How this works

Weeks run Monday–Sunday; months and years follow the UTC calendar. Counts use current topic assignments throughout the archive. Stories can belong to several topics, so area and share represent topic memberships. Unfiled stories are excluded. The map shows only the leading topics and rescales them to fill the canvas. Percentages always refer to all topic memberships. The latest period may be incomplete.
