Comparability

Comparability - geographical

So far as it is known, no other countries have developed a similar workplace statistic.

Comparability over time

The EiB statistic have been compiled since the reference year 1990.

It replaced the register-based workplace statistics, which had been compiled for the reference years 1980-1989, and which covered only establishments with employees. The methodology had remained largely unchanged from 1980 to 1989, so for that period comparability is good.

The introduction of the EiB statistic completed the coverage by adding information about self-employed and working spouses. Thus, establishments without employees also became part of the register basis from the reference year 1990. Furthermore, information about socio-economic status was included in the EiB. However, this improved coverage cannot be added to the data before 1990.

In 1993, the DB93 replaced the DSE77 as the official Danish classification of activities, and a break in the time series occurred. DB93 is fully implemented in the EiB statistic 1994.

From 2002 the EiB include only establishments connected with enterprises, which have a certain activity.

In 2003 the classification of activities changes to DB03 and in 2008 the classification of activities changed to DB07.

From 2005 also secondary jobs as self-employed is included in the EiB.

In 2008 the e-income register became the main data source to the EiB. The transition to the e-income register as the new data source means that there is a data break in the EiB from 2007 to 2008. The number of jobs at the end of November declined by around 71,000 as a result of the transition.

From 2008 all active jobs at the end of November are included. Earlier only the primary and secondary job was counted. At the same time jobs where the person is on maternity or sicknes leave were excluded. Before 2008 only jobs where the person was on labour market leave were excluded.

With the publication of the EiB for 2013 at the end of May 2015 the AMR-UN (labour market account without hour standardization) is used as data basis. AMR-UN is made in the production of the labour market account and or among other things based on the e-income register. You can read more about the labour market account and AMR-UN here.

At the same time changes in the calculation of full-time employment is made, which means that job at the end of November, where the employee is temporarily absence, isn't included in the calculation of full-time employment. So far, wage hours over 1924 hours (equivalent to a weekly employment of 37 hours) are not counted in the full-time employment. With the publication of the EiB for 2013 these hours will be included in the calculation of full-time employment. All in all, will these changes reduce the level of full-time employment. Furthermore, the calculation of job now includes all job in Denmark regardless the persons are resident in Denmark or not.

The transition to AMR-UN and the changed calculation of full-time employment and number of jobs give a data break in the statistic. Therefore, new tables (ERHV1 to ERHV5) in Statbank Denmark is made covering the period 2008 to 2013. During this period the figures are thus comparable.

Coherence - cross domain

The EiB is based on the same data material as the register-based labour force statistic (RAS). However, some major conceptual differences should be noted.

RAS calculates only the primary employment, whereas EiB also includes information about other employee jobs.

Persons, who according to the work classification modul (AKM) have their primary income in the year as self-employed, are only included in RAS.

Also persons on leave from employment at the end of November are included in RAS, but not in EiB.

Furthermore job on establishments connected to enterprises with low activity are included in RAS, but not in EiB

Coherence - internal

There is full consistency. All establishments contain the same types of basic information.
