Research findings
Comparative structure study
The largest recorded industry, Advanced equipment, contains 79 records (30.3% of this 261-record cohort). The remaining cohort contains 182 records. The comparison concerns archive composition.
The recorded industry label Next-generation information technology accounts for 12.3% here (32/261), compared with 30.4% in the parent set (1,117/3,671), an absolute gap of 18.2 percentage points.
13/261 companies link to pages with existing source-supported excerpts (5.0% of the cohort). The other 248 records remain usable for archive composition, but do not support new operating case studies.

Excluding this cohort, the recorded industry label Next-generation information technology covers 1,085/3,410 remaining records (31.8%), an absolute gap of 19.6 percentage points from this cohort.
Concentration and cross-sectional structure
The full industry distribution has 10 labels; the top 3 contain 186/261 records (71.3%).Other known labels contain 75 records.
For 261 records with known labels, the effective category count is 4.8, versus 10 actual labels. Definitions and scope are in the methodology.

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
223 of this cohort’s 261 records link through existing company-ID mappings to 2026 lists from all jurisdictions (85.4%). This intersection measures list linkage, not successful recognition or company growth.

| National list records linked to this cohort’s IDs | 223 | 0 | 223 | 223 |
List rows and company IDs are separate counts, not new firms or final recognition.
