Distance
How far is Busan from Chicago?
Busan is about 10,670 km (6,630 mi) from Chicago in a straight line — roughly 13 h 20 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 Busan warmer than Chicago?
Busan is the warmer city: January highs average 8°C vs -1°C, and July 28°C vs 29°C. Chicago gets noticeably more sun — about 310 more sunshine hours per year.
| Month | Busan | Chicago |
|---|---|---|
| January (high / low) | 8° / 0°C | -1° / -8°C |
| July (high / low) | 28° / 22°C | 29° / 19°C |
Humid subtropical coastal — milder winters than Seoul, humid summers with a wet typhoon-influenced Jul-Sep. The beach city of Korea.
Continental humid. Brutally cold snowy winters (wind chill off Lake Michigan), hot humid summers. The four-season classic.
Busan edges out Chicago on the Mundevo composite, 6.6 to 5.1 out of 10 — a decisive 1.5-point margin across safety, healthcare, air quality and cost.
A 1.5-point composite gap is large enough that the result holds across most reasonable axis re-weightings. Still worth scanning the per-axis breakdown if you have a non-default priority (e.g. air quality matters more to you than the default 25% weight).
Run the salary calculator for both cities at your target lifestyle before deciding — Busan 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.
The exact scores and winners:
| Axis | Busan | Chicago | Winner |
|---|---|---|---|
| Affordability | 5.4 | 2.5 | Busan +2.9 |
| Quality of life | 7.3 | 5.9 | Busan +1.4 |
| Remote-work friendliness | 8.0 | 6.8 | Busan +1.2 |
| Healthcare | 5.6 | 5.3 | Busan +0.3 |
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%)65
- Rent index (weight 40%)18
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Busan: ((100 − 65)/100 × 0.6 + (100 − 18)/100 × 0.4) × 10 = 5.4.
Busan is mid-range on absolute cost. Affordability is reasonable but not its main advantage.
Quality of life
- Safety index (weight 40%)78
- Healthcare index (weight 35%)80
- Air quality index (weight 25%)55
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Busan: (78/100 × 0.4 + 80/100 × 0.35 + 55/100 × 0.25) × 10 = 7.3.
Busan scores good on safety, excellent on healthcare and good on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)300 Mbps
- Effective income tax (lower = better) (weight 30%)12.0%
- Cost-of-living (lower = better) (weight 25%)65
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Busan: (min(300/300, 1) × 0.45 + (1 − 0.12) × 0.3 + (100 − 65)/100 × 0.25) × 10 = 8.
Busan combines fast internet (300 Mbps median), a 12% effective income tax and cost index 65 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)80
- Healthcare out-of-pocket / month (lower = better) (weight 30%)45000
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Busan: (80/100 × 0.7 + max(0, 1 − 45000/500) × 0.3) × 10 = 5.6.
Busan has trade-offs in healthcare: quality is excellent, typical out-of-pocket cost is ~45000 KRW/month. Cross-border insurance closes the gap.

Chicago 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%)45
- Healthcare index (weight 35%)72
- 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 Chicago: (45/100 × 0.4 + 72/100 × 0.35 + 65/100 × 0.25) × 10 = 5.9.
Chicago has a mixed quality profile. Safety: fair; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)250 Mbps
- Effective income tax (lower = better) (weight 30%)17.0%
- Cost-of-living (lower = better) (weight 25%)78
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Chicago: (min(250/300, 1) × 0.45 + (1 − 0.17) × 0.3 + (100 − 78)/100 × 0.25) × 10 = 6.8.
Chicago works for remote work but isn't optimized for it: internet 250 Mbps, income tax 17%, cost index 78.
Healthcare
- Healthcare quality index (weight 70%)72
- Healthcare out-of-pocket / month (lower = better) (weight 30%)450
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Chicago: (72/100 × 0.7 + max(0, 1 − 450/500) × 0.3) × 10 = 5.3.
Chicago has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~450 USD/month. Cross-border insurance closes the gap.

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: Chicago spends 14.3 percentage points more of its budget on it (53% vs. 38%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Busan ↔ Chicago
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Busan = 65, Chicago = 78); currency-converted at 1 USD = 1370.3704 KRW. Tax differences are not modeled.

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.

Remote work logistics
Time zones and language: Busan vs Chicago
Busan (Asia/Seoul) and Chicago (America/Chicago) sit 15 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration. Note: Chicago observes daylight saving while Busan doesn't, so the gap shifts by an hour part of the year.
Official: Korean · English: Limited · Local language: Recommended
Less English than Seoul — Korean is needed for most daily interactions outside the university district and tourist beaches. Admin and services assume Korean.
Official: English · English: Native-equivalent · Local language: Not needed
English-native, extremely multicultural. Spanish strong in Pilsen / Little Village; Polish heritage on the north side. English universal.

How this page is calculated
Data sources
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-06-10 (Busan) and 2026-05-28 (Chicago).
- FX rate. 1 USD = 1370.3704 KRW, 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
Data as of . Last reviewed .
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 Busan 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.
