France Inflation Data (per Department, Index Type, Index Variation, Household, And Product Type)

Hi!

I struggled a lot to find the inflation data for France from an official source. I either found articles from INSEE (National Institute for Statistics and Economic Studies) on the inflation for each month which had a link for that data, and even that was only a subset of all the data for that month. Or I found auxiliary websites that didn’t cite the source for their data.

I also looked for official APIs but didn’t find something that directly provided the consumption index (inflation index) or a preprocessing of it (year-over-year variation for example). But I stumbled randomly on this https://www.insee.fr/fr/statistiques/series/102342213 (it’s an official source, it’s the INSEE) for which the title might be confusing. The title suggests that the data there is grouped by products and detailed products (a special nomenclature named COICOP).

I preprocessed it here https://github.com/ReinforcedKnowledge/france-inflation-data-cleaned (includes raw data, preprocessing scripts and preprocessed data). The README is in French but it explains the data a bit and explains how I got granular datasets from that big raw data. I found it a bit messy and confusing at the beginning when I started looking at it, but I was able to extract every unique combination of the modalities (region/department, index type, index variation, if product is under the COICOP nomenclature, household type).

I hope it can help if someone is looking for that data or understand it because it really took me some time and effort to find it and make sense of it.
