National reference metadata

Norway

Reference metadata describe statistical concepts and methodologies used for the collection and generation of data. They provide information on data quality and, since they are strongly content-oriented, assist users in interpreting the data. Reference metadata, unlike structural metadata, can be decoupled from the data.

This report covers all the main points related to quality that normally are covered and commented on in connection with the publication of statistics, and in this case statistics on earnings. The aim is to supply information on the quality of the data and statistics from Statistics Norway that are reported to and distributed by Eurostat in connection with the Structure of Earnings Survey 2018.

Statistics Norway base its statistics on earnings on the reporting through a-ordningen which was put into effect in 2015 in collaboration with Norwegian Tax Authority and the Norwegian Labour and Welfare Administration. The system for collecting and regulating procedures are covered by legislation under the A-opplysnings act.

Statistics Norway receives monthly registry data concerning jobs, remunerations, and taxes (including payroll taxes) through a-ordningen. This is a mandatory electronic reporting system for anyone who has employees or who pays salary, pension, or other benefits.

A-ordningen was established in 2015 and is a collaborative system between Statistics Norway, the Norwegian Tax Authority and the Norwegian Labour and Welfare Administration. A-ordningen provides a digital service, where the information is submitted electronically every month via the employer’s payroll system to the Tax Administration, which administers a-ordningen.

Anyone who has employees or who pays salary, pension or other benefits, such as social security, must submit an electronic form called an a-melding. This is regulated by law (A-opplysnings act) with a lower threshold amount of NOK 1 000 per year[1]. The a-melding does not cover self-employed.

In summary, A-ordningen is a collaborative system, while the A-melding is an electronic form submitted to this system. Every year, approximately 250 000 employers (per month about 190 000) submit information concerning 4.8 million employees and pensioners via the a-ordning. E.g. type of employment, start and end data for the job, contractual full-time equivalent (FTE) percentage, salary and remuneration in cash and kind, and pension. Employers are also required to report information about some deductions, employer’s national insurance contribution and financial activity tax. More information about a-ordningen is available at the Norwegian Tax Authority’s website (Skatteetaten.no).

 

Differences between Norwegian Wage Statistics and SES2018:

Job/Employee (employment/individual)

The analysis unit in the national statistics is job per employee per local unit of activity. An employee (individual) can have more than one job within an enterprise but is only allocated max one job per local unit of activity. Therefore jobs (employments) within the same local unit are aggregated into one. The number of jobs in the national statics will therefore exceed the number of employees (individuals).

In accordance with the regulations for SES Statistics Norway has selected the main job per employee (individual), as the base unit for compiling data for the SES2018. Most differences in comparison between Statistics Norway’s statistics on earning and statistics disseminated by Eurostat can be attributed to this difference. Statistics Norway also include industries Agriculture, forestry and fishing (NACE section A), Activities of households as employers (NACE section T) and Activities of extraterritorial organizations or bodies (NACE section U). Of the mentioned industries covered by Statistics Norway’s earnings statistics section A Agriculture, forestry and fishing constitutes the most significant contribution in difference between National earnings statistics and the SES 2018.

The population is defined as follows:

  1. Employees working in the reference week in the reference month (the reference week is established as the middle week that also includes the 16th day of the month)
  2. In addition, the employed must have received a fixed salary or hourly wage during the reference month

Mean annual gross earnings gives the actual gross earnings in the year 2018, as the accumulated remuneration in cash for all the months in the year. 

Mean monthly gross earnings in the reference month covers gross remuneration in cash before any tax deduction and social security contributions payable by wage earners and retained by the employer.

Mean hourly gross earnings are defined as gross earnings in the reference month divided by the number of hours paid during the same period.

Number of hours paid includes all the estimated normal and overtime hours worked and remunerated by the employer during the reference month.

Employees, local units and enterprises.

The population covered in SES2018 are all employees who received remuneration in cash for the reference month (September), as requested by the Regulation, in the enterprises and institutions belonging to the Private and Public sectors in the NACE Rev. 2 sections B to S and regardless size (number of employees).

As explained in point 2.1, only information on employee’s main job has been used in SES.

Norway.

Not Applicable

The accuracy and reliability of the statistics is not affected by sampling errors or other biases connected with surveys since data collected represent a full coverage of all enterprises regardless of size, sector and economic activity (B-S).

Not Applicable

As explained in the  preceding paragraphs, information on employee’s main job only has been included in the compilation of the datasets for the SES 2018.

Every single employee who received remuneration for the reference month (September) in the enterprises and institutions belonging to the Private and Public sectors in the NACE Rev. 2 sections B to S are included in the SES2018 population. The only exceptions are a few observations with an error in age that were removed from the original dataset.

As of the year 2015 the Norwegian wage statistics are based on a full census from the establishment of a-ordningen.

A-ordningen is a coordinated reporting of wage and employment information to the Tax Administration, Norwegian Labour and Welfare Administration (NAV) and Statistics Norway.

Data is reported directly from the employers to the Tax Administration, via digital seamless, 24/7 open channels.

All employers who have paid wages, cash benefits or any other benefits must submit data each month, within the 5th of the following month. The data thus covers all employees in all enterprises, therefore the Norwegian earnings statistics cover the whole population as defined by the current regulations. The aforementioned reporting also represents the main source for much of statistics Norway’s labor market statistics or constitutes a substantial part of the frame work or calculations.

The reference period for this survey is September 2018, the same as for the national earnings statistics.

The national earnings statistics for 2018 were published on 04/02/2019. The gap between the end of the reference year and the date of publication is thus approximately 35 days, from the reference month the difference is 4 months.

The SES data appeared for the first time on Eurostat database in October 2020, gap of about 20 months from the reference year.

Norway only constitutes one region in the European SES. National statistics on earnings are divided by regions and comparisons can be made.

The Norwegian earnings statistics are collected annually and comply with most mandatory points drawn up in the council regulation 530/1999, and subsidiary commission regulations.

Statistics Norway has carried out the SES five times; for the reference years of 2002, 2006, 2010, 2014 and 2018.

SES 2018 has been compiled using census data from a-ordningen, whilst sample surveys were conducted for all years before 2015. Data utilized for SES 2018 are more complete and differences with earlier years derive from survey sampling errors and sample design.

Comparisons between the years can be done but caution is advised, consult documentation for all comparisons with data from before 2015.

Since SES 2010 ISCO-08 is used for classifying occupations. 

Since SES 2014 the International Standard Classification of Education, 2011 version is used for classifying education.

Comparable national annual statistics on earnings were established for most industrial sections in 1997, a few sections were included later. The statistics are comparable from 1997 and are uniform and comparable among the sections. There has not been any change in the definitions of variables since 1997. The applied methods and models have however been subject to ongoing improvement based on increased knowledge and new requirements since they were established. These ongoing improvements have not affected comparability.
