Comparative structure study
The largest recorded industry, Advanced materials, contains 40 records (29.4% of this 136-record cohort). The remaining cohort contains 96 records. The comparison concerns archive composition.
The recorded industry label Advanced materials accounts for 29.4% here (40/136), compared with 13.5% in the parent set (406/3,012), an absolute gap of 15.9 percentage points.
7/136 companies link to pages with existing source-supported excerpts (5.1% of the cohort). The other 129 records remain usable for archive composition, but do not support new operating case studies.
