Unfortunately, there is no way to measure directly the total revenue of immigrant and native businesses. Thus, it is possible to determine how much money immigrant and native entrepreneurs are generating for themselves.
Income is important because it is one way to measure the size and success of a business.
The self-employment income figures suggest that immigrant entrepreneurs are slightly more successful than native entrepreneurs, at least in terms of generating income for themselves. However, this difference is not large enough to be statistically significant. Moreover, self-employment is certainly no guarantee of success for either group. Forty-two percent of natives and 40 percent of immigrant entrepreneurs either lose money or only break even. Clearly, self-employment provides only a modest income for natives and immigrants alike.
