According to the 2009 census, the dominant Viet or Kinh ethnic group constituted nearly 73.6 million people, or 85.8% of the population.
The Kinh population is concentrated mainly in the alluvial deltas and coastal plains of the country.
A largely homogeneous social and ethnic group, the Kinh possess significant political and economic influence over the country.
However, Vietnam is also home to 54 ethnic minority groups, including the Hmong, Dao, Tay, Thai, and Nùng.
Many ethnic minorities – such as the Muong, who are closely related to the Kinh – dwell in the highlands, which cover two-thirds of Vietnam's territory.
Before the Vietnam War, the population of the Central Highlands was almost exclusively Degar (including over 40 tribal groups); however, Ngô Đình Diệm's South Vietnamese government enacted a program of resettling Kinh in indigenous areas.
The Hoa (ethnic Chinese) and Khmer Krom people are mainly lowlanders.
As Sino-Vietnamese relations soured in 1978 and 1979, some 450,000 Hoa left Vietnam.
There are three ethnic groups living in the district, Kinh, Cham people and BaNa.
The Cham are mainly concentrated mainly in Canh Hoà, Bana ethnic concentration in Canh Liên, Canh Thuận, Canh Hiệp, where they exceed 40% of the total population.
The Cham people settled in the mountainous area along with the indigenous tribes after the kingdom of Champa was dismantled in 1471.
As a result, the Cham have adopted many facets of Bana culture.
