Pattern analysis from 98,992 WSIAT decisions showing which industries experience which injury types
⚠️ Data Limitation: Current extraction includes injury type patterns (keyword matching) but NOT industry classifications. The matrix below shows estimated correlations pending full extraction. Industry data exists in WSIB Premium Rate Group data (664 rate groups available). Real injury patterns available: Back/Spine (15,177 cases), Hearing Loss (9,650), Chronic Pain (7,502), etc.

Injury Pattern Summary (Real Data - All Industries Combined)
Back/Spine Injuries: 15,177 cases (15.3% of all decisions) - Most common injury type
Hearing Loss: 9,650 cases (9.7%) - Second most common, indicates high noise exposure industries
Chronic Pain: 7,502 cases (7.6%) - Third most common, complex ongoing conditions
Shoulder Injuries: 6,234 cases (6.3%) - Upper body repetitive strain
Knee Injuries: 4,891 cases (4.9%) - Lower body impact/repetitive
Amputation: 2,890 cases (2.9%) - Severe machinery/crushing injuries
Concussion: 2,456 cases (2.5%) - Head trauma from falls or impacts
Note: Industry × injury correlations require combining WSIAT decision text with WSIB Premium Rate Group industry codes. This analysis is planned for Phase 2 extraction.
