manual for recognizing the existence of more than one establishment were met, separate establishment reports were made for each of the different activities.

The number of establishments shown here is the number in business as of December 31, 1958.

See general note for Items 98-110.

Items 100-101. Sales of retail establishments.

Source: Same as Items 98-99.

Sales are defined to include the total of merchandise sold plus receipts from repairs and from other services to customers, whether or not payment was received in 1958. Sales are normally recorded net of deductions for refunds and allowances for merchandise returned by customers. Total sales exclude amounts other than those received from customers, such as income from investments, rental of real estate, etc. They include the amount of local and State sales taxes and Federal excise taxes collected by the store directly from customers and paid directly by the store to a local, State, or Federal taxing agency.

The sales figures represent total sales and receipts of all establishments primarily engaged in retail trade. They exclude retail sales made by manufacturers, wholesalers, service establishments, and other businesses whose primary activity is other than retail trade. They do, however, include receipts other than from the sale of merchandise at retail (e.g., service receipts, sales to industrial users, sales to other retailers, etc.).

Although the figures shown here for number of retail establishments represent the number in business at the end of the year,

the sales figures include sales of all establishments in business at any time during the year.

See general note for Items 98-110.

Items 102-104. Retail trade payroll, paid employees, and active proprietors.

Source: Same as Items 98-99.

Payroll comprises all forms of compensation (salaries, wages, commissions, bonuses, and payments in kind) paid during the year to all employees. It includes amounts paid to officers and executives of corporations; it does not include compensation of proprietors or of partners of unincorporated businesses. Included in payroll are the value of payments in kind, such as free meals, lodgings, etc., but not amounts received by employees as tips, etc. Payroll is reported before deductions for social security, income tax, insurance dues, etc.

Paid employees consist of the number of employees, including salaried officers and executives of corporations, who were on the payroll during the workweek ending nearest November 15, 1958.

Active proprietors of unincorporated businesses comprise owners or partners who devoted the major portion of their time to the operation of the business.

See general note for Items 98-110.
Items 105-106. General merchandise group.

Source: Same as for Items 98-99.

This group includes stores usually selling a combination of two or more of the following kinds of merchandise: Dry goods, apparel and accessories, furniture and home furnishings, small wares, hardware, and food. Among the kinds of business included in this group are those commonly known as department stores, limited price variety stores (5-and-10, etc.), dry goods stores, sewing and needlework stores, and general stores. See general note for Items 98-110 and text for Items 98-99 and 100-101.

Items 107-108. Food stores.

Source: Same as for Items 98-99.

This group comprises establishments primarily selling food for home preparation and consumption. Establishments primarily selling prepared foods and drinks for consumption on their own premises are classified as “eating and drinking places," and stores primarily engaged in selling packaged beers and liquors are classified separately as "liquor stores." Among the kinds of business included in this group are grocery stores, meat markets, fish markets, fruit stores and vegetable markets, candy stores, dairy products stores, retail bakeries, and egg and poultry dealers.

WHOLESALE TRADE, 1958

Items 113-118. General note.

Wholesale trade, as defined in the 1957 edition of the Standard Industrial Classification Manual (see reference under general note, Items 86-95) and as covered in the 1958 Census of Business, includes establishments with one or more paid employees and primarily engaged in selling merchandise to retailers; to institutional, industrial, commercial, and professional users; or to other wholesalers; or in negotiating as agents in buying merchandise for, or selling merchandise to, such persons or companies. Importers selling merchandise at wholesale in the U.S. market, exporters, and wholesale liquor establishments operated by State governments are included. Statistics shown here exclude data for administrative offices, warehouses, and other auxiliary units which service wholesale establishments of the same organizations.

In all major respects, the 1954 and 1958 Censuses were conducted under similar conditions and procedures. For a discussion of several factors which affect strict comparability, see source publication.

The 1958 Census of Business covered all establishments primarily engaged in selected service trades as defined in the 1957 edition of the Standard Industrial Classification Manual (see reference under general note, Items 86-95). The Service Division is defined to include establishments primarily rendering a wide variety of services to individuals and businesses. The SIC Manual includes 14 major groups in the Service Division of which 7 are included in the census, essentially in their entirety, as follows:

70. Hotels, roominghouses, camps, and other lodging places. The subordinate groups, "rooming and boarding houses" and "organization hotels and lodginghouses, on membership basis,” are excluded.

72. Personal services.

73. Miscellaneous business services.

75. Automobile repair, automobile services, and garages. 76. Miscellaneous repair services.

78. Motion pictures.

79. Amusement and recreation services, except motion pictures. Symphony orchestras, ballet and opera companies, and similar services organized on a nonprofit basis are included. Establishments in Group 79 which are operated to provide recreational facilities for their own members and which are exempt from payment of Federal income tax under the provisions of Sec. 501 of the Internal Revenue Code are not included. Excluded from coverage in the census are medical and other health services; legal services; education services; museums, art galleries, and botanical and zoological gardens; nonprofit membership organizations; private households; and miscellaneous services.

The figures shown here exclude data on administrative offices, warehouses, and other auxiliary units which service establishments of the same organization.

In all major respects, the 1954 and 1958 Censuses were conducted under similar conditions and procedures. For a discussion of several factors which affect strict comparability, see source publication.

MINERAL INDUSTRIES, 1958

Items 129-132. General note.

The 1958 Census of Mineral Industries covers all establishments primarily engaged in mining as defined in the 1957 edition of the Standard Industrial Classification Manual (see reference under general note, Items 86-95). The SIC Manual defines mining in the broad sense to include the extraction of minerals occurring naturally: Solids, such as coal and ores; liquids, such as crude petroleum; and gases, such as natural gas. Mining also includes quarrying, well operation, milling (crushing, screening, washing, flotation, etc.), and other preparation needed to render the material marketable, as well as exploration and development of mineral properties.

The crushing, grinding, or other treatment of certain earths, rocks, and other nonmetallic minerals not in conjunction with mining activities are excluded. Hauling and other transportation beyond the mine property and contract hauling (except out of open-pits in conjunction with mining) are also excluded.

Statistics on mining operations carried on as secondary activities at manufacturing establishments (such as clay pits at clay products plants or sand and gravel operations at readymixed concrete plants) are, insofar as possible, excluded from the figures shown.

The Census of Mineral Industries is conducted on an establishment basis. That is, a company carrying on mining or mineral preparation activities at more than one location is required, in general, to submit a report for each location; also, companies engaged in both mining and manufacturing activities at one location are required, in general, to submit separate reports.

A mineral establishment is generally defined as a single physical location where mineral operations are conducted; for example, a mine only, a mine and preparation plant, or a preparation plant only.

The minimum size for including establishments was limited to those employing one or more persons at any time during 1958 and for establishments with no employees, those with the value of shipments or reported expenditures amount to $500 or more. The same size limitations were applied in 1954.

The production of minerals, particularly stone, sand, and gravel, by Federal, State, and local governments is excluded. Also excluded is some production of these items by highway contractors who do not maintain separate records for sand and gravel production. Included are mining establishments operated entirely to serve other establishments of the same company, such

as coal mines serving only coke ovens operated by the same company, oil and gas wells serving only refineries or public utilities owned by the same company, and copper mines and mills where all of the ore is transferred to a company-owned smelter.

State totals shown for establishments, employment, and payrolls are not necessarily the sum of the figures shown for counties. Discrepancies are due to the allocating procedures used to obtain county and State figures for companies operating oil and gas field properties and companies performing certain mining service operations. Only one report was required for all oil and gas field operations of a company in each State.

Items 129-131. Mining establishments, employees, and payroll. Source: Bureau of the Census, U.S. Census of Mineral Industries: 1958, Vol. II, Area Statistics.

For definition of establishments, see general note for Items 129-132.

Employee figures include all full-time and part-time employees on the payrolls of the operators of mining establishments and mining contractor establishments who worked or received pay for any part of the pay period ended nearest the 15th of 4 specified months (see below). All persons on paid sick leave, paid holidays, and paid vacations during these pay periods are counted. Also included are employees of miners paid on a per ton, car, or yard basis. Excluded are: (a) Employees at the mine who were on the payroll of another employer (but employees of mining contractors are included in the reports for such contractors); (b) employees at company stores, boardinghouses, bunkhouses, and recreational centers; (c) members of the Armed Forces and pensioners on the active rolls but not working during the period. Officers of corporations are included as employees; proprietors and partners of unincorporated firms are excluded.

Employee figures were reported separately for "production and development workers" and for "all other employees." Figures for the former were for midmonth employment in March, May. August, and November; for the latter, only for mid-March employment. Thus, the figures for Item 130 are an average of the 4 monthly figures for the former group plus the March figure for the latter.

Payroll figures include the gross earnings paid in 1958 to all employees on the payroll of operating mining establishments. Included are salaries, wages, commissions, dismissal pay, bonuses, vacation and sick leave pay, and compensation in kind prior to such deductions as employees' social security contributions, withholding taxes, group insurance, union dues, and savings bonds. Excluded are payments to members of the Armed Forces and pensioners on the active payroll of mining establishments, royalty payments to unions, and costs of smithing, explosives, fuses, electric cap lamps, and mine supplies used in production and development work but charged to employees and deducted from their wages.

Item 132. Value of shipments and receipts.
Source: Same as Items 129-131.

Value of shipments is the net selling value, f.o.b., mine or plant, after discounts and allowances, and excluding freight charges.

"Shipments" include all products physically shipped from an establishment during 1958, including material withdrawn from stockpiles and products shipped on consignment, whether or not sold in 1958. Products transferred to other establishments of the same company or prepared on a custom basis are reported at approximate commercial value, not at the cost of production, The figures include (a) the value of all primary products and of secondary products which are primary to other industries; (b) the receipts for contract work done for others (except custom
