Kaimbulawa is spoken in three villages: Kaimbulawa and Lantoi on the southeastern coast of Siompu Island and, just across a small strait, in Kambekambero village on the southwestern coast of Buton Island. See the sketch map in Van den Berg (1991:51) for the location of these villages.
In terms of its word stock, the variety spoken in Kambekambero village shares similarities with both the Busoa language to its north (84% similar in basic vocabulary) and with Kaimbulawa to its west (80% to 82% similar in basic vocabulary), but Van den Berg grouped it as a dialect of the latter based on shared innovations (1991:45).
Andersen (2006:8) estimates 2,200 speakers of Kaimbulawa. This total omits speakers residing in Kambekambero village.
