MacroScore = Σ(pillar_i × weight_i)City and country indicators are normalized to comparable 0-100 pillar scores before weighting.
HumanRank alpha
Public methodology
HumanRank publishes weights, sources, uncertainty and correction requests so the ranking stays debatable, auditable and versioned.
research note
Technical whitepaper
The alpha publishes its operating math so assumptions can be challenged, bias can be audited and weight changes can be proposed. Cohort scoring still uses normalized seed inputs; the production pipeline should replace them with fully lineaged BigQuery observations.
Published formulas
These formulas describe the current macro cohort model. Public figures use a separate sourced editorial model version.
EarthScore = round(clamp(MacroScore + AgeCurve + CohortVariance, 1, 99) × 10)The alpha cohort score is a potential estimate, not an identity-level measurement.
Percentile = logistic((EarthScore - 520) / 125)The logistic curve maps score to a global rank without materializing every living person.
GlobalRank = round((1 - Percentile) × 8,120,000,000)Public figures and anonymous cohorts are interleaved into the same living-population rank space.
Confidence = f(source quality, recency, missingness, geography precision, stability)Confidence controls the published uncertainty band and should rise only with better evidence.
data lineage
Cohort data lineage
Every pillar must be reproducible: source, year, geography, license, transform and missingness policy. This table is the production contract, not a claim that every local datapoint already exists.
transform: Log income transform blended with local quality-of-life signal, then robust percentile normalization.
missingness: Fall back from city to country to region; increase uncertainty when geography is coarse.
transform: Orient life expectancy and burden indicators so higher means better; winsorize extreme tails.
missingness: Use latest comparable year; penalize stale or country-only health data.
transform: Normalize attainment, expected schooling and access indicators inside comparable income/geography bands.
missingness: Missing subnational detail is imputed from country data and reflected in confidence.
transform: Normalize public safety and conflict exposure indicators after orienting lower-risk values upward.
missingness: No private or protected-attribute safety proxy is allowed; missing city data widens uncertainty.
transform: Normalize air, climate and service-quality indicators against comparable urban areas.
missingness: Use country-level planetary-pressure controls only when city indicators are absent.
transform: Normalize internet, transport and service-access indicators; cap outliers from dense global hubs.
missingness: Prefer official local statistics; otherwise use country connectivity with lower confidence.
transform: Blend labor-market, mobility and services indicators after equal-weight and sensitivity checks.
missingness: Do not infer opportunity from wealth alone; unresolved inputs lower confidence.

confidence model
Uncertainty breakdown
Uncertainty is not decoration. It is where the model admits that a macro cohort is not a real person and less precise data should carry less confidence.
Missingness: incomplete city or subnational indicators widen the score interval.Recency: older source years lower confidence until refreshed in BigQuery.Geographic precision: country-level proxies are less precise than city-level observations.Source quality: official and stable sources raise confidence; weak or single-source evidence lowers it.Model stability: scores must be compared against equal-weight and PCA-style baselines before weight changes.
Reproducibility and limits
Every production indicator must carry source, URL, geography, year, license, transform and ingestion timestamp.Every model release must keep its weights, formulas and score distribution snapshot.Named public profiles must show source count, model version, confidence and a correction path.Anonymous population cohorts stay aggregated until a person opts in to claim a profile.HumanRank is not a credit, employment, housing, insurance or government-benefit decision system.
Scientific controls
Protected attributes are not score inputs.Every indicator needs source, geography, year, license, transform and missingness metadata.Scores must publish uncertainty, not just rank.Weights are model-versioned and sensitivity-tested before release.Users can inspect, revoke and challenge personal evidence.Social proof is evidence, never a raw popularity boost.

Production pipeline
- Ingest raw indicators from official or methodologically documented sources into BigQuery.
- Normalize each indicator with robust percentiles or z-scores inside comparable geographies.
- Winsorize extreme values, orient all indicators so higher means better, and record the transform.
- Compute pillar scores with versioned weights and compare against equal-weight and PCA baselines.
- Publish confidence from source quality, recency, missingness, geographic precision and model stability.
- Run fairness audits on aggregate opt-in groups without using those attributes in scoring.
