Data Warehouse Labour Market and Social Protection (DWH LM&SP) – industrial accidents and occupational diseases

Datawarehouse Arbeidsmarkt en Sociale Bescherming (DWH AM&SB) – arbeidsongevallen en beroepsziekten

Summary

Strengths The typical strengths associated with administrative data apply. The use of administrative data is cost-effective, data quality is high, non-response is inexistent, etc. Specifically for life-course researchers, there are several added advantages, such as lack of attrition in between waves, lack of memory bias, etc. Typical for the Belgian situation is that all administrative datasets contain the National Register number and can therefore accurately be linked. Weaknesses Apart from the typical weaknesses of administrative data (e.g. lack of data on opinions, motivations etc.), the following problems can be mentioned: (1) There is no information on educational levels; (2) Due to an evolution in register systems, the data contain some statistical breaks; (3) Data on personal and household characteristics only become available with a three year time lag; (4) Information on the Data Warehouse Labour Market and Social Protection is only available in French and Dutch; (5) Belgian social security is extremely complex. As a consequence, the data that follow from it are also highly technical. This means that it is almost impossible to use the data without a thorough and detailed knowledge of the Belgian social security system. We therefore strongly advise foreign researchers to collaborate with Belgian research teams that have experience with the data.

Coverage of main and cross-cutting topics
The DWH LM & SP is the most important dataset to study social systems and welfare in Belgium. Data on employees incapacitated from work as a consequence of industrial accidents are provided by the Fund for Industrial Accidents `Fonds voor Arbeidsongevallen / Fonds des accidents du travail`); data on employees incapacitated from work as a consequence of an occupational disease are provided by the Occupational Diseases Fund `Fonds voor Beroepsziekten / Fonds des maladies professionnelles`.

Linkage

Standardisation
NACE-coding is used (i.e. statistical classification of economic activities in the European Community, developed by Eurostat)

Possibility of linkage among databases
The National Register number is integrated in all administrative datasets. In this way, information available in the Data Warehouse Labour Market and Social Protection can be linked to data from the National Register `Rijksregister / Registre National`, containing additional information on personal and household characteristics. As many other administrative datasets and survey datasets contain National Register numbers, it becomes possible to link the Data Warehouse Labour Market and Social Protection data to several other datasets. In this regard, it is important to notice that the Privacy Commission has stated under what conditions survey data from Statistics Belgium can be linked to the Data Warehouse Labour Market and Social Protection.

Data quality

Entry errors if applicable
General information on data quality of the DWH LM&SP: Data quality is high. However, given the detail of the information, data cleaning is far from straightforward and requires a thorough understanding of Belgian social security. Given the complexity of the recoding that is needed to make the data available for scientific research, errors can occur. These errors can be adjusted in collaboration with the Crossroads Bank for Social Security. Changes in legislation and registration can impact the content of the variables. Specific information related to the study of industrial accidents and occupational diseases: An important limitation is that at this moment, information on those permanently incapacitated from work is not available, the reason being that these data are dispersed over various private insurers. However, they will be available from 2014 onwards. Industrial accidents or occupational diseases insurance is not part of social security for the self-employed. For civil servants, the period of absence following work incapacity cannot be distinguished from periods worked.
