This is a population-level study. Its data informs the age windows and confidence scores behind our milestone predictions — telling us when most children reach a given milestone, and how much variation exists.

How we used it

P171 Wave 1 source (scoped 2026-06-03) — ~1,000 routine-tagged activities planned for ingest to fill beta sparse-slot content gap (sleep/care/bath/peer_time/feed at problem ages currently fall through to CATEGORY_EXAMPLES). Activities are slot-tagged + age-tagged natively, anchored to 5 brain-building principles (look/follow/chat/take turns/stretch). Will be mapped at point of ingest per P171 mandatory cascade (EYFS → Stanford → cultural → LC Curriculum → LC Milestone authoring fallback).
