It's not a top-tier publication, to my knowledge, but the special issue on "Ethnicity, Cultural Diversity and Entrepreneurship" from the Global Business and Economics Review might be of interest to scholars looking at differential entrepreneurship experiences by demographic.  We continue to find big differences across different demographic groups in the United States in their entrepreneurial experiences such as recent articles touching on immigration or the litany of research looking at different minority populations from venture capital to broader research on minority entrepreneurship.
