  • Notes: Estimations describe the OLS relationship between log yearly income of individuals and entrepreneurial activity of their ethnic group. Sample is taken from 2000 Census IPUMS. Sample includes immigrant males who arrived into the United States at age 16 or later and who are aged 22–70 in 2000. Estimations include fixed effects for the following person-level traits (category counts in parentheses): age (5), age at immigration for migrants (5), education (4), and English language fluency (2). Regressions use person weights and cluster standard errors by ethnic group.
