New tracker entries per month

This is the latest saved tracker snapshot by first-report month, including all statuses. The composite uses rolling 12-month totals. Later tracker additions affect future Index months and leave published scores frozen. Research and press coverage affect what we find. They do not count everyone leaving Britain.

People and companies with a known report month. Empty months mean zero entries. Year-only reports are excluded.
