Enquête Mobilité résidentielle hors des frontières luxembourgeoises (EVALUX)
Survey of residential mobility outside the Luxemburg borders (EVALUX)
This was a survey conducted by post in spring 2008, by the LISER (formerly CEPS/INSTEAD) in partnership with the Europa Forum. The field of study comprised all employed members of the working population who were Luxembourg residents but had gone to live in a neighbouring country between 2001 and 2007, while continuing to work in the Grand Duchy. Four selection criteria were used, i.e. people who had:
(i) moved from Luxembourg to a German, Belgian or French area of the Greater Region,
(ii) moved between 2001 and 2007,
(iii) been employed in the Grand Duchy both before and after the move,
(iv) lived in the host country for at least six months.
These criteria eventually resulted in the selection of a parent population of 7,715 people. Overall, the average age and therefore the average income were slightly lower than those of Luxembourg's resident working population, although this does not mean that the phenomenon can be described as residential relegation (Carpentier, 2010).
To analyse the reference population and establish a contact base, both of which were essential in order to ensure that the survey was conducted properly, data was used from the files of Luxembourg's Social Security Authority (Inspection Générale de la Sécurité Sociale/IGSS). This longitudinal administrative data base contains data on everyone covered by Luxembourg's social security scheme, and is the only one to contain, with a certain level of temporal depth, both residents of Luxembourg and cross-border workers from Germany, Belgium and France. As the data base contains individual information only, questions about families and any changes developing in them (separation, setting up home together, births, etc.) when the move took place, were added to the questionnaire.
Of the 7,715 people contacted, the response rate of 25% resulted in a final sample comprising 1,939 respondents, for whom, in addition to the usual sociodemographic data, there was data concerning their various addresses, as well as a certain number of places where everyday activities were carried out, both before and after moving away from Luxembourg. Specifically, ten types of activity were addressed: place of work, spouse's place of work, food shopping, doctor's appointments, sports activities, visits to friends, visits to members of the family, hairdressing appointments, restaurants and cinema trips. For each type of everyday activity, respondents were asked to choose the place where the said activity most often took place. In order to reduce the amount of time taken to complete the questionnaire, which, let us not forget, was self-administered, no questions were asked about, for example, the route taken, times, frequency, and transport links. Thus the aim was not to collect information on a typical day's travel, but to specify, based on their habitual activities, the places where these new « suburban cross-border workers » conducted their everyday lives (and the journeys that this involved).
LISER database access and use policy
As part of its studies and research, LISER has collected large amounts of data from various projects the Institute has carried out since its creation. LISER has also conducted a significant number of surveys in the country and in bordering countries mainly concerning individuals and households, from which it has analysed and archived information.
LISER aims to increase the value of the data collected by making it available to the scientific community.
It is, therefore, necessary to lay down essential rules for accessing the Institute's different databases. These rules concern the confidentiality statutes that are to be complied with as well as general conditions of use and procedures for accessing the multiple databases.
This policy specifies the types of databases LISER makes available, as well as how they can be used, either :
Data access conditions
- (a) Externally, by user requests from the scientific community,
- (b) Internally, by all LISER employees or by visitors to LISER.
By default, all the databases owned or co-owned by LISER are accessible to all LISER employees on simple request (using a confidentiality declaration form
). There may be specific cases that differ, namely databases of which LISER is not the sole owner. For the latter case, each database has its own arrangements (generally a specific data agreement form).
For people external to LISER, access to data varies depending on the legal status and confidentiality level of the database requested. Therefore, depending on the database's confidentiality level, access may be granted only within LISER (physical entity) through an individualised and secure IT account. In all cases, access is requested using a form (see 'How to make a request').
The aim of our policy is to facilitate access to data for research. The rules laid down are not used to hinder research or any other arbitrary desire to control. Rather, the aim is to put researchers in a position of responsibility with regard to data whose dissemination may be limited due to legal obligations (protection of persons, professional secrecy, etc.) or due to the data producer's interest (privilege of use, right of quotation, etc.).
How to make a request
The data access procedures differ depending on the user and data status. In all cases, users must sign an individual commitment.
Data can be requested :
- By contacting the LISER Data Centre : firstname.lastname@example.org,
- Or by drawing up (if one is available for the database requested) a LISER Agreement on data access or provision. (downloadable).
Users provide information on their status and are requested to indicate which research project their request relates to. The published and signed documents must be sent by post to the following address :
