2.1. Data description

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:

(a) 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

(b) 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.

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".

5.3. Completeness

Description of missing variables and missing breakdowns of the variables

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

- a detailed plan and timetable for completing implementation

- a summary of the remaining deviations from EU concepts

The optional breakdown by occupation (ISCO88/ISCO08) is not yet available.

All the information requested has been transmitted to Eurostat.

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.

Does not apply. We are using administrative registers.

Coefficient of variation (taking into account the sampling design) or estimated sampling error for the number of job vacancies (see guidelines).

Not applicable

6.3. Non-sampling error

Information on variables with non-negligible measurement and processing errors	Information on main sources of (non-negligible) measurement and processing errors and, if available, on methods applied for correction	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).

6.3.1. Coverage error

Description of any difference between the reference population and the study population	Description of classification errors	Description of any difference between the reference dates and the reference quarter	Any other relevant information
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.	Not available	Not applicable

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 46% 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):

The comparison of employees and occupied posts is hampered by the large amount of cross-border workers in Luxembourg. The LFS data takes into account only the employment of residents. The JVS data stems from social security and thus takes into account all the occupied posts in Luxembourg, be it by residents or commuters. This explains the large differences in all sectors.
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).
