This dataset contains aggregated numerical data on Circular Economy-related job postings collected from LinkedIn across EU member states and selected non-EU countries (UK, USA, Switzerland, Norway). The data include total and normalized job posting counts (normalized by the total number of LinkedIn job postings per country), as well as counts filtered by key job attributes, including job operation mode (on-site, remote, hybrid), job type, experience level, and job function. Data were collected repeatedly over multiple dates during the period March 2025-June 2025, resulting in 22 datasets corresponding to distinct collection rounds. The dataset includes only aggregated counts and contains no personal or textual job content.
