From Source to Product Signal

Test a Product Idea in Four Steps

O*NET publishes occupation codes, titles, and descriptions as downloadable database files under CC BY 4.0. Start with the Occupation Data CSV, not the paid-product Web Services free-tier. Titles are a taxonomy, not a vacancy count, and O*NET is a trademark of USDOL/ETA.

1

Check the Setup

  • Python 3.10 or newer
  • A notebook environment such as Jupyter or Google Colab
  • An internet connection
2

Access the Data

  1. 1.Open the database page and read the CC BY attribution requirements.
  2. 2.Download the published Occupation Data file, not services.onetcenter.org.
  3. 3.Keep O*NET-SOC codes as text and credit O*NET 30.3 Database.
Open Official Source

Run the Python Example

Install the packages, then run the notebook cell.

python -m pip install pandas

import pandas as pd

occupations = pd.read_csv(
    "https://www.onetcenter.org/dl_files/database/db_30_3_text/Occupation%20Data.txt",
    sep="\t",
)
print(occupations.head())
print(occupations.columns.tolist())

Test a Useful Signal

Browse Published O*NET Occupation Titles

Test whether the Occupation Data file can power a bounded job-profile lookup.

  1. 01Keep O*NET-SOC code, title, and description as published.
  2. 02Search for one occupation family by title keywords and count matching codes.
  3. 03Attribute O*NET 30.3 Database under CC BY 4.0 and explain that titles are not a measure of hiring demand.
