This page mixes several evidence types, so every benchmark should be read according to where it came from and what is missing. It is not presented as one controlled study with a single methodology.
The source identifies public industry material associated with organizations such as the National Association for the Education of Young Children (NAEYC) and childcare policy groups, search patterns from keyword tools and Google Search Console, and directional observations from early education campaigns. The exact sample and method are not documented for every statement.
The example of a 40-70% January search-volume spike has no supporting source URL in this JSON. Preserve that range only as previously published directional context requiring source reconciliation, not as a verified market-wide statistic.
For the 2026 edition: the source explicitly warns that older digital-behavior benchmarks can age quickly. Figures from 2020 or 2021 should not be assumed current without checking the original primary material or current first-party data.
Use the page for orientation and interpretation. Do not copy a precise figure into external reporting unless its source, period, definition, and methodology have been verified.
