Origin
The surname LAI has its origins in China, where it first emerged during the Tang Dynasty (618-907 AD). The name is derived from the Chinese word "lai," which means "to come" or "to arrive." It is believed that this surname was initially given to individuals who had traveled or immigrated from one region to another.
LAI is a widespread surname found across various regions of China, including Guangdong, Fujian, and Jiangxi provinces. In ancient times, the name was sometimes written with different characters or spellings, such as 赖 or 莱, but the pronunciation remained similar.
One of the earliest recorded instances of the LAI surname can be traced back to the Song Dynasty (960-1279 AD). Historical records mention a scholar named Lai Shengxuan, who lived during the Northern Song period (960-1127 AD) and served as a high-ranking official in the imperial court.
During the Ming Dynasty (1368-1644 AD), a notable figure with the LAI surname was Lai Xingzheng, a celebrated poet and calligrapher. Born in 1502 in Jiangxi Province, Lai Xingzheng's works were highly acclaimed and are still studied by scholars today.
Another prominent individual with the LAI surname was Lai Guanlin, a military strategist and general who lived during the Qing Dynasty (1644-1912 AD). Lai Guanlin played a crucial role in suppressing various uprisings and rebellions, earning him a reputation as a skilled commander.
In the realm of literature, Lai He (1896-1968) was a renowned Chinese writer and translator. He was instrumental in introducing Western literary works to Chinese audiences and is celebrated for his contributions to modern Chinese literature.
Lastly, Lai Fusheng (1901-1993) was a prominent Chinese historian and archaeologist. He made significant discoveries and contributions to the understanding of ancient Chinese history, particularly during the Shang and Zhou dynasties.
While the LAI surname is predominantly found in China, it has also spread to other parts of the world due to immigration and diaspora communities. However, its roots and historical significance remain deeply rooted in Chinese culture and ancestry.
Demographics
Among Census respondents with the surname Lai, the largest self-reported group is Asian/Pacific Islander at 91.6%. The next largest groups are White (3.4%) and Two or More Races (3.2%).
The bar chart below shows how Lai 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 Lai 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 Lai (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.
