Origin
The surname Caplan has its origins in the Jewish communities of Eastern Europe, particularly in Russia and Ukraine. It is believed to have derived from the Yiddish word "kaplan," which means "chaplain" or "rabbi's assistant." This suggests that the name was likely first adopted by individuals who served in synagogues or had religious roles within their communities.
The earliest recorded instances of the name Caplan can be traced back to the late 18th century and early 19th century in various census records and official documents from the Russian Empire. During this period, many Jewish families were required to adopt surnames, and Caplan became a popular choice.
One notable historical reference to the name Caplan is found in the memoirs of Nikolai Gogol, the famous Russian writer. In his work "Dead Souls," Gogol mentions a character named Caplan, suggesting that the name was already well-established in Russia by the early 19th century.
As the Jewish population of Eastern Europe migrated westward, the name Caplan spread across Europe and eventually to other parts of the world. Some variations of the spelling include Kaplin, Kaplan, and Caplain, reflecting the diverse linguistic and cultural influences encountered during this migration.
Among the notable individuals with the surname Caplan throughout history are:
1. Abraham Isaac Caplan (1853-1915), a Russian-born American rabbi and scholar who served as the Chief Rabbi of Montreal.
2. Harry Caplan (1896-1979), an American businessman and philanthropist who co-founded the Caplan Corporation, a successful retail chain.
3. Lionel Caplan (1914-2009), a South African-born British actor and playwright known for his roles in films such as "The Ipcress File" and "The Spy Who Came in from the Cold."
4. David Caplan (born 1965), a Canadian politician who served as a member of the Legislative Assembly of Ontario and held various cabinet positions.
5. Ralph Caplan (1915-2019), an American businessman and philanthropist who co-founded the Caplan Corporation with his brother Harry.
While the surname Caplan has its roots in Eastern Europe, it has since become widely dispersed worldwide, with notable bearers contributing to various fields, including religion, business, entertainment, and politics.
Demographics
Among Census respondents with the surname Caplan, the largest self-reported group is White at 92.3%. The next largest groups are Hispanic (3.4%) and Two or More Races (2.6%).
The bar chart below shows how Caplan 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 Caplan 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.
