List of municipalities in Thailand

Due to the outdated nature of the thesaban system, any city municipality's growth subsequent to its settlement designation is not included in both area and population numbers.

For this reason, the Department of Public Works and Town & Country Planning,[2] and each province's Provincial Administrative Organization regularly revise and publish up-to-date city boundaries (Thai: เขตเมือง) to reflect population growth.

Neither of the two offices release municipal level figures that include non-permanent residents, long-stay expatriates and figures for contracted foreign ASEAN migrants (a significant labor segment in cities like Bangkok, Pattaya, Chiang Mai, and Phuket, totaling two to three million workers), though this inclusion is being increasingly regularized since 2014.

The NSO did release projected figures including regularized ASEAN migrants, i.e., "total resident population" down to the provincial level for 2017.

In most cases, municipal population numbers do not represent the current size of each individual city, but only the administrative core.
