LinkUp Legacy ONET System Migration

Overview

The ONET dataset has been updated from the legacy ONET system to ONET V3, based on the ONET-SOC 2019 taxonomy. The underlying data has been remodeled, and the complete historical dataset has been backfilled to reflect the new model. File formats are unchanged.


Changes & Updates

Transition to ONET V3 (ONET-SOC 2019)

What changed: The dataset now reflects ONET V3, built on the ONET-SOC 2019 occupational taxonomy. The legacy ONET model has been replaced.

Research impact: Any research pipelines or analyses built on the legacy ONET data are now referencing a remodeled dataset. Researchers should re-validate any occupational mappings, crosswalks, or derived variables against the ONET-SOC 2019 taxonomy to confirm continued accuracy.

Technical details:

  • ONET version in effect: ONET-SOC 2019

Historical Data Backfill

What changed: The complete historical dataset has been updated to align with the new ONET V3 model.

Research impact: Historical records previously sourced from the legacy ONET model now reflect the ONET V3 remodeling. Researchers using historical ONET data should be aware that longitudinal comparisons made against data pulled prior to this update may reflect differences attributable to the model change rather than true underlying shifts in the data.

Technical details:

  • Backfill scope: Complete dataset
  • Backfill method: Updated to match the new model in the full files
