2 active routes / 6 not encoded

A zero means this source has no encoded row in that evidence domain. It is a boundary in the current observatory release, not a claim that the underlying institution publishes no relevant evidence. Indicator observations are shown as a separate normalized route and are not added to direct-domain totals.

Five-year deltas are published only for rows whose NAICS code and industry label are identical in the 2017 and 2022 Census tables. This strict match is a conservative screening rule, not an official NAICS concordance or evidence of causation. Revenue changes are nominal and are not adjusted for inflation.

A source dossier documents how this observatory uses one public record. It does not endorse every claim in that record, make unlike measures comparable, or extend the source beyond its stated product, geography, population, and vintage.
