Lyon comes out ahead overall — by a clear margin.
But the "winner" depends on what you care about. Here's who takes each dimension:
Composite scores
Overall: Lyon wins by 1.2 points
Population & size
Is Lyon bigger than Seattle?
Seattle is the bigger city: about 750k people versus Lyon's 520k — roughly 1.4× larger.

Distance
How far is Lyon from Seattle?
Lyon is about 8,430 km (5,240 mi) from Seattle in a straight line — roughly 10 h 40 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Lyon warmer than Seattle?
Lyon is the warmer city: January highs average 7°C vs 7°C, and July 28°C vs 24°C. Annual sunshine is comparable between the two.
| Month | Lyon | Seattle |
|---|---|---|
| January (high / low) | 7° / 1°C | 7° / 2°C |
| July (high / low) | 28° / 17°C | 24° / 14°C |
Semi-continental with Mediterranean influence. Warmer than Paris, four distinct seasons, sunnier than most French northern cities.
Oceanic. Famously gray and damp Oct-May, dry warm summers Jun-Sep. Year-round temperatures moderate; snow rare in the city itself.
Lyon scores 6.4 versus Seattle's 5.0, a 1.4-point gap that reflects stronger walkability, transit density, and European urban planning versus sprawling Pacific Northwest geography.
Seattle typically ranks higher on tech ecosystem and innovation metrics, but Lyon's integrated public transport and compact center give it the edge on livability fundamentals.
If urban infrastructure and walkable neighborhoods matter more than startup culture and weather, Lyon deserves serious consideration over Seattle's car-dependent layout.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Lyon | Seattle | Winner |
|---|---|---|---|
| Affordability | 3.2 | 1.0 | Lyon +2.2 |
| Quality of life | 6.8 | 6.7 | Lyon +0.1 |
| Remote-work friendliness | 6.5 | 7.2 | Seattle +0.7 |
| Healthcare | 8.4 | 5.2 | Lyon +3.2 |
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)77
- Rent index (weight 40%)55
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Lyon: ((100 − 77)/100 × 0.6 + (100 − 55)/100 × 0.4) × 10 = 3.2.
Lyon is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)60
- Healthcare index (weight 35%)80
- Air quality index (weight 25%)65
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Lyon: (60/100 × 0.4 + 80/100 × 0.35 + 65/100 × 0.25) × 10 = 6.8.
Lyon has a mixed quality profile. Safety: good; healthcare: excellent; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)220 Mbps
- Effective income tax (lower = better) (weight 30%)14.0%
- Cost-of-living (lower = better) (weight 25%)77
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Lyon: (min(220/300, 1) × 0.45 + (1 − 0.14) × 0.3 + (100 − 77)/100 × 0.25) × 10 = 6.5.
Lyon works for remote work but isn't optimized for it: internet 220 Mbps, income tax 14%, cost index 77.
Healthcare
- Healthcare quality index (weight 70%)80
- Healthcare out-of-pocket / month (lower = better) (weight 30%)40
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Lyon: (80/100 × 0.7 + max(0, 1 − 40/500) × 0.3) × 10 = 8.4.
Lyon combines excellent system quality with a manageable out-of-pocket cost (~40 EUR/month). Travel insurance still recommended for non-residents.

Affordability
- Cost-of-living index (weight 60%)92
- Rent index (weight 40%)88
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Seattle: ((100 − 92)/100 × 0.6 + (100 − 88)/100 × 0.4) × 10 = 1.
Seattle is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)55
- Healthcare index (weight 35%)75
- Air quality index (weight 25%)75
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Seattle: (55/100 × 0.4 + 75/100 × 0.35 + 75/100 × 0.25) × 10 = 6.7.
Seattle has a mixed quality profile. Safety: good; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)300 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)92
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Seattle: (min(300/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 92)/100 × 0.25) × 10 = 7.2.
Seattle combines fast internet (300 Mbps median), a 17% effective income tax and cost index 92 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)75
- Healthcare out-of-pocket / month (lower = better) (weight 30%)500
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Seattle: (75/100 × 0.7 + max(0, 1 − 500/500) × 0.3) × 10 = 5.2.
Seattle has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~500 USD/month. Cross-border insurance closes the gap.
Monthly cost delta: Lyon vs Seattle
Normalized to EUR at 1 USD = 0.9259 EUR.
| Category | Lyon | Seattle | Change |

| healthcare | €40 | $500 | +1057% |
Where each city's money goes
Two cities can have the same monthly total but very different shapes — one might burn 50% on housing while the other splits more evenly. The composition matters as much as the headline.
The biggest shape difference is healthcare: Seattle spends 8.2 percentage points more of its budget on it (10% vs. 2%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Lyon ↔ Seattle
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Lyon = 77, Seattle = 92); currency-converted at 1 USD = 0.9259 EUR. Tax differences are not modeled.
| Lyon gross | Seattle equivalent |
|---|---|
| €40,000 | $51,616 |
| €75,000 | $96,779 |
| €120,000 | $154,847 |

| $120,000 | €92,995 |
Equivalence here means same cost-of-living purchasing power, not same net take-home. Effective tax rates differ between countries; a salary equivalent on cost can still net more or less depending on the destination's tax regime. Use the calculator for tax-adjusted figures at a specific lifestyle tier.

- FX rate. 1 USD = 0.9259 EUR, used to normalize cost baskets.
- CityScoreCalculator. Four axes (Affordability, Quality of life, Remote work, Healthcare) computed with explicit weights and explanations. See per-axis calculation strings rendered on this page.
- ComparisonService. Per-category cost deltas (housing, food, transport, utilities, leisure, healthcare) normalized to the origin currency.
Update cadence

Calculation
For each of the four axes we compute an independent 0–10 score using the formulas printed beside each axis. The composite is the unweighted mean of the four axes. The overall winner is the city with the higher composite, unless the margin is under 0.05 points — in which case Lyon is shown first as a tiebreaker to keep results stable.
Limitations
- Climate is not scored — we don't yet hold a maintained climate dataset, so weather-driven preferences are not modeled.
- Tax differences between cities in the same country are not modeled (Spain and Germany don't have material regional differences for this dataset).
- Indices are population-level. Personal cost varies with neighborhood, employer benefits and family status.
- Quality-of-life axis weights (safety 0.4 / healthcare 0.35 / air 0.25) are editorial defaults — readers with strong preferences should re-weight manually.
