Abstract

This memo documents efforts to understand and improve the quality of data produced through Census Bureau business surveys by developing an imputation model for foreign-born ownership of businesses that can extend backward in time, to the 2002 Survey of Business Owners. It uses a model selection procedure that ultimately selects a random forest model with good out-of-sample prediction capability (AUC = 0.86). It then estimates that foreign-born individuals founded 16% of new employer businesses that started between 1998 and 2002. This estimate extends the longest known U.S. time series on immigrant entrepreneurship that does not rely on self-employment as a proxy for entrepreneurship.
