"How many countries does Natural Earth have" is scale-dependent. Both files sentinel `ISO_A2 = "-99"` (and the matching `ISO_A3`/`ISO_N3` = `"-99"`) for countries Natural Earth treats as not cleanly ISO-coded: **France and Norway** (because of how NE splits their metropolitan vs. full-sovereignty geometry), plus **Kosovo, Northern Cyprus and Somaliland** (contested/unrecognized statehood). `ADM0_A3` carries a real, non-sentinel code for all five (`FRA`, `NOR`, `KOS`, `CYN`, `SOM`) — a join keyed on `ISO_A2`/`ISO_A3` silently drops these five countries (eight at 50m, which adds `Indian Ocean Ter.`, `Ashmore and Cartier Is.`, `Siachen Glacier`) while a join keyed on `ADM0_A3` keeps them.
