Sydney vs Mexico City
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Sydney leads on any axis where its bar is higher, Mexico City where its is. The cost bar uses a higher-is-cheaper scale, so Mexico City's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Sydney | Mexico City |
|---|---|---|
| Livability | 57 | 60 |
| Cost (higher=cheaper) | 5 | 51 |
| Climate | 100 | 100 |
| Safety | 73 | 35 |
| Summer °C | 22.6 | 19.5 |
| Winter °C | 12.4 | 14.1 |
| Top disaster risk | storms (hurricane/cyclone) | earthquake |
Sydney vs Mexico City: the short answer
Mexico City comes out ahead on overall livability (60/100), modestly above Sydney (57/100). The two cities diverge most on cost of living. On affordability Mexico City is the cheaper base — a wide gap on our cost index (Sydney 5 vs Mexico City 51, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Sydney runs warmer in summer (about 22.6°C peak vs 19.5°C in Mexico City), while winter lows sit near 12.4°C in Sydney and 14.1°C in Mexico City. On natural-disaster exposure Sydney is the safer choice (safety 73/100); the dominant modelled hazard is storms (hurricane/cyclone) for Sydney and earthquake for Mexico City.
Which city should you choose?
- On a tight budget → Mexico City — lower everyday costs.
- You want warmth → Sydney — hotter summers.
- Safety is the priority → Sydney — lower disaster risk.
- Best all-rounder → Mexico City — 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.
