Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 74 records (24.2% of this 306-record cohort). The remaining cohort contains 232 records. The comparison concerns archive composition.
The recorded industry label Producer services accounts for 10.5% here (32/306), compared with 5.1% in the parent set (221/4,365), an absolute gap of 5.4 percentage points.
252/306 companies link to pages with existing source-supported excerpts (82.4% of the cohort). The other 54 records remain usable for archive composition, but do not support new operating case studies.

Concentration and cross-sectional structure
The full industry distribution has 10 labels; the top 3 contain 190/306 records (62.1%).Other known labels contain 116 records.
For 306 records with known labels, the effective category count is 6.3, versus 10 actual labels. Definitions and scope are in the methodology.
| Recorded label | Records | Share of cohort |
|---|---|---|
| Advanced equipment | 74 | 24.2% |
| Next-generation information technology | 63 | 20.6% |
| Advanced materials | 53 | 17.3% |

A rule hit prioritises review; it does not establish that the entire field is wrong. One record can trigger several rules.
Intersection with 2026 local lists
4 of this cohort’s 306 records link through existing company-ID mappings to 2026 lists from all jurisdictions (1.3%). This intersection measures list linkage, not successful recognition or company growth.
