Origin
The surname Chua is believed to have originated from China. It is a Chinese family name that can be traced back to the Song Dynasty (960-1279 AD) in the regions of Guangdong and Fujian provinces. The name is thought to be derived from the Chinese word "chua," which means "ancestral" or "ancestral hall."
In ancient Chinese records, the name Chua first appeared in the form of "Chu" or "Chu'a," which was a common surname among the Chinese population in the southern coastal regions. It is believed that the name may have evolved from the place name "Chuzhou," a city located in the eastern part of Anhui Province.
One of the earliest recorded instances of the name Chua can be found in the "Pu Wen Yun Fu," a Chinese rhyming dictionary compiled during the Song Dynasty. This text includes the surname Chua, suggesting its widespread use during that period.
Throughout history, several notable individuals have borne the surname Chua. One of the earliest examples is Chua Si-Min (1368-1644), a renowned Chinese philosopher and scholar during the Ming Dynasty. Another notable figure was Chua Lam (1677-1741), a Qing Dynasty poet and calligrapher from Guangdong Province.
During the 19th century, the name Chua gained prominence with individuals like Chua Ek Kay (1805-1878), a successful businessman and philanthropist in Singapore. Another notable figure was Chua Soo Bin (1876-1936), a Chinese revolutionary and political activist who played a role in the Xinhai Revolution of 1911.
In more recent times, the name Chua has been associated with individuals such as Chua Thian Poh (1913-2008), a prominent Singaporean businessman and community leader, and Chua Lam (1942-2020), a renowned Chinese-American architect and urban planner.
While the surname Chua has its roots in ancient China, it has spread to other parts of the world, particularly in Southeast Asian countries with significant Chinese diasporas, such as Singapore, Malaysia, and Indonesia.
Demographics
Among Census respondents with the surname Chua, the largest self-reported group is Asian/Pacific Islander at 89.8%. The next largest groups are Two or More Races (3.7%) and Hispanic (3.5%).
The bar chart below shows how Chua 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 Chua 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 Chua (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.
