In depth: why 163,167 becomes 12,074

the raw total, unpacked
The NAR feed re-encodes French place names between releases, so a single accent repair (e.g. Montréal → Montréal) registers as a “city change.” We treat those as noise and count only boundary shifts and genuine renames.

Technical / normalization — excluded

Substantive — counted
