Open data: every euroflation series as CSV

Data dictionary

• Countries use ISO 3166-1 alpha-2 codes, so Greece is GR (Eurostat writes EL). EA21 is the euro area and EU27 the European Union. geographies.csv maps every code to its Eurostat and ECB equivalent.
• In Eurostat series, EA21 is Eurostat's aggregate for the 21 current euro-area members, kept on that fixed membership for the whole history (HICP from December 2000). In ECB series it is the ECB's euro area in its changing composition (ECB code U2).
• is_flash marks HICP values that euroflation judged to be flash estimates, because the source was updated before the 10th of the following month. The final release replaces them. It is a rule of thumb, not a flag published by Eurostat.
• Publishers revise their figures. euroflation re-checks the latest periods of every series each day; older history is refreshed when a series is reloaded in full. retrieved_on tells you when each row was last checked.
• The HICP moved to a new classification (ECOICOP 2) in 2026. Values come from Eurostat's current dataset, prc_hicp_minr; where it has no value for an early period, from the discontinued prc_hicp_manr.
• The ECB policy-rate files have one row per change: each rate applies from period_start until the next row.
• The fuel files (fuel_petrol, fuel_diesel) are weekly pump prices including duties and taxes from the European Commission's Weekly Oil Bulletin, in euro per litre: the bulletin quotes euro per 1,000 litres and euroflation divides by 1,000. The bulletin is published on Thursdays for the Monday before; it skips some weeks around Easter and New Year. History is kept from 5 January 2015. EA21 and EU27 hold the Commission's own weighted averages, with the membership of the time.
• The Brent crude oil price is not in these files. The U.S. Energy Information Administration publishes it with spot prices from Refinitiv, an LSEG business, and the EIA's copyright page says that content licensed from private companies may be protected, so euroflation cannot license it under CC BY 4.0. The price is shown, with its source, on the Brent crude oil price page.

Updates and stability

New data is collected twice a day, at about 11:00 and 16:00 UTC. Each file is rebuilt after new data arrives, usually within minutes of the next request for it; that request may still receive the previous copy. A browser or network cache may keep an older copy for a few hours, so check retrieved_on.

Stability promise

1. v1 is the schema version, not a data vintage. Inside v1, columns are never renamed, removed or reordered, a column never changes meaning or unit, and file names never change. New indicators arrive as new files. A new column may only be added at the end, announced in the changelog.
2. A breaking change ships as /data/v2/ next to v1, and v1 keeps being served for at least 24 months with a deprecation notice.
3. File names are indicator codes (hicp_yoy, bond_spread_bund), which are never renamed.
4. A discontinued indicator keeps its URL and its frozen history, marked discontinued in catalog.csv.
5. No query strings or filters: every file is one fixed URL.

Changelog

• v1.0.0, September 2026: first release.
• 12 October 2026: brent_usd.csv and brent_eur.csv, published earlier that day, were withdrawn. Their source, the EIA's Brent spot price, comes from Refinitiv, an LSEG business, and cannot be redistributed under CC BY 4.0. The file-name promise below does not extend to them; the price stays on its page with the source named.
