Does this count include self-employed owners with no staff?
No. County Business Patterns covers establishments with at least one paid employee. A sole proprietor with no employees is counted in a separate Census series called Nonemployer Statistics, which this site does not use yet, so the real number of people working in this trade is higher than the figure shown.
