In this study, linguistic maps of Kra-Dai numerals from 1 to 10,000 are presented. As Benedict reported earlier, forms of Kra and Li are identical to the Austronesian form, while other branches originate from Chinese loanwords. The geographical distribution of the Kra form is observed in the central area of Kra-Dai; however, it shows older characteristics. This is a counter example of the principle of "peripheral distribution" in geolinguistics. Although the geographical distribution of each item follows the general tendency, differences are observed in terms of details of the geographical distribution and diachronic formation process.
