🔗 Data Correlations — integrated · exploratory

⚠ Read first — this is for exploration, not signals. Correlation ≠ causation. With 9 indicators there are 36 pairs, so some strong-looking correlations appear by chance (multiple-testing). Many are driven by a hidden common factor (e.g. a country's overall development level). Treat every relationship below as a question to investigate, never as a trading signal or advice. Uses Spearman rank correlation (robust to outliers/skew); ρ ∈ [−1, +1]; n = countries with both values.
