In the context of the Global Innovation Index (GII), knowledge workers are highly skilled professionals whose main contribution to the economy is based on their ability to generate, manage, and apply knowledge. These professionals play a crucial role in the innovation process, as they use intellectual skills, creativity, and advanced knowledge to solve complex problems and create added value in their respective fields. Knowledge workers include engineers, scientists, researchers, analysts, software developers, highly specialized technicians, and other professionals involved in sectors such as research and development (R&D), information and communication technology (ICT), and education. The GII measures the impact of these workers by analyzing factors such as the density of researchers, the development of advanced human capital, and the diffusion of technical and scientific knowledge. The contribution of knowledge workers is fundamental to a country's economic competitiveness, as they foster technological innovation and adaptation to new markets and global challenges. Their presence and activity largely determine a country's ability to transform innovation into sustainable economic growth and social progress. The data refer to the period between 2013 and 2022.
