Data Methodology
WhereNext algorithmically scores and ranks 95 countries across 7 dimensions using institutional public-domain datasets, reducing subjective bias in your relocation decisions.
Quick answer
The WhereNext composite score scores 95 countries on a 0–100 scale across 7 quality-of-life dimensions: cost (affordability), safety, healthcare, education, career, lifestyle, and infrastructure. Each dimension blends API-fetched institutional data (World Bank Indicators, WHO, Open-Meteo) with curated indices (UNDP HDI, IEP Global Peace Index, OECD PISA, EF EPI). Costs are PPP-adjusted using GDP-PPP ratios. Confidence scores reflect actual data availability per country. Users can re-weight the 7 dimensions to match individual priorities — same data, different rankings for different people. Visa feasibility is a separate post-score adjustment, not bundled into the composite.
Key facts
- 7 normalised dimensions cost, safety, healthcare, education, career, lifestyle, infrastructure — all 0–100 scale, higher = better.
- Data sources World Bank Indicators, WHO, Open-Meteo (live API, 12h cache); UNDP HDI, IEP GPI, OECD PISA, EF EPI (quarterly snapshots).
- User-weighted determinism priority sliders re-weight the 7 dimensions; the same dataset produces different rankings per user.
- PPP adjustment: 30% cost dimension blends nominal prices with GDP-PPP-ratio adjustments to reflect real purchasing power.
- Tiered degradation + confidence scores real data preferred; proxies blended where direct data is missing; transparency on which countries lean on proxies.
TL;DR
- • 7 dimensions (Cost, Safety, Healthcare, Education, Career, Lifestyle, Infrastructure) scored 0–100 using institutional public-domain datasets.
- • Your priority sliders weight the dimensions. Same data, different rankings for different people.
- • Data from World Bank, WHO, Open-Meteo, and others. API responses cached 12 hours; static indices updated quarterly. Confidence scores reflect data availability.
- • Visa adjustment: boost for matched pathways, penalty for difficult immigration.
- • Evidence-based methodology: scores are algorithmically derived from public institutional data, with heuristic models and proxy estimates where direct data is unavailable.
Core Principles
- Data Sourcing: Scoring combines API calls (World Bank, WHO, Open-Meteo) cached 12 hours with curated indices (HDI, GPI, PISA) updated quarterly to annually. This ensures metrics reflect current objective trends, not outdated anecdotes.
- Normalization (0-100): Disparate metrics (GDP, temperature, homicide rates, PM2.5 levels) are harmonized to a 0-100 scale. Higher always means "better" according to standard quality-of-life frameworks.
- User-Weighted Determinism: Your ranking dynamically shifts based on the priority weights you set on the Find page. The same data produces different rankings for different people.
- Tiered Degradation: When real data is available, we use it. When partial data exists, we blend it with proxies. Confidence scores reflect how much real data backs each score.

Confidence Scoring
Each country receives a dynamic confidence score reflecting how much real data backs its ranking. Confidence is domain-aware — it scales with the number of live data domains available, not just individual indicators.
Domain Coverage (5 domains checked)
Base Confidence
Scales from 45% (no domains) to 72% (all 5 domains). Additional indicator bonuses (education, career, air quality, broadband, HDI) add up to +18%.
Hard Caps
Maximum confidence is 92% with 3+ domains. Countries with fewer than 3 live domains are capped at 75% regardless of indicator bonuses.
Visa Feasibility
Rankings are adjusted by visa accessibility. If a country offers a visa pathway that matches your profile (e.g., digital nomad visa for remote workers), it receives a +15% boost. Countries without matching pathways receive a -10% adjustment.
Fallback Handling & Architecture
Every request passes through a central Orchestrator which parallelizes API requests with an 8-second timeout SLA. All responses are cached via Next.js for 12 hours.
If an upstream API goes offline, the DomainResolution fallback logic applies neutral proxy metrics and reduces the confidence score rather than crashing the interface.
Sensitivity Analysis
After ranking, WhereNext automatically perturbs your top 3 weight dimensions by +/-20% to test ranking stability. If a small change in priorities would reshuffle the top results, you'll see a sensitivity warning so you can investigate further before making a decision.
