text: **Two criteria were crucial for the selection of these indicators: availability of reliable data and the**
  **relevance of the indicators.**An ideal and complete set of indicators would cover even more indicators 
  than presented in this report, but major limits were set by the availability of reliable data. 
  The main data sources**comprise a large variety of quantitative datasets**, for example, Eurostat 
  statistics and EU-wide surveys (e.g. EU-OSHA’s European Survey of Enterprises on New and Emerging 
  Risks (ESENER), Eurofound’s European Working Conditions Survey (EWCS), Eurostat’s Labour Force 
  Survey (LFS) and its ad hoc modules, and the Flash Eurobarometer, detailed background reports on 
  risks, groups of workers, OSH systems and infrastructures (e.g. by EU-OSHA, Eurofound, the 
  Fundamental Rights Agency, etc.), and evaluations and assessments of the level of implementation of 
  OSH directives (e.g. by the Directorate-General for Employment, Social Affairs and Inclusion (DG 
  EMPL) or the Senior Labour Inspectors Committee (SLIC) surveys facilitated by the National Labour 
  Inspectorates). Regarding the description of developments beyond the EU, data were taken from the 
  International Labour Organisation (ILO), the World Health Organisation (WHO), the International Social 
  Security Association (ISSA), the United Nations (UN), the Organisation for Economic Co-operation and 
  Development (OECD), the International Commission on Occupational Health (ICOH) and the 
  International Association of Labour Inspection (IALI).
