Plain-language metrics for the main content of each scanned page (navigation, header, and footer excluded). Download CSV.
What these mean
Words per page
Main-content word count. Median 87
Reading ease (Flesch)
0–100; higher is easier. ~60+ is plain language; below ~30 is very hard. Median 75
Grade level (Flesch-Kincaid)
US school grade needed to read it; aim for ~8 or lower for the public. Median 6
Scored
A reading grade is only meaningful on running prose, so we score a page only when it has enough of it. Pages that are mostly links or cards (too little text) or mostly tables and data (not prose) are left unscored — a grade there would be misleading, no matter how many words they contain. 172 of 483 scored
Heuristics for triage and trends, not authoritative linguistics. They flag pages worth a human plain-language review.
