The Digital Economy and Society Index (DESI) is the main tool used by the European Commission to measure the level of digitalization in EU countries. Although Poland achieved a score of 40.5 out of 100 in the index, placing it 24th among EU countries, the development level of several indicators is approaching that of the classification leaders, including Finland, Denmark, and Estonia. Despite the DESI methodology making it very difficult for member states to make any progress in the ranking, Poland is among the countries that are catching up fastest with the leaders. Currently, the index is undergoing a major transformation as part of the implementation of the Digital Decade, a new EU digitalization strategy. Therefore, changes are necessary in DESI to ensure a more objective assessment of the level of digitalization in individual EU countries, as outlined in the report by the Polish Economic Institute, "How to Measure the Digital Decade - Recommendations for an Evolution of the DESI Index."
