In the analysis of the post-fordist society, the knowledge economy and knowledge work have a central place and deserve therefore special attention. These concepts play a key role in the public and political discourse, although their growing success and popularity come along with a lack of precise and agreed definitions or measurements. Starting from this tension, this article analyses the complex process of classification and measurement creation for both knowledge economy and work, and focuses on the conceptual aspects of the definitions as well as on the empirically based models. Conclusive considerations will then return on the relation between analytical categories and public discourse, arguing that also the uncertainty of definitions may play a strategic role in legitimising political positions.
