<p>Data Literacy, encompassing the necessary skills for working with data, stands as a pivotal competency in the knowledge economy. Despite its prominence, there is currently no unified definition of Data Literacy, along with its constituent skills. This study focuses on Data Literacy in the workplace, particularly in transversal skills applicable to any worker, not exclusively to technicians or specialists, employing two methodologies: (1) bibliometric analysis to assess scientific production, and (2) a systematic literature review using the PRISMA methodology. The results reveal a significant increase in scholarly output on Data Literacy, indicating an exponential growth phase although with a limited number of references concerning the study of transversal skills applicable to all workers. Moreover, they demonstrate the relationship between Data Literacy and other literacies. Finally, we identify the core competencies associated with Data Literacy and propose a definition related to various profiles essential for companies aiming to enhance their data management capabilities or develop training programs to become data-driven enterprises.</p>
