They are
All equally close. Glottolog’s classification is a nesting without branch lengths, so this list cannot be ordered by how closely related its members are.
Measured between recorded points, not between speaker areas. Glottolog’s coordinate is frequently the midpoint of a dispersed population, so this is an order of magnitude rather than a survey.
Computed only among the 726 languages mapped here. A language whose family mostly lives outside Indonesia may have a nearer relative off this map.

- Glottolog’s permanent identifier for this language. Names change, and one name can mean several languages; the code does neither. This whole map is keyed on codes, never on names.
- ISO 639-3

- Endangerment status
- moribund
- Glottolog’s AES assessment: an expert judgement of how far speakers have shifted to another language — not a measurement, not a census, and not a speaker count.

No speaker count is given. Glottolog carries no reliable figures and proprietary sources are not used. An unsourced number is worse than an absent one.
