Origin
The surname EINKAUF is of German origin, originating in the medieval period. It is derived from the German words "ein" meaning "one" and "kauf" meaning "purchase" or "trade." The name likely referred to an individual who was involved in trade or commerce, perhaps a merchant or trader.
In its earliest recorded form, the surname was spelled "Einkaufer" or "Eynkaufer," reflecting the linguistic evolution of the German language over time. The earliest known records of the surname date back to the 13th century, appearing in various municipal records and tax rolls from towns and cities across central and southern Germany.
One notable historical reference to the EINKAUF surname can be found in the Stadtbuch (city book) of Nuremberg, which dates back to the 15th century. The book mentions a certain Hans Einkauf, a merchant who was involved in the local guild system and traded in textiles.
Another significant figure bearing the EINKAUF surname was Johann Einkauf, a 16th-century scholar and theologian from Saxony. He was born in 1513 and is known for his contributions to the Protestant Reformation, having worked closely with Martin Luther and other reformers of the time.
In the 17th century, the EINKAUF surname can be traced to the town of Freiburg im Breisgau, where a family of winemakers and vintners with the surname resided. One notable member of this family was Konrad Einkauf, born in 1642, who was renowned for his expertise in viticulture and the production of fine wines.
Another prominent individual with the EINKAUF surname was Friedrich Einkauf, a 19th-century German politician and lawyer. Born in 1815 in Hanover, he served as a member of the Prussian House of Representatives and was a vocal advocate for civil rights and constitutional reforms.
One of the earliest recorded instances of the EINKAUF surname in the New World can be found in the immigration records of Pennsylvania, where a family from Hesse-Darmstadt settled in the late 18th century. This branch of the EINKAUF family played a significant role in the early development of the German-American community in the region.
Demographics
Among Census respondents with the surname Einkauf, the largest self-reported group is White at 90.4%. The next largest groups are Two or More Races (5.8%) and Black (2.9%).
The bar chart below shows how Einkauf 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 Einkauf 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.
