Methodology

Figures are hand-curated from public health authorities and peer-reviewed publications. Each is a point-in-time snapshot; the date shown is the year the source was published or the period it covers. Where a source publishes updated figures, the most recent available at the time of review is used.

This journey supports clarity, identity, and design thinking. It is not a substitute for professional mental health care.
