Where this industry stands

MeasureValue
Net establishment formation, 5yr-0.60%
Standing among all industries35th of 287
Reads asdying faster than it is forming
Signal strength, backtestedρ 0.57 over 4 windows

Among 287 industries, this one sits at the 35th percentile on net establishment formation over 2019-2023 — it is dying faster than it is forming. That signal carries a measured rank correlation of 0.57 with the following decade's growth across 4 backtested windows, separating top and bottom deciles by 42.6 percentage points. It describes the INDUSTRY, not a business in it, and it was calibrated against establishment growth rather than returns to an operator.

65 of 100 rubric points are evidenced, 25 partially, 10 have no producer. No total score is rendered from that. PREDICTS is a separate question from EVIDENCE: a dimension can rest on a real sourced figure and have no measured relationship with what happens next.

Charged off—

Only 16 seasoned loans have reached an outcome in this industry — too few to publish a rate. That is a thin lending history, which is itself worth knowing before assuming a lender will fund your deal. SBA 7(a) FOIA data, FY2011–FY2026. Loans to acquire an EXISTING business, separated from start-up lending by the SBA's own business-age field. Charge-off is measured on RESOLVED loans only — a loan approved last year has not had time to fail.

What it costs to produce

MeasureValue
Margin on receipts54.1%
Computed asvalue added — receipts less cost of materials
Industry receipts$3.5bn

Computed by the Census Bureau, not by us. Economic Census 2022. Census collects a cost structure for this sector and collects none for most service industries; where it does not, this document shows labour share and refuses to call it a margin.

Payroll is 24.7% of receipts industry-wide across 281 firms. LABOUR SHARE, NOT MARGIN: Census publishes receipts and payroll and never cost of goods, so gross margin cannot be derived and is not claimed here. Enterprise receipts — a firm counted once at its total size, not per location. Census SUSB 2022.

What we do not hold

Gap
licence titles in this scope — none matched 'Welders, Cutters, Solderers, and Brazers', though it is licensed in 50 jurisdictions nationally. The title differs locally, or the record is held municipally.
occupation mix for NAICS 333994 — the labour statistics carry no rows at this level, so everything about occupations here, including the defining occupation and its licence gate, is measured at NAICS 333000, a broader grouping. Establishment counts are for 333994 itself.
licence coverage — the register holds 54 of 56 US licensing jurisdictions, and 2,504 of its records carry no jurisdiction at all. A count of 50 is out of 54 searched, not out of 56. The unsearched jurisdictions are not evidence of no licence.
bonding_required_usd — no producer, and not estimated

Stated rather than filled. An absence of match is not an absence of fact.

Verification

This document's content hash is below. Anyone can check it at ro.8thwavemedia.com/verify without an account and without taking our word for anything. A single altered character produces a completely different hash, so a document that verifies is a document nobody has revised.

Do not expect sha256sum of this file to match. A document cannot contain its own hash — adding the hash would change it. The hash above covers the report content as issued, excluding this verification panel. That is stated here rather than left to be discovered, because a reader who hashes the file, gets a different answer and concludes the document was tampered with would be wrong for a reason we created.

Research against public records — not investment, legal, tax or accounting advice. No figure here is a prediction about your business. Figures describe an INDUSTRY; a business within it may do better or worse for reasons no public dataset records. Gaps are stated rather than filled: where a dimension has no evidence it is marked absent rather than estimated.
