Tel AvivWhy Data Scientist pay in Lyon sits 50% below the France average
Lyon, FR posts a data scientist median of 66 600 €, which is 50% under the France average. The useful question is whether lower prices (COL index 100) and a modeled 1-bedroom near 1 420 €/month close that gap in real life.
Data scientists turn raw data into insight using statistics, machine learning, and clear communication. In Lyon, FR the title is noisy: some “data scientist” seats are analyst work paid near 66 600 €, while production ML seats push toward 66 600 €. The 66 600 € median is the blended market, not a single job family. Employers screening data scientists in Lyon, FR still list Python, SQL, Statistics, and Machine learning as core. The local band runs from about 44 200 € at the 10th percentile to 100 000 € at the 90th.
The percentiles on this page are observed metro figures for Data Scientist in Lyon, FR, not a national median multiplied by a pay index. That matters: you are looking at how this labour market actually priced the role, including local industry mix. They are still estimates of the market — not a promise of what one employer will offer.
Lyon is one of 2 France metros we can compare for this role. Paris leads this comparison at 99 100 € (+49% vs Lyon). Use those gaps to test a relocation thesis: a 15% cash raise that lands in a much more expensive metro can disappear in rent.
Lyon’s COL index (100) sits nearer the global baseline, so headline and adjusted pay are not far apart (66 600 € vs 66 600 €). Rent still matters: the 1-bedroom model is 1 420 € / month, about 34% of take-home, with leftover near 1 150 €.
If you are comparing a Lyon office offer with a location-flexible one, the France national median for this role is about 132 000 €. Local pay is 50% lower — a 65 400 € gap. Remote employers often anchor to the national figure; on-site employers in Lyon are anchoring to this page.
World Bank consumer-price inflation for France was about 0.9% in 2025; an illustrative model tied to inflation and the occupation’s outlook suggests pay has risen about 19% over the last few years. Passeport Talent / work permit is the usual skilled-hire route (moderate for typical hires): Qualified employees can use Passeport Talent or employer-backed work authorisation; thresholds and paperwork vary by skill level and contract length. At 1.6× France GDP per capita, this median is around a typical national living standard. Unemployment was about 7.5% in 2025. None of that is tax, immigration, or career advice — run the calculators and confirm rules officially.
How to read a data scientist offer in Lyon
Start with gross cash, not the recruiting headline. If an offer lands near 66 600 €, you are in the lower half of this metro’s observed distribution; near 66 600 € you are already paid like a stronger local hire. Then subtract a realistic tax path (simplified national effective rate here is about 25%, leaving 49 950 € a year) and a housing number you would actually accept — not only the 1 420 € model.
Because the 90th percentile is about 2.3× the 10th, two data scientist jobs in Lyon can be different careers that share a title. Ask what sits in the package (bonus, overtime, equity, on-call) before you treat 66 600 € as a fair target.
Demand and the data scientist pipeline
Occupation-level employment for data scientists is projected at about +35% over ten years. That is a national sketch of demand, not a forecast that Lyon will hire at that rate. Local openings still follow Lyon’s industry mix — hospitals, studios, public employers, or product companies — which is already baked into the observed percentiles more than into the outlook percentage.
