Entrepreneurship is becoming an important source of employment for women in many countries. There are different circumstances and motives that contribute to the decision to start a business. In this study, we developed a model that can estimate the probability of individuals becoming nascent entrepreneurs by opportunity or necessity. The model considers individuals' sociodemographic characteristics and European economies' perceived characteristics as oriented towards efficiency or innovation. Statistical logistic regression was used to test the model. The results show statistically significant differences between genders, European economies oriented either to efficiency or innovation, and entrepreneurs who are born out of opportunity or necessity.
