Origin
The surname "Ha" is believed to have originated in Vietnam, where it has been a common family name for centuries. Some linguists trace its roots to the ancient Vietnamese word "ha," which translates to "river" or "stream." This connection suggests that the name may have initially referred to individuals who lived near bodies of water.
In the 15th century, the name "Ha" appeared in several historical records, including the Annals of Dai Viet, a chronicle detailing the history of Vietnam during the Le Dynasty. One notable figure from this era was Ha Nhu An (1415-1496), a celebrated poet and scholar who served as a royal advisor to multiple Vietnamese emperors.
During the 17th and 18th centuries, the name "Ha" proliferated across various regions of Vietnam, particularly in the northern provinces. One prominent individual from this period was Ha Trung Hieu (1693-1765), a revered Confucian scholar and philosopher who made significant contributions to Vietnamese literature and education.
The 19th century saw the rise of several influential figures bearing the "Ha" surname. Among them was Ha Huy Tap (1828-1908), a renowned poet and calligrapher who played a pivotal role in preserving and promoting Vietnamese traditional arts and culture.
In more recent history, Ha Xuan Trung (1892-1979) was a prominent Vietnamese politician and diplomat who served as the first ambassador of the Republic of Vietnam to the United States.
Another notable figure was Ha Thi Que (1918-2003), a celebrated writer and revolutionary who played a crucial role in the Vietnamese independence movement against French colonial rule.
While the surname "Ha" has its roots in Vietnam, it has also been adopted by individuals of Vietnamese descent living in various parts of the world, including the United States, Canada, and several European countries.
Demographics
Among Census respondents with the surname Ha, the largest self-reported group is Asian/Pacific Islander at 93.7%. The next largest groups are White (2.6%) and Two or More Races (2.0%).
The bar chart below shows how Ha bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Ha surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Ha (2000, 2010, 2020).
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
