Registration: one boy enrolled in one season. A returning boy is counted again in each season he participates.

Verified scope: 23 standard Spring/Fall seasons from Spring 2014 through Spring 2026.

Source: the Pinwheel all-regions-active historical participant export from Spring 2014. 2009–2013 come from the hand-typed growth spreadsheet; where the two overlap, Pinwheel is used.

Excluded records: 31 waiver-event rows, two Summer 2025 records, and eight Spring 2026 program-template rows are not participant seasons. Fall 2026 is shown as in progress, from the latest daily refresh.

Regional figures: current five-region mapping, reconciled to the participant records included in the report.

Intentionally not shown: financial-assistance totals and trend conclusions. Their definitions and source fields changed across seasons, so this draft does not treat them as historically comparable.
