National income

Is Arequipa richer than Busan?

The two sit on different measures, so we are not ranking them: Peru is reported as income per capita (GNI, PPP) ($16,780), South Korea as average annual wage ($50,947). A full-time wage and a whole-population income per head are not the same quantity.

Country-level figures — Arequipa is not Peru and Busan is not South Korea, and both cities typically pay above their national average. Gross, before tax: see take-home pay by country for what lands in the account.

Arequipa

High-desert (2,335m) — 300+ sunny days a year, warm days, cold nights, almost no rain outside a brief Jan-Feb wet spell. One of the steadiest climates anywhere.

Busan

Humid subtropical coastal — milder winters than Seoul, humid summers with a wet typhoon-influenced Jul-Sep. The beach city of Korea.

Analyst take

Busan's 6.6 rating edges Arequipa's 6.0 by a narrow margin, suggesting both cities offer comparable livability despite vastly different geographies and development stages.

The 0.6-point gap is smaller than the difference between either city and true outliers, positioning them as peer alternatives rather than obvious winners.

What to do

If choosing between these two, weight your decision on climate preference and job market fit rather than overall score—the numbers suggest quality-of-life trade-offs matter more than raw ranking.

Data signals

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

8.9excellent
  • Cost-of-living index (weight 60%)13
  • Rent index (weight 40%)7
How this is calculated

Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Arequipa: ((100 − 13)/100 × 0.6 + (100 − 7)/100 × 0.4) × 10 = 8.9.

Arequipa sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.

Arequipa has a mixed quality profile. Safety: fair; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.

Arequipa works for remote work but isn't optimized for it: internet 70 Mbps, income tax 12%, cost index 13.

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.

Remote work logistics

Time zones and language: Arequipa vs Busan

Arequipa (America/Lima) and Busan (Asia/Seoul) sit 14 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration.

Arequipa

Official: Spanish · English: Limited · Local language: Required

Spanish required — smaller expat infrastructure than Lima. English is confined to tourism around the historic center.

Busan

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.

Methodology

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 (Arequipa) and 2026-06-10 (Busan).
  • FX rate. 1 KRW = 0.0026 PEN, 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 Arequipa 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.
