Title of the survey

Annual manufacturing statistics

Organization responsible

Statistics Norway

Periodicity of the survey

Annual.

Objectives of the survey

To provide detailed structural figures on employment, production and consumption for establishments in oil extraction, mining and manufacturing.

Main labour topics covered by the survey

Employment and compensation of employees.

Reference period

The calendar year.

Coverage of the survey

Geographical

The whole country.

Industrial

Oil extraction, mining, quarrying and manufacturing. The oil extraction survey is a separate survey, the results of which are combined with the annual manufacturing statistics.

Establishments

All establishments with at least half one person-year worked, excluding one-person establishments (individual proprietorships where the owner is working alone).

Persons

All persons engaged, including proprietors and owners if actively engaged in the work of the establishment, unpaid family workers and working shareholders in corporations and cooperatives. Outworkers are excluded.

Occupations

Not relevant.

Concepts and definitions

Employment

Persons engaged include all persons working in the establishment, as well as persons on sick leave, vacation and strike. Persons absent on military leave are excluded. Data are collected separately on the following: Excluded are commission agents, workers subcontracted from other companies or firms, and workers from temporary work agencies. Data are collected on the total number of employees, out of which the number of part-time workers.

Compensation of employees

This comprises wages and salaries in cash and kind, other benefits to employees and social expenses levied by law: Data on compensation of employees are compiled with respect to all employees, as defined above.

Hours of work

Data are collected on the total number of hours worked by employees.

International recommendations

The concept of compensation of employees used in the survey follows closely that recommended in the United Nations System of National Accounts (SNA) (1968 version).

Classifications

Components of labour cost / compensation of employees

Data are collected and published separately with respect to wages and salaries, other benefits to employees, and social expenses levied by law.

Industrial

Establishments or enterprises are classified according to the activity that represents the largest share in the total value added created by the establishment or enterprise. The Standard Industrial Classification (SIC) used in the survey is based on a five-digit pyramidal system in which each digit relates to a particular level of classification. The SIC corresponds closely to the International Standard Industrial Classification of all economic activities (ISIC), Rev.2, 1968. Enterprises and establishments are also classified by competitive type, in accordance with the classification used in the national accounts, i.e. sheltered groups, export-competing groups, import-competing groups.

Occupational

Not relevant.

Others

The data are classified by geographical location (County), type of ownership and sector (public and private), competitive type (e.g. export or import-competing groups), employment size and share of compensation of employees in percent of value added.

Sample size and design

Statistical unit

This is the establishment, defined as a functional unit which, at a single physical location, is engaged mainly in activities within a specific activity group. For oil extraction, the establishment is defined as a group of oil companies, which has a production licence on the Norwegian continental shelf.

Survey universe / sample frame

This consists of the Central Register of Establishments and Enterprises. The majority of entries on this register are taken from the Value Added Tax Register in the Directorate of Taxes and from the Register of Employers in the National Insurance Institution. All new employers have to register at a National Insurance Office, and all activities under the Act on value added tax must be reported to the County Tax Office for registering in the VAT register. With few exceptions, all establishments with annual sales of more than 30,000 kroner are required to be registered.

Sample design

The survey is a census of all establishments and enterprises. Only large establishments with at least 10 persons engaged on average are required to provide full data. Small establishments with less than 10 persons are only asked for data on total employment and sales, etc. In 1992, the survey covered some 11,160 establishments including oil extraction, with 291,609 persons engaged. Out of these, 4,175 establishments were large ones, with 265,153 persons engaged. Excluding oil extraction, this represents 11,137 establishments with 275,490 persons engaged, out of which 4,152 were large establishments with 249,034 persons.

Field work

Data collection

Data are collected by mail questionnaires. Data collection starts in April and continues during the summer and autumn (for large establishments).

Survey questionnaire

Complete annual reports are collected from all large establishments. For these establishments, two types of questionnaires are used. Larger establishments have to fill in very comprehensive questionnaires, while medium-size and smaller establishments receive more simple questionnaires. From small establishments, yearly reports are collected only on total employment, sales, etc. Relevant instructions are provided along with the questionnaires.

Substitution of sampling units

Not relevant.

Data processing and editing

The questionnaires are checked and the figures recorded manually, then the data are processed by computer. In case of non-responding units, missing or inconsistent data, telephone calls, reminder letters, special letters and penalties are used to collect the data.

Types of estimates

Totals of employment, employees, compensation of employees and hours worked; and average compensation of employees and hours worked per employee and per year. In estimates of employment, information is collected on the average annual number of employees by asking for figures for five points in time during the year (in February, April, June, September and November). Part-time workers are not converted to full-time equivalents.

Construction of indices

An index of industrial production is computed.

Weighting of sample results

Not relevant.

Adjustments

Non-response

In case of missing data or total non-response, the figures are imputed on the basis of information available in the register, data taken from the accounts of the enterprise, or information available from the previous year.

Other bias

None.

Use of benchmark data

None.

Use of other surveys

Not applicable.

Indicators of reliability of the estimates

Coverage of the sampling frame

This is assumed to be complete.

Sampling error / sampling variance

Not relevant.

Non-response rate

The latest non-response rate was 2 per cent in terms of establishments. It is lower in terms of employment.

Non-sampling errors

Owing to the fact that full-time and part-time workers are counted together, the figures for annual compensation of employees per employee and total employment are somewhat biased in industry groups with a large number of part-time workers.

Conformity with other sources

Not applied.

Estimates for non-survey years

Not relevant.

Available series

The following tables are published each year:

History of the survey

The survey was established in 1927 in its present form. Statistics are also available for the period before 1927 and back to the 1860s. Between 1927 and 1954, the statistics generally covered establishments with at least 12,000 hours worked (equivalent to 5 to 6 workers on average). From 1955, all establishments were included, except sole proprietorships. Furthermore, prior to 1989, establishments with sales of less than 50,000 kroner were excluded (since that date, establishments with less than half a person-year worked are excluded). For the years 1955-1960, establishments with at least six persons engaged were normally considered large, while the general limit was five persons engaged from 1961 to 1991, and 10 persons engaged since 1992. The scope of the statistics was reduced in 1970 as a consequence of changes in the Standard Industrial Classification. From that year, repair shops for motor vehicles, shoes and electronics workshops were no longer included in the manufacturing statistics, but regarded as service industries. From 1972, the group "crude petroleum and natural gas production" is included in manufacturing. That same year, a revision was also brought to the concepts of value of production, value added, compensation of employees and fixed capital formation. Since 1993, the oil extraction statistics, which come from a separate survey, are removed from the annual manufacturing statistics. Since 1993 as well, the statistics are classified according to the Standard Industrial Classification 94, the basis of which is the Statistical Classification of Economic Activities of the European Communities (NACE), Rev.1. NACE Rev.1 is itself based on the International Standard Industrial Classification of all economic activities (ISIC), Rev.3, 1990. As from 1996, the statistics will be adapted to the European Union's regulations for structural business statistics.

Documentation

Results which do not appear this publication can be made available upon request, and data can be supplied on diskette or magnetic tape.

Confidentiality / Reliability criteria

With the exception of the number of units and employment, figures for groups with less than three enterprises are not published.
