In all the world, Тхаи (Thai 
, Tkhai 
, Txai 
) is a common predominantly masculine, but very infrequently feminine given name. The first name Тхаи is habitual in Macao, where it is quite a common unisex name, Vietnam, where it is quite a common principally male, but scarcely female name, and Saudi Arabia, where it is quite a rare largely male, but uncommonly feminine name. Not in comparison with a country's population, it is the most numerous in Vietnam, the United States, and Saudi Arabia. Also, Тхаи is the last name as well as the forename.
