Filter-difference study
Against the 110-record Fasteners Springs Basic Components Keyword Candidate Study, this 102-record cohort shares 102 records. Only 0 occur here and 8 only in the reference; the union contains 110. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |
|---|---|---|---|
| 102 | 102 | 0.5% | 2026-10-16 |
An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Insulating, heat-dissipating and thermally conductive materials: 0/102 here versus 2/110 in the reference, an absolute difference of 1.8 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Insulating, heat-dissipating and thermally conductive materials | 0/102 | 2/110 | -1.8 |
| Critical basic components | 15/102 | 18/110 | -1.7 |
| Automotive structural parts and components | 20/102 | 20/110 | +1.4 |
| Instrumentation and testing equipment | 16/102 | 16/110 | +1.1 |
| Adhesives and sealing materials | 0/102 | 1/110 | -0.9 |
Zero means no recorded label, not no business; multi-label cells overlap.
