Female entrepreneurs do not exist in a vacuum but are influenced by previous work experience and networks so it is no wonder that women’s entrepreneurial activity tends to be concentrated in specific sectors. Occupation crowding in terms of jobs being considered ‘male’ or ‘female’ jobs influences entrepreneurship crowding resulting in female entrepreneurial activities being concentrated in a small number of sectors. In this paper, we (1) Introduce a quantitative indicator that measures the male/female labor force balance and calculate it for a 30 country sample; (2) Identify the sectors which are most affected by occupational and entrepreneurship crowding; and (3) Discuss the policy implications of these findings.
