About the statistics

Definitions

Name and topic: Name: Earnings in oil and gas production and mining
Topic: Labour market and earnings

Responsible division: Division for Income and Wage Statistics

Definitions of the main concepts and variables

In the statistics, wages and salaries refer only to cash payments from employer to employee for work rendered. The statistics hence do not include payment in kind, insurance or non-taxable expense allowances and the like.

Monthly earnings

Gross monthly earnings. Includes basic salaries, variable additional allowances and bonuses. Overtime pay is not included.

Basic monthly salary

Basic monthly salary is the actual payment at the time of the census, and is often described as salary on a scale or regular basic wage. Qualification/skills allowances and other regular personal allowances are included. Wages or salaries can be paid per hour, week, fortnight or month.

Variable additional allowances

Variable additional allowances are associated with special duties, and the figure given is a calculated average per month for the period 1 January to the time of the census. Included are allowances such as shift allowance, allowances for working evenings and nights, call-out allowance, dirty conditions allowance, offshore allowance and other allowances that occur irregularly.

Bonuses

This item includes allowances usually not connected with specific duties and where the payments occur irregularly with respect to the period in which they are earned or to which they apply. Types of payments include commissions, profit sharing, production allowance and gratuities, and are a calculated average per month for the period from the 4th quarter of the previous year to the time of the census.

Overtime pay

Overtime pay covers the sum of cash compensation for work carried out beyond contractual working hours, and is a calculated average per month over the period 1 January to the time of the census.

Estimated annual earnings

Annual earnings are an estimate for 12 months of the calendar year and are based on the monthly earnings at the census time. Includes basic paid wages and salaries, variable additional allowances, bonuses, but does not include holiday pay supplement and overtime pay.

Standard classifications

Industrial classification.

A key component of the wage statistics is classification by industry in accordance with the Standard Industrial Classification (SN 2007), which is the Norwegian version of the new international Standard Industrial Classification ). More information .

Classification of occupation.

The Standard Classification of Occupation (C521), which is the Norwegian version of the International Standard Classification of Occupation (ISCO-88), is used in the statistics. This set of occupation codes is established throughout the wage statistics, either through direct input or by encoding from other occupation codes.

More information on the Standard Classification of Occupation .

Education classification.

Education levels are obtained from the register of the Population’s Highest Level of Education (BHU). The classification is by the length of education according to the Standard for Educational Classification.

Administrative information

Background

Background and purpose

The purpose of the statistics is to provide an overview of wage levels and wage changes for employees in oil and gas extraction and mining. The statistics in the current form were established in 1997.

Publications of wage statistics in 2009 apply a new Standard industrial classification (SN2007) . Wage statistics from 2008/2009 presented here are thus according to the new standard. Due to this, wage statistics from 2007 and earlier years are not directly comparable to the statistics from 2008/2009 and the years later. Closed time series from the period 1997-2007can be find using the link; Statbank .

Users and applications: Major users are the Technical Reporting Committee on the Income Settlement, research institutes, employee and employer organizations, Eurostat, the media, business and industry and private individuals. The statistics are included in Statistics Norway's National Accounts and in quarterly wage indices.

Equal treatment of users: Not relevant

Coherence with other statistics: New annual wage statistics for most industrial sections were established in 1997. The wage statistics are to be uniform and comparable among the sections . From 1st quarter 1998 a quarterly wage index has also been established including oil and gas extraction and mining.

Production

Population

The population covers all enterprises in Statistics Norway's Central Register of Establishments and Enterprises in Section B of the Standard Industrial Classification. The section is divided into monetary intermediation, insurance and other financial intermediation.

Each enterprise covers one or more establishments grouped by industrial category. The wage statistics data are obtained for each establishment at the person level.

Data sources and sampling

Data are obtained via forms or electronic media from the units covered by the sample. Information is obtained on wages, bonuses and commissions, variable additional allowances, overtime, occupation and working hours of the individual employee in the establishment.

Information from Statistics Norway's Central Register of Establishments and Enterprises and the register on the Highest Level of Education of the Population (BHU) are added to the incoming data.

The sample consists of enterprises drawn from the population. The population is basically all active enterprises in the section, with the exception of small enterprises with fewer than 5 employees, which are not included in the frame population.

The statistics are based on sampling. The final sample comprises a census part and a sample part. In the census part all enterprises with more than a certain number of employees are included, while the sample part comprises a stratified sampling of small and medium-sized enterprises. Also taken into account are the needs for the statistical basis that the parties in the wage settlement have.

The objective of the sample selection process is basically to get samples that ensure a representative basis for the statistics and avoid burdening all enterprises in the industry. Another objective is to ensure that the smallest enterprises are the least possible burdened with reporting obligations.

Collection of data, editing and estimations

The time of the census for wage statistics for employees in real estate activities is 1 September each year.

The respondent may submit the statements in electronic form, through Altinn RA-0500 The electronic reporting is described in a separate document, Requirement specification for electronic reporting , variables and file description, which is distributed to software suppliers and enterprises that organize their own payroll systems. A number of suppliers of wage administration systems have made arrangements for electronic reporting. Control and revision of wage statistics take place on several levels, where most of the operations are automated, with respect to both the actual control and any possible correction.

When receiving forms or files, a simple check is made that certain key variables are correctly filled in. This concern primarily national identity number, occupation, basic paid salaries and contractual working hours per week. The individual variables are checked in more detail in priority order in the subsequent quality control process. The highest priority is given to the variables mentioned, followed by controls of bonuses, commissions and the like, variable additional allowances and overtime.

The numerical data collected from the sample should represent the average wage level in the industry. The figures from the sample must therefore be weighted. Weighting in the statistics is based on the inverse inclusion probability and post-stratification with regard to industry and employment at the date of the census. The weights are additionally adjusted for any imbalances due to non-response. The purpose of weighting is primarily to obtain an inflation of the sample so that the units in the sample reflect the population.

Seasonal adjustment: Not relevant

Confidentiality: Not relevant

Comparability over time and space

The statistics in the current form were produced for the first time in 1997, and are comparable from that year. An overview of previous years statistics is found here .

The figures for 2005 are based on new definitions for what is required to obtain the different levels of education in Norway. The figures for wages by education are therefore not comparable from 2004 and earlier years. More information on http://www.ssb.no/english/subjects/04/01/utniv_en/ .

From 2011 the results from the survey on education completed abroad are included in the BHU. The survey resulted in a decline in the share of unknown education in the BHU from 43 per cent to 20 per cent. This affects the wage statistics from 2012. More information about the survey:

Accuracy and reliability

Sources of error and uncertainty

Measurement errors

Measurement errors can mainly occur because the respondent misunderstands what is included in and consequently reported in each column on the form or because it is very difficult for the respondent to find the information requested. All variables collected and that are directly or indirectly included in released statistics are checked, either in logical controls or by absolute limits for what is considered valid. If important data are missing in the received reports, the data are obtained either by returning the form, by a phone call to the respondent or by imputation.

Processing errors

The data that are received are registered either by optical scanning, manual recording or loading files structured according to the electronic requirement specification. Several controls are carried out on the material.

Unit non-response.

Non-response in the wage statistics is between 2.5 and 5 per cent. The main reasons for non-response are that enterprises no longer have employees because the business has been closed, sold or taken over by new owners, has gone bankrupt or has been merged in the time period between the selection of the sample and the time of the census. There is furthermore a small group that report too late to make it into the statistics. Non-responses that are not randomly distributed can still make the sample biased. Post-stratication adjusts any imbalances arising in the distribution between the stratification variables due to non-response.

Partial non-response.

Non-response in several of the items collected by form and used in the wage statistics can normally be logically calculated on the basis of other information given on the form or imputed from earlier years.

Since sampling errors are errors that may arise in areas subject to sampling, such errors are only relevant for data for "other financial mediation". In monetary intermediation and insurance all enterprises are included, so that this issue is avoided.

Variance

All sample-based surveys will be burdened with a certain uncertainty. Generally, the results are less certain the fewer the observations they are based on. Uncertainty also depends on wage dispersion and rate of coverage for the various variables in the population from which the sample is drawn. Groups that are based on relatively few observations will easily be affected by so-called extreme observations, or observations that deviate markedly from the group average. Such extreme observations are carefully considered on a case-by-case basis for inclusion in the statistical basis.

Frame errors

Incorrect industry codes and/or employment data in Statistics Norway’s Register of Establishments and Enterprises during the selection of the sample may result in the establishments being placed in the wrong industry or selection stratum.

Model errors

These are error types that include possible errors in model assumptions in the statistics.
