UW–Madison statistics.

Derived from the published dataset, scanned 2026-09-07. Coverage varies by term. Missing records are not treated as zero.

Meetings count once per occupied hour, including partial hours. The map counts recorded enrollment for each scheduled meeting: the same enrollment is counted again when a class meets again. These are enrollment visits, not unique students or actual attendance.

Course identities and section IDs are deduplicated across listings. Lecture totals exclude labs and discussions; building enrollment excludes meetings with unknown enrollment. Grades use the import’s reconciled course/term totals, weighted by letter-grade counts, without adding section totals again. Trends reflect the courses and grades recorded each term, not changes in the same students.

All observations are calculated from the data, not generated by an LLM.
