Origin
The surname Kagan has its origins in the Turkish and Mongolian languages, tracing back to the Khagan title used by the rulers of nomadic Turkic and Mongolian tribes in Central Asia during the medieval period. The word "Khagan" is derived from the Old Turkic "Kağan" or "Qaghan," meaning "Khan of Khans" or "Great Khan."
The Kagan surname is believed to have emerged among Ashkenazi Jewish communities in Eastern Europe, particularly in Poland, Ukraine, and Russia, where Jewish families often adopted surnames based on their occupations, locations, or personal characteristics. It is possible that the name Kagan was initially adopted by individuals or families with connections to the Khagan title or Central Asian regions.
Historical records indicate that the Kagan surname appears in various manuscripts and documents from the 16th century onwards. One notable example is the mention of the Kagan family in the Metrical Register of the Kahal Kadosh of Lublin, Poland, dated 1564-1569.
Among the earliest recorded individuals with the Kagan surname is Yehuda Leib Kagan, a prominent Talmudic scholar and author who lived in the late 18th century in Vilna, Lithuania. Another notable figure is David Kagan, a 19th-century Hebrew writer and poet from Galicia, a historical region spanning parts of modern-day Poland and Ukraine.
Throughout history, several individuals with the Kagan surname have made significant contributions in various fields. These include:
1. Yisroel Meir Kagan (1838-1933), also known as the Chofetz Chaim, a renowned Talmudic scholar and author from Belarus.
2. Joseph Kagan (1858-1937), a Russian-American banker and philanthropist who helped establish the Hebrew University of Jerusalem.
3. Solomon Kagan (1858-1925), a prominent Zionist leader and writer from Lithuania.
4. Velvel Kagan (1885-1971), a Yiddish writer and educator from Ukraine.
5. Matvey Petrovich Kagan (1888-1937), a Soviet physicist and professor at Moscow State University.
The surname Kagan has also been associated with various place names and locations, such as the town of Kaganovichi in Belarus, which may have derived its name from the Kagan surname.
Demographics
Among Census respondents with the surname Kagan, the largest self-reported group is White at 93.3%. The next largest groups are Hispanic (2.8%) and Two or More Races (2.0%).
The bar chart below shows how Kagan 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 Kagan 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 Kagan (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.
