DESI Index Dimensions (European Union) (https: //ec. europa. eu/digital-single-market/en/desi) • The Connectivity, dimension measures the deployment of broadband infrastructure and its quality. • The Human Capital/Digital skills dimension measures the skills needed to take advantage of the possibilities offered by digital. 38

DESI Index Dimensions (European Union) • The Use of Internet Services by citizens dimension accounts for a variety of online activities, such as the consumption of online content (videos, music, games, etc. ) video calls as well as online shopping and banking. • The Integration of Digital Technology by businesses dimension measures the digitisation of businesses and e-commerce. By adopting digital technologies, businesses can enhance efficiency, reduce costs and better engage customers and business partners. 39
