Who are the Giay?  The Giay people group (pronounced "Zay") is one of Vietnam’s 53 minority groups, with a population of 47,100.  The Giay people, however, are also found in significant numbers outside Vietnam.  More than 250,000 Giay live in southern China, and refugee populations live in France and California, USA. 

Giay is their name for themselves.  Neighboring Tribal peoples call them Giang, while the Vietnamese call them Nhang.  There is one distinct subgroup who go by the name Pu Na.  The 1974 census put the Pu Na total at 1,687, but they have been included with the Giay ever since.  Pu Na means "farming people" in their dialect of the Tai-Thai language. The Giay are also known by a number of other names, to include: Sa Nhan, Pu-Nam, Chung Cha, Xa, Cui Chu and Pau Thin.

They are an unreached people group.
