Demographic features of the population of Vietnam include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population. The Viet people (officially Kinh in Vietnam) mostly live in the lowlands and speak Vietnamese, while other ethnic groups speak other languages; together, these communities contribute to the country's demographic composition. Originated from northern Vietnam, the Viets gradually settled southward between 1471 to 1832, displacing native Chams and Khmer Krom.
Vietnam's population reached over 100 million in 2023, making it the 15th largest country by population in the world. It is predicted that by 2035, Vietnam will become an aged society.

The Vietnamese government recognizes 54 ethnic groups, of which the Viet (Kinh) is the largest; according to official Vietnamese figures (2019 census), which account for 85.3% of the country's population and the non-Viet ethnic groups account for the remaining portion.
The relation between China and Vietnam declined following reunification in 1976, with Vietnam siding with the Soviet Union against China in the Sino-Soviet split. In 1978âÂÂ79, some 450,000 ethnic Chinese left Vietnam by boat as refugees (some officially encouraged and assisted) or were expelled across the land border with China. The government has performed an about turn and is encouraging overseas Hoa to return and invest, while the ethnic Chinese population has been in decline since the 1970s due to assimilation and lower birth rates.
The central highland peoples, termed Degar or Montagnards (mountain people), comprise two main ethnolinguistic groups â Malayo-Polynesian and MonâÂÂKhmer. About 30 groups of cultures and dialects are spread over the highland territory.
Other minority groups include the ChamâÂÂremnants of the Champa Kingdom, conquered by the Viet in the 15th century, Hmong, and Thái.
Vietnamese is the national language. It belongs to the Austroasiatic language family, which also includes languages such as Khmer and Mon. Vietnamese was spoken by 85âÂÂ90 million people in Vietnam at the 1999 census. Vietnamese is a tonal, monosyllabic language. Vietnamese was influenced by Chinese, with up to around 50âÂÂ70% words having Chinese origins. Since the 20th century, the Vietnamese have used a Romanized script introduced by the French, developed by Jesuit missionaries led by Alexandre de Rhodes and later on, refined by Vietnamese scholars to produce what is later known as the Vietnamese alphabet.
According to the 2019 Census, the religious demographics of Vietnam are as follows:
It is noted here that the data is skewed, as a majority of Vietnamese may declare themselves atheist yet practice forms of traditional folk religion or Mahayana Buddhism.
