Every book & reading number, sourced.
What Book Statistics is
Book Statistics is the reference layer of Figures Bureau, a data-publications studio. It publishes computed, source-verified book and reading numbers in lookup form — tables, definitions, per-year figures — built from an original dataset of 13,258 state reading-list assignments, each row carrying its own source URL and verification date.
Every figure is recomputed from the underlying dataset on every build. Numbers we cannot verify are omitted, never guessed — the methodology explains exactly how each statistic is computed and where the data comes from.
The reference library
- Most-assigned books, ranked The living top-50 table: which books U.S. reading lists assign most, with counts, states and grade bands.
- Assigned books statistics The whole corpus in reference form — top books and authors, grade-band split, publication eras, coverage and provenance.
- School reading list statistics How many states publish lists, how big they run, which grades they target, and how many sources back the data.
- Book length statistics Median assigned-book length for every grade K–12 — including the 3rd-grade cliff.
- Assigned book age statistics Publication years of the assigned canon, decade by decade — the dusty-classics story, tested.
- Reading statistics How many Americans read and how much — primary sources only, each dated and linked, anchored by the assigned-books corpus.
- Bestseller statistics The real odds of making the NYT bestseller list — copies needed, seasonality, and how fast books fall off.
