City-proper / metro population estimates. Size is one input — scroll on for cost of living, salary equivalence and quality-of-life scoring.
Johannesburg edges out Mexico City on the Mundevo composite, 5.1 to 5.1 out of 10 — a narrow 0.0-point margin across safety, healthcare, air quality and cost.
The composite gap is small enough that one weighted axis can flip the result. Use the per-axis breakdown below to see which city wins your specific priorities — someone optimizing for healthcare can land on a different answer than someone optimizing for affordability.
Run the salary calculator for both cities at your target lifestyle before deciding — Johannesburg winning on quality doesn't mean the gross-salary requirement also lands in your favor. If you're on a balanced tier, the cost-of-living pages for each city carry the full monthly basket and the gross-salary figure.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
| Axis | Johannesburg | Mexico City | Winner |
|---|---|---|---|
| Affordability | 7.0 | 6.6 | Johannesburg +0.4 |
| Quality of life | 4.2 | 4.6 | Mexico City +0.4 |
| Remote-work friendliness | 4.9 | 5.0 | Mexico City +0.1 |
| Healthcare | 4.3 | 4.3 | Johannesburg +0.0 |
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%)39
- Rent index (weight 40%)16
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Johannesburg: ((100 − 39)/100 × 0.6 + (100 − 16)/100 × 0.4) × 10 = 7.
Johannesburg sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)18
- Healthcare index (weight 35%)62
- Air quality index (weight 25%)52
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Johannesburg: (18/100 × 0.4 + 62/100 × 0.35 + 52/100 × 0.25) × 10 = 4.2.
Johannesburg has a mixed quality profile. Safety: poor; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)60 Mbps
- Effective income tax (lower = better) (weight 30%)18.0%
- Cost-of-living (lower = better) (weight 25%)39
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Johannesburg: (min(60/300, 1) × 0.45 + (1 − 0.18) × 0.3 + (100 − 39)/100 × 0.25) × 10 = 4.9.
Johannesburg works for remote work but isn't optimized for it: internet 60 Mbps, income tax 18%, cost index 39.
Healthcare
- Healthcare quality index (weight 70%)62
- Healthcare out-of-pocket / month (lower = better) (weight 30%)800
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Johannesburg: (62/100 × 0.7 + max(0, 1 − 800/500) × 0.3) × 10 = 4.3.
Johannesburg has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~800 ZAR/month. Cross-border insurance closes the gap.

Affordability
- Cost-of-living index (weight 60%)38
- Rent index (weight 40%)28
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Mexico City: ((100 − 38)/100 × 0.6 + (100 − 28)/100 × 0.4) × 10 = 6.6.
Mexico City is mid-range on absolute cost. Affordability is reasonable but not its main advantage.
Quality of life
- Safety index (weight 40%)35
- Healthcare index (weight 35%)62
- Air quality index (weight 25%)42
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Mexico City: (35/100 × 0.4 + 62/100 × 0.35 + 42/100 × 0.25) × 10 = 4.6.
Mexico City has a mixed quality profile. Safety: fair; healthcare: good; air: fair. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)50 Mbps
- Effective income tax (lower = better) (weight 30%)10.0%
- Cost-of-living (lower = better) (weight 25%)38
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Mexico City: (min(50/300, 1) × 0.45 + (1 − 0.1) × 0.3 + (100 − 38)/100 × 0.25) × 10 = 5.
Mexico City works for remote work but isn't optimized for it: internet 50 Mbps, income tax 10%, cost index 38.
Healthcare
- Healthcare quality index (weight 70%)62
- Healthcare out-of-pocket / month (lower = better) (weight 30%)800
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Mexico City: (62/100 × 0.7 + max(0, 1 − 800/500) × 0.3) × 10 = 4.3.
Mexico City has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~800 MXN/month. Cross-border insurance closes the gap.
Monthly cost delta: Johannesburg vs Mexico City
Normalized to ZAR at 1 MXN = 0.9302 ZAR.
| Category | Johannesburg | Mexico City | Change |
|---|---|---|---|
| housing | ZAR 9,000 | MX$9,500 | -2% |
| food | ZAR 5,000 | MX$4,200 | -22% |
| transport | ZAR 1,100 | MX$800 | -32% |
| utilities | ZAR 2,500 | MX$1,200 | -55% |
| leisure | ZAR 4,500 | MX$3,000 | -38% |
| healthcare | ZAR 800 | MX$800 | -7% |
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 housing: Mexico City spends 9.4 percentage points more of its budget on it (49% vs. 39%). If you're sensitive to that category, weight the per-axis scores accordingly.
Salary equivalence: Johannesburg ↔ Mexico City
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Johannesburg = 39, Mexico City = 38); currency-converted at 1 MXN = 0.9302 ZAR. Tax differences are not modeled.
| Johannesburg gross | Mexico City equivalent |
|---|---|
| ZAR 40,000 | MX$41,897 |
| ZAR 75,000 | MX$78,558 |
| ZAR 120,000 | MX$125,692 |

| MX$75,000 | ZAR 71,603 |
| MX$120,000 | ZAR 114,565 |
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.

How this page is calculated
Data sources
- AI-estimated data for Mexico City. Cost indices, rent indices, quality scores and monthly breakdown for Mexico City were generated by an AI model as a directionally-correct starting point, not a primary-source measurement. The comparison delta carries the same ±15-25% uncertainty band on the AI-side; pressure-test against local sources before drawing conclusions about individual categories.
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-06-10 (Johannesburg) and 2026-05-24 (Mexico City).
- FX rate. 1 MXN = 0.9302 ZAR, 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.

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 Johannesburg 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.
