“The majority of all business establishments in the United States are nonemployers, yet these nonemployer establishments average less than 4 percent of all sales and receipts nationally.”
“Most nonemployers are self-employed individuals operating a very small unincorporated business, which may or may not be the owner’s principal source of income.”
Here’s a handy chart of how the nonemployers are distributed by industry.
“The three states with the largest percentage of nonemployer establishments are Texas (79.5 percent), Georgia (79.4 percent) and Florida (79.0 percent). North Dakota is the only state where more than 30 percent of the establishments have paid employees.”
Interesting what the surrounding context is for self-employment these days.
