The Lightcast Occupation Taxonomy provides a granular, contextual framework derived from real-world job postings, employee profiles, and official government statistics that brings consistency and structure to workforce data. It consists of four categories:

• Career areas (e.g. Healthcare, Finance, Transportation) are the broadest occupational category in the Lightcast Occupation Taxonomy and generally map to different industries. They are designed to be useful in bringing together many similar occupations that are responsible for similar work tasks. Their overarching scope allows for a quick look at broad segments of the labor market. They provide an understanding of the defining skills that are necessary to enter any career within its scope.
  

• Occupation groups (e.g. Physicians, Banking and Lending, Truck and Bus Drivers) are clusters of occupations that share very similar skill or role requirements. They describe the different “fields” or “disciplines” available in the market for early- or pre-career students. They are subsectors of career areas.
  

• Occupations (e.g. Physician, Loan Officer, Tractor-Trailer Truck Driver) often overlap with actual job titles. They are designed to align easily with government taxonomies, undergraduate degree programs, and the career aspirations of workers entering a new industry for the first time.
  

• Specialized occupations (e.g. Surgeon, Mortgage Underwriter, Refrigerated Truck Driver) offer our most granular level of specificity, allowing for the closest look at supply and demand for a given role compared to the market, and also the clearest look at the skills required. They are characterized by unique and value-added sets of skills, roles, and responsibilities, as well as additional education or credentials beyond the minimum requirements of the entry-level role they may extend from.

Each specialized occupation is unique to its occupation, each occupation is unique to its occupation group, and each occupation group is unique to its career area. This prevents duplicate or overlapping data when analyzing more than one occupation.

The precision level of the LOT is intentionally designed to be both informative and accurate. It goes deeper into specifics compared to government systems like O*NET and SOC, without getting tangled in the intricacies of individual job titles. The LOT undergoes annual updates, striking a balance between stability and usefulness for longitudinal comparisons, while also promptly capturing newly emerging roles as they formalize within the economy.
