Sofia vs Sliven
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Sofia leads on any axis where its bar is higher, Sliven where its is. The cost bar uses a higher-is-cheaper scale, so Sliven's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Sofia | Sliven |
|---|---|---|
| Livability | 62 | 68 |
| Cost (higher=cheaper) | 44 | 50 |
| Climate | 83 | 90 |
| Safety | 62 | 66 |
| Summer °C | 18.2 | 23.4 |
| Winter °C | -1.7 | 1.4 |
| Top disaster risk | earthquake | extreme cold / winter |
Sofia vs Sliven: the short answer
Sliven comes out ahead on overall livability (68/100), modestly above Sofia (62/100). The two cities diverge most on climate. On affordability Sliven is the cheaper base — nearly identical prices on our cost index (Sofia 44 vs Sliven 50, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Sliven runs warmer in summer (about 23.4°C peak vs 18.2°C in Sofia), while winter lows sit near -1.7°C in Sofia and 1.4°C in Sliven. On natural-disaster exposure Sliven is the safer choice (safety 66/100); the dominant modelled hazard is earthquake for Sofia and extreme cold / winter for Sliven.
Which city should you choose?
- On a tight budget → Sliven — lower everyday costs..
- You want warmth → Sliven — hotter summers.
- Safety is the priority → Sliven — lower disaster risk.

Data & methodology
Cost scores are normalised from World Bank price-level data. Climate figures (summer highs, winter lows) are drawn from 1991–2020 climate normals. Disaster-safety blends USGS earthquake history (magnitude 4.5+ within 300 km since 1980), tropical-cyclone basin position, flood/elevation exposure and Köppen climate zone. The livability score is the weighted composite of cost, climate and safety. All figures are planning indicators for 2026, not guarantees — verify specifics before relocating.
