Employment and unemployment are important subjects that draw attention to participants in economic occurrences of all countries. Monitoring of their dynamics attracts particular attention of the public in transitional countries. Due to numerous particularities accompanying transition, labour market problems in Serbia will continue being the main concern of various economic analyses for a long time. Information on labour market movements is collected and published by the National Employment Service (NES) and the Statistical Office of the Republic of Serbia (SORS). NES gathers and analyzes statistical data from the field of unemployment and employment. Statistical reports of the NES are one of the sources on which basis analysing and monitoring occurrences and tendencies/movements of unemployment and employment in the labour market, their interdependence and relation are performed. They also represent one of the bases for creation and guidance of the Active Employment Policy programme and improvement of unemployment reduction measures. At the same time, SORS gathers data and publishes the “Labour Force Survey”, which is a research that provides the most comprehensive view on labour force characteristics and labour market occurrences. SORS studies are conducted by applying methodological solutions that are adjusted to recommendations and standards of the International Labour Organization – ILO and requirements of EUROSTAT (European Statistical Office), thus providing the most important source for international comparison of labour statistics data of the Republic of Serbia with other countries. Non-compliance of authority of those involved in gathering, analysing and publishing data from the labour market, as well as the scope, type and dynamics of research, points out to the need to apply a unified system solution at national level.
