Research findings
Filter-difference study
Against the 19-record Geosynthetics Waterproof Materials Keyword Candidate Study, this 19-record cohort shares 15 records. Only 4 occur here and 4 only in the reference; the union contains 23. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |
|---|---|---|---|
| 19 | 19 | 0.1% | 2026-10-16 |
Deduplicated company IDs.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Special-purpose machinery: 0/19 here versus 1/19 in the reference, an absolute difference of 5.3 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Special-purpose machinery | 0/19 | 1/19 | -5.3 |
| Functional materials and advanced-material platforms | 7/19 | 8/19 | -5.3 |
| Refractory and thermal-insulation materials | 1/19 | 0/19 | +5.3 |
| Adhesives and sealing materials | 1/19 | 0/19 | +5.3 |
| Carpet and home-textile manufacturing | 1/19 | 1/19 | +0.0 |
Zero means no recorded label, not no business; multi-label cells overlap.
