The paper studies the relationship between key factors influencing senior entrepreneurship and the level of inclusiveness of seniors in entrepreneurial activity in Europe. The objective is to cluster countries with similar patterns in senior entrepreneurial inclusivity and to identify the factors leading to inclusive entrepreneurship of seniors and their social cohesion. The focus is on European countries which participated in Global Entrepreneurship Monitor (GEM) between 2001 and 2012, using GEM data as the main source for the analyses. Initially, the authors identify the key factors influencing entrepreneurial activity of seniors within Europe based upon data contained within the literature review. At the same time, utilizing the senior entrepreneurship inclusivity index, the authors measure the level of inclusiveness in each European country. Using the results of these analyses the authors subsequently implement a cluster analysis method to create clusters among European countries based upon the similarities in the relationship between the levels of senior entrepreneurship and entrepreneurial activity of the general population. This helps them identify countries with above average levels of senior entrepreneurship inclusivity. The results allow the authors to assess key similarities in clustered economies in terms of entrepreneurial culture and policies which have a major influence on senior entrepreneurship.
