Origin
The surname KEIM is believed to have originated in Germany, with its earliest recorded use dating back to the 12th century. It is thought to be derived from the Old German word "keim," which means "sprout" or "seed," suggesting that the name may have been initially given to someone who lived near a field or engaged in agricultural activities.
One of the earliest recorded instances of the KEIM surname can be found in the German town of Kaiserslautern, where a certain Johannes Keim was mentioned in a historical document dated 1295. This document, which detailed a land transaction, provides valuable insight into the prevalence of the name in the region during that time.
In the 16th century, the KEIM surname appeared in various other German regions, including Bavaria and Saxony. During this period, the name was sometimes spelled differently, such as "Keim," "Keym," or "Keimb," reflecting the variations in regional dialects and scribal practices.
Throughout the centuries, several notable individuals have borne the KEIM surname. One such figure is Johann Wilhelm Keim (1711-1784), a German theologian and author who served as a professor at the University of Giessen. Another prominent bearer of the name was Johann Georg Keim (1763-1824), a German philosopher and educator who wrote extensively on education and moral philosophy.
In the 19th century, the KEIM surname gained recognition in the United States, likely due to German immigration. One notable American with this surname was John Keim (1811-1891), a businessman and politician from Pennsylvania who served as a member of the United States House of Representatives.
Another individual of note is Johann Keim (1840-1919), a German-born American who became a prominent businessman and philanthropist in Ohio. He founded the successful Keim Milling Company and was known for his charitable contributions to educational institutions and community organizations.
The KEIM surname has also been associated with several places throughout history. For instance, the town of Keim in Rhineland-Palatinate, Germany, is believed to have derived its name from the surname. Additionally, there are several villages and hamlets in Germany with names such as Keimbach and Keimhausen, which may have connections to the KEIM surname.
While the KEIM surname has its roots in Germany, it has since spread to various parts of the world, including the United States, Canada, and other countries with significant German immigration. Throughout its history, the name has been borne by individuals from diverse backgrounds, ranging from scholars and philosophers to businessmen and politicians.
Demographics
Among Census respondents with the surname Keim, the largest self-reported group is White at 94.2%. The next largest groups are Two or More Races (2.3%) and Hispanic (2.2%).
The bar chart below shows how Keim 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 Keim 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.
