Origin
The surname "MOK" has its origins in the Netherlands, with records dating back to the 16th century. It is believed to have derived from the Dutch word "mok," meaning a mug or cup, suggesting that the name may have been initially used as a descriptive name for someone who worked with or sold mugs or cups.
The earliest recorded instances of the name "MOK" can be found in Dutch municipal records from the late 1500s, particularly in the provinces of North Holland and South Holland. Some of the earliest documented individuals with this surname include Pieter Mok, born in Amsterdam in 1572, and Jan Mok, a merchant from Rotterdam who lived in the early 17th century.
In the 17th and 18th centuries, the name "MOK" appeared in various Dutch records, including church registers, tax rolls, and legal documents. Several notable individuals with this surname emerged during this period, such as Hendrick Mok (1645-1718), a renowned painter from Delft known for his still-life paintings featuring mugs and cups.
As Dutch settlers and immigrants began to spread across the globe, the surname "MOK" traveled with them. In the late 18th century, records show individuals with this surname in the Dutch East Indies (present-day Indonesia), where they were involved in the spice trade and colonial administration. One such individual was Pieter Mok (1765-1832), a prominent merchant and landowner in Batavia (now Jakarta).
The 19th century saw the further spread of the "MOK" surname, with individuals bearing this name appearing in records from South Africa, where Dutch settlers had established colonies. One notable figure from this period was Johannes Mok (1812-1885), a Boer farmer and military leader who played a role in the Great Trek and the establishment of the Transvaal Republic.
In the 20th century, the "MOK" surname continued to be found in various parts of the world, particularly in countries with Dutch heritage or ties to the Netherlands. Some notable individuals with this surname include Piet Mok (1911-1998), a Dutch painter and sculptor known for his abstract expressionist works, and Theo Mok (1942-2018), a Dutch businessman and philanthropist who founded the Mok Foundation to support education and healthcare initiatives.
Demographics
Among Census respondents with the surname Mok, the largest self-reported group is Asian/Pacific Islander at 88.0%. The next largest groups are White (6.0%) and Two or More Races (3.9%).
The bar chart below shows how Mok 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 Mok surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
