region was empty on all 242 country rows, so the map had no way to answer "what share of
this part of the world is unreached" — only how many groups a country holds and how many
people live in them.
The source carries UNm49Region, and it was verified before being trusted: only 2, 9, 19,
142 and 150 appear — exactly the five UN M49 top-level regions — every country maps to
exactly ONE of them with 0 conflicts, and the five sum to 12,379, the whole corpus. So
the code resolves to a real name. It is backfilled on every row, not just the new ones,
and all 242 now carry a region with none blank.
The rate is a genuinely different answer from the two already on offer:
Oceania 51.2% of its 1,325 groups have nothing — 679 groups — 3.1M people
Africa 30.0% of 3,074 — 923 — 68.2M
Asia 19.3% of 5,073 — 978 — 198.7M
Americas 11.4% of 2,117 — 241 — 6.1M
Europe 10.1% of 790 — 80 — 11.6M
Oceania is half unreached by group and the smallest population of the five; Asia is the
reverse on both. Ranked by rate, because count and population are what the other two tabs
already say and a third copy of either would be noise. All three are offered rather than
one picked for the reader.
The rows are plain divs, not buttons: a region is not somewhere this map can fly to, and
a control that looks clickable and does nothing is worse than a row that does not pretend.
Verified against an offline computation over the same index: all five regions match
exactly on rate, group count and population. The sheet header is now three-way rather
than showing the country prose in region mode. All five profiles still mount clean.
