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.
Job vacancy statistics (JVS) provide information on the level and structure of labour demand. The country transmits to Eurostat the quarterly data on the number of job vacancies and the number of occupied posts as well as provides the quality report under the existing regulations.
2.2. Classification system
The quarterly data are broken down by economic activity (at section level) in accordance with NACE Rev. 2 - Statistical classification of economic activities in the European Community.
2.3. Coverage - sector
The data cover all the economic activities defined by NACE Rev. 2, except the activities of households as employers and the activities of extraterritorial organisations and bodies.
2.4. Statistical concepts and definitions
A 'job vacancy' is defined as a paid post that is newly created, unoccupied, or about to become vacant:
for which the employer is taking active steps and is prepared to take further steps to find a suitable candidate from outside the enterprise concerned; and
which the employer intends to fill either immediately or within a specific period of time.
‘Active steps to find a suitable candidate’ include:
notifying the job vacancy to the public employment services,
contacting a private employment agency/head hunters,
advertising the vacancy in the media (for example internet, newspapers, magazines),
advertising the vacancy on a public notice board,
approaching, interviewing or selecting possible candidates/potential recruits directly,
approaching employees and/or personal contacts,
using internships.
'Specific period of time’ refers to the maximum time the vacancy is open and intended to be filled. That period shall be unlimited; all vacancies for which active steps are continuing on the reference date shall be reported.
An 'occupied post’ means a paid post within the organisation to which an employee has been assigned.
2.5. Statistical unit

Description of the national users and their main needs
Remarks
STATEC's "economic analysis unit" uses JVS data to compare Luxembourg's vacancy rates to those observed in other countries. The unit needs the results timely. Moreover, the breakdown by activities is important for STATEC's "economic analysis unit".

Report progress on the implementation measures regarding quarterly job vacancies statistics of Regulation (EC) No 453/2008, including :

The optional breakdown by occupation (ISCO88/ISCO08) is not yet available.
All the information requested has been transmitted to Eurostat.
5.3.1. Data completeness - rate

6.1. Accuracy - overall
The job vacancy statistics in Luxembourg are entirely compiled via administrative records. Hence, a lot of the concepts from this section do not apply.

Estimation bias: An assessment of the non-sampling errors, in terms of the absolute number of vacant posts, for the total number of job vacancies and, where possible, for aggregation level of NACE Rev. 2 specified in Annex 1 to this Regulation and size classes (1-9, 10 + employees).

Some firms (legal units) have to be excluded due to the fact that no NACE code could be attributed to them. Indeed, if job vacancies are posted by newly founded firms it can happen that these firms have not yet been assigned a NACE code.

For the Beveridge Curve and a comparison of employees between LFS and JVS, please refer to the annexes at the end of this Quality Report.
Comments :
1. Regarding the Beveridge Curve:
The calculations of the vacancy rate (VR) and the unmployment rate (UR) are not coherent. The VR uses domestic employment as denominator whereas the UR uses national employment. The difference between these two is huge in Luxembourg: some 47% of the domestic workforce does not reside in Luxembourg. Moreover, national and domestic employment do not have the same evolution over time.
The Beveridge Curve is drawn with quarterly data. The quarterly unemployment rate from the LFS is pretty volatile as it is calculated on very small samples.
2. Regarding the comparison of employees (LFS) and occupied posts (JVS):
Sector P is a special case as the social security data used for JVS includes public education into section O instead of P, as persons working in public schools are on the government's payroll. However, in the LFS, the activities are self-declared. Here people working in public education tend to declare that they work in the educational sector and are hence registered in section P. If in both sources, O and P are combined, the remaining difference is small and stems from the previously mentionned point (commuters).
