Around the globe, ทอ. (Tho 
, ทอ. 
) is a common dominantly masculine, but infrequently female first name. The given name ทอ. is habitual in Macao, where it is quite a common girly name, Vietnam, where it is quite a rare largely male, but uncommonly female name, and the Democratic Republic of the Congo, where it is a rare male name. Not in comparison with a country's population, it most frequently occurs in South-eastern Asia, particularly Vietnam, Indonesia, and Philippines. Likewise, ทอ. is the last name as well as the forename.
