MeasurementBusiness formation contextbusiness formation context
NAICS 23 is linked to the Census BFS Construction industry bucket for descriptive national application and employer-formation context. Counts remain distinct from rates, and projected formations remain distinct from observed businesses.
MeasurementEmployment and earnings contextemployment earnings context
NAICS 23 is linked to the broad national CES Construction supersector for descriptive payroll, hours, and nominal-earnings context. Construction payroll jobs, hours, and earnings are broad national industry context, not evidence about contractor concentration, local hiring options, or worker bargaining power.

Graph contract
Relationship families stay separate
The atlas joins routes through encoded custody and context, never through name resemblance or an inferred corporate, legal, or causal relationship.
The atlas exposes only relationships declared in the current public data. A link or issue grouping does not make unlike measures comparable, establish ownership or control, define an antitrust market, assign liability, or show that a policy event caused an economic outcome.
Reusable graph packet
Carry node and edge custody into analysis
The packet preserves node type, canonical route, relationship family, source link, evidence label, confidence, and edge-specific guardrail.
