One of the difficulties in interpreting Tasmanian data is the fact that some of the 35 word lists mix data from various locations, and even for the rest, in some cases the location is not recorded. Bowern (2012) used a clustering algorithm to identify language admixture, and further techniques to conclude that the 26 unmixed lists with more than 100 words record twelve Tasmanian varieties (at p < 0.15) that may be assumed to be distinct languages. Due to the poor attestation, these varieties have no names apart from the names of the wordlists they are recorded in. They fall into five clusters; Bayesian phylogenetic methods demonstrate that two of these are clearly related, but that the others cannot be related to each other (that is, they are separate language families) based on existing evidence. Given the length of human habitation on Tasmania, it should not be expected for the languages to be demonstrably related to each other. The families, and the number of attested languages, are:
