Origin
The surname EIN originated in Germany and can be traced back to the Middle Ages. It is derived from the Old German word "ein," which means "one" or "a single." This surname was likely given to someone who was the only child or the oldest child in a family.
One of the earliest recorded instances of the surname EIN can be found in the Codex Diplomaticus Anhaltinus, a collection of historical documents from the former principality of Anhalt in central Germany, dating back to the 13th century. The name is also mentioned in the Annales Pegavienses, a medieval chronicle from the town of Pegau, Saxony, which dates back to the 14th century.
In the 15th century, the surname EIN appeared in the records of the city of Cologne, where a merchant named Johann Ein is mentioned in a trade document from 1487. Another notable individual with this surname was Hans Ein, a master stonemason who worked on the construction of the Heilig-Geist-Kirche (Church of the Holy Spirit) in Heidelberg in the early 16th century.
One of the earliest known bearers of the surname EIN was Konrad Ein, a Benedictine monk who lived in the Abbey of St. Gall in Switzerland in the late 12th century. He is credited with transcribing several important manuscripts, including works by the Roman philosopher Cicero.
Another significant figure was Philipp Ein, a German jurist and legal scholar who lived in the 16th century. Born in Worms in 1504, he studied law at the University of Heidelberg and later became a professor of law at the University of Ingolstadt. He wrote several influential works on legal theory and practices.
In the 17th century, the surname EIN was also found in the records of the town of Zerbst, in the modern-day state of Saxony-Anhalt, where a family named Ein owned a substantial amount of land and property. One member of this family, Hans Ein, was a respected merchant and served as a town councilor in the mid-1600s.
Demographics
Among Census respondents with the surname Ein, the largest self-reported group is White at 61.0%. The next largest groups are Asian/Pacific Islander (30.0%) and Two or More Races (8.0%).
The bar chart below shows how Ein 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 Ein 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.
