how to use this table
Census draws nonemployer firm counts (no paid employees, >=$1,000 receipts) from IRS Form 1040 Schedule C, 1065 partnership returns, and 1120 corporate returns by county FIPS. nonemployer_share = nonemployer_firms / (nonemployer + employer establishments).
W-2 employment; firms with employees (use CBP); informal/cash economy below $1,000 threshold; comparison with QCEW (different definitions).
$1,000 receipts threshold excludes very-small side income. NAICS classification of nonemployers can be noisy.
