For each O*NET-SOC code included, 10 primary and 10 supplemental related O*NET-SOC codes are listed. The related occupations in this file are developed using an approach which includes three important contributors to occupational similarity: what people in the occupations do, what they know, and what they are called.

The “Relatedness Tier” column assigns one of three categories to each link:

  • Primary-Short — Five most strongly related occupations after expert review.
  • Primary-Long — 6th to 10th most strongly related occupations after expert review.
  • Supplemental — 11th to 20th most strongly related occupations after expert review.

The file is displayed in four tab delimited fields with the columns named O*NET-SOC Code, Related O*NET-SOC Code, Relatedness Tier, and Index. The four fields are represented by one row. There are a total of 18,460 rows of data in this file.
