Istanbul vs Gaziantep
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Istanbul leads on any axis where its bar is higher, Gaziantep where its is. The cost bar uses a higher-is-cheaper scale, so Gaziantep's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Istanbul | Gaziantep |
|---|---|---|
| Livability | 68 | 61 |
| Cost (higher=cheaper) | 45 | 49 |
| Climate | 100 | 73 |
| Safety | 63 | 64 |
| Summer °C | 23.3 | 28.6 |
| Winter °C | 5.8 | 4.0 |
| Top disaster risk | wildfire | wildfire |
Istanbul vs Gaziantep: the short answer
Istanbul comes out ahead on overall livability (68/100), modestly above Gaziantep (61/100). The two cities diverge most on climate. On affordability Gaziantep is the cheaper base — nearly identical prices on our cost index (Istanbul 45 vs Gaziantep 49, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Gaziantep runs warmer in summer (about 28.6°C peak vs 23.3°C in Istanbul), while winter lows sit near 5.8°C in Istanbul and 4.0°C in Gaziantep. On natural-disaster exposure Gaziantep is the safer choice (safety 64/100); the dominant modelled hazard is wildfire for Istanbul and wildfire for Gaziantep.
Which city should you choose?
- On a tight budget → Gaziantep — lower everyday costs..
- You want warmth → Gaziantep — hotter summers.
- Safety is the priority → Gaziantep — lower disaster risk.
- Best all-rounder → Istanbul — highest overall livability.
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.
