The Lightcast Skills Taxonomy is an open-source library of 32,000+ skills gathered from hundreds of millions of online job postings, profiles, and resumes—updated every two weeks. The Taxonomy collects real-time data from over 40,000 sources daily, contributing to a database with over 1 billion job postings and billions of other data points. These data are combined with curated input from other statistical sources, like government agencies, to provide the most complete view possible of the fast-changing labor market. This information is used in businesses, communities, and education providers who need the granular details and big-picture trends for their planning and improvement efforts.
