Method
Data limits are stated, not hidden. A first number published and later corrected is preferable to a perfect number never released. This page brings together, in one place, the sources used across all Vespri reports and the limits of each — instead of leaving them scattered in the appendices of individual issues.
Public statistical and institutional bodies, public company financial statements, job-posting aggregators and recruiting portals with accredited data access — always within each source's terms of use.
Every report includes a methodology sheet: what the data captures, what it doesn't, and where a figure should be read as a lower bound, not an absolute value.
Publish, then expand: more countries, more companies, more sectors in later versions — with revisions always tracked.
A public monitoring database on European corporate restructuring: 31,427 events, 2002-2026, 29 countries (EU-27, Norway, United Kingdom). It records the year of announcement, not the year jobs actually disappear — a multi-year plan weighs in full on the announcement year. UK coverage stops after January 31, 2020 (Brexit). Sector classification is heuristic, based on company-name recognition and spot-checked: roughly 90% of all events concern non-engineering sectors and are excluded from the analysis.
81 listed European stocks, 7 sectors, 2022-2025 history — a structural limit of free access to this type of data, not extendable beyond 4 fiscal years without a paid provider. Any Sector×Year cell with fewer than 3 companies with valid data is excluded from charts and rankings, to prevent a single stock from passing as a sector average.
A job-posting aggregator with API data access: breadth across seven sectors, four geographic areas, dozens of companies — but only a truncated snippet of the description. Percentages from this source are a lower bound on the real prevalence of each skill, not an exact share.
Direct access to the public endpoints exposed by the recruiting platforms of the companies analyzed: full posting text, but only for the 27 companies — out of 93 total — that expose an accessible endpoint. 5,887 of the 16,386 total postings, averaging 4,199 characters per posting.
