| jurisdiction Italy | 3 year (one figure) | one figure, no range | 1 |
Every figure, with its source
One row per published figure: the figure as the source's own page publishes it, the page, and the day it was read. A figure that is not on a page we read is not on this one.

Methodology
Every row is a verbatim sentence read from the named source's own page through our fetch service on the date shown, hash-pinned to the stored read (the sha of the page's visible text; the raw page is mirrored to R2).
2 of the 21 named sources that could be read published a usable figure; 19 published none and are recorded as not published, never filled in; 4 could not be read (blocked, dead or unreachable) and count nowhere.
The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source in year (a source's median where its page yielded several accepted sentences), so N counts sources, never sentences; 65 candidate sentence(s) were refused by a reviewer with the reason recorded.
The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): one row per jurisdiction per rule - generation depth, the cut-off date or event, whether the intermediate generation had to register, language or residence conditions, whether dual nationality is kept - each read from that country's own nationality authority; the comparison ACROSS all of them (how many countries reach a great-grandparent, which cut-offs fall in which decade, which regimes narrowed in the last two years) is the figure nobody publishes with sources; changed-since on every read, which is the news when a nationality act is amended
65 candidate sentences on these pages were refused by a reviewer; each refusal and its reason is recorded in the review ledger.
