Abstract:

The Survey of Business Owners (SBO), a survey conducted every five years, is the most comprehensive survey source of basic economic statistics on businesses owned by poeople of Black, Hispanic, Asian-Pacific Islanders, or American Indian-Native Alaskan ancestry and women. It publishes information on the aggregate number, receipts, payroll, and employment of minority-owned sole proprietorships, partnerships, and corporations. While SBO is designed to provide reliable estimates of race/ethnicity at the state by two-digit standard industrial classification, requests are often received for estimates at more detailed geographic and/or industry levels. Direct survey estimators fail for these finer levels of detail because the sample is not representative at these levels. We have proposed a method of mass imputation whereby data is imputed both for nonresponding and nonsampled cases to create a complete universe. The results are encouraging when the estimates from this method are compared to the direct estimates in small areas.
