Occupation not reported In the separation of "Managers, officials, and proprietors (n. e. c.)" by class of worker into salaried and self-employed components, the small number of unpaid family workers in this occupation is included in the self-employed component. Mine Inborers, noted as an exclusion from the major group "Laborers, except farm and mine," are included in the major group "Operatives and kindred workers." Since the data presented in the occupation tables refer only to civilians, the category "Members of the armed forces" shown in tables 124 and 158 is limited to unemployed veterans who had not worked since their discharge from the armed forces. Relation to DOT classification.-The occupational classification of the Population Census is generally comparable with the system used in the Dictionary of Occupational Titles (DOT).10 The two systems, however, are designed to meet different needs and to be used under different circumstances. The DOT system is designed primarily for employment service needs, such as placement and counseling, and is ordinarily used to classify very detailed informaSon obtained in an interview with the worker himself. The census system on the other hand is designed for statistical purposes and is ordinarily used in the classification of limited occupational descriptions obtained in an interview with a member of the worker's family. As a result, the DOT system is much more detailed "See U. 8. Department of Labor, Bureau of Employment Security, Dictionary of than the census system; and it also calls for many types of distinctions which cannot be made from census information. Industry The industry information presented here was derived from answers to the question, "What kind of business or industry was he working in?" Classification system.-The industrial classification system developed for the 1950 Census of Population consists of 148 categories organized into 13 major groups. For the detailed industry tables in Chapter C of this volume, a few of the categories were combined, and the detailed industry list used here consists of 146 categories (tables 130, 131, and 160). The composition of each of the detailed categories is shown in the publication, U. S. Bureau of the Census, 1950 Census of Population, Classified Inder of Occupations and Industries, Washington, D. C., 1950. In Chapter B, most of the industry data are based on a condensed classification of 41 groups. In Chapter C, an intermediate classification of 77 categories has been used in the cross-classifications of industry by age, race, class of worker, major occupation group, weeks worked, and income (tables 132 to 136 and 161). Both the 41-item and 77-item classifications represent selections and combinations of the categories in the detailed system.

C. 1 Components of SIC categories 3392 and 3399 are allocated between "Other primary iron and steel industries" and "Primary nonferrous industries" on a ferrous-nonferrous basis Components of SIC categories 3463 and 3489 are allocated between "Fabricated steel products" and "Fabricated nonferrous metal products" on a ferrous-nonferrous basis. In the Population Census system, "not specified" categories were set up within certain groups to take care of schedule returns which were not sufficiently precise for allocation is a specific category within the group. Flectric light and power" and "Electric-ras utilities" are combined into a single category in the Volume II tables on detailed industry. Components of SIC categories 5099 and 5139 are allocated by type of merchandise to the appropriate Population Census wholesale trade category, wherever possible. 1 Dressmaking shops are shown separately from the rest of SIC category 7271, which is included in "Laundering, cleaning, and dyeing services." |
