Research in urban economics has demonstrated that a concentration of human capital has a positive impact on economic growth (Shapiro, 2003; Simon, 1998) and that the level of human capital (in terms of the population’s level of education) constitutes a competitive advantage (Glaeser & Saiz, 2003; Glaeser, Sheinkmen & Sheifer, 1995; Shapiro, 2005). Therefore, the capacity of cities to attract a qualified and high-skilled workforce such as engineers and scientists is an asset regarding economic growth and urban competitiveness. Students in science and technology are supposed, once they graduate, to be part of the creative class and also according to recent research, the workforce in science and technology as a professional occupation is supposed to have a major impact on regional development (Beckstead and Brown, 2006). This workforce can also be assimilated to the concept of knowledge workers, which refers to a workforce with a high level of education and which can be defined according to their professional activity; this includes engineers but also professionals in the financial domain, amongst others. Peter Drucker (1994) coined this term and refers to knowledge workers as professionals with a high education background who apply their knowledge to the development of new products and services; this type of workforce is considered as a key component of success in the present economic context.
