- Metric
- Median age
- Scale
- 100 = oldest median age, 0 = youngest — descriptive, not better or worse
- Raw value
- 38.81 years
- Native score
- 54.06 — this metric's own 0–100 scale; not comparable to other metrics.
- Percentile rank
- 72th percentile — ranks 67th of 237. Comparable across metrics.
- Normalization
- Min–max (rescaled against the dataset)
score = 100 · (38.81 − 14.32) / (59.63 − 14.32) = 54.06Min and max are this dataset's lowest (14.32) and highest (59.63) values, so the score is relative to the current country set.
