Origin
The surname Ohlert is of German origin, and it can be traced back to the Middle Ages in regions of what is now modern-day Germany. The name is believed to have derived from the Old German word "Ohlert," which referred to a person who worked as an olive oil trader or merchant.
In the 13th century, records show the name Ohlert appearing in various forms, such as Ohlert, Ohlerde, and Ohlerde, in various German regions, including Bavaria and Saxony. These early spellings suggest that the name may have initially been associated with specific towns or villages where olive oil trading was a common occupation.
One of the earliest recorded instances of the name Ohlert can be found in the Codex Diplomaticus Saxoniae Regiae, a collection of historical documents from the Duchy of Saxony, dating back to the 14th century. The document mentions an individual named "Johannes Ohlert" who was a merchant in the city of Leipzig.
Another notable historical figure bearing the surname Ohlert was Hans Ohlert, a German painter and engraver who lived in the 16th century. He was known for his religious-themed artwork and his collaborations with other notable artists of the time, such as Albrecht Dürer.
During the 17th century, the name Ohlert appears to have spread beyond Germany, as records show individuals with this surname living in neighboring regions, such as the Netherlands and Denmark. One notable individual from this era was Pieter Ohlert, a Dutch merchant and trader who was involved in the spice trade with the East Indies.
In the 18th century, the Ohlert name gained prominence in the field of academia, with Johann Georg Ohlert (1718-1789), a German theologian and philosopher who served as a professor at the University of Leipzig. His writings and teachings had a significant influence on the intellectual discourse of his time.
Another notable figure from this period was Carl Friedrich Ohlert (1756-1835), a German composer and music theorist. He was known for his contributions to the development of music education and his compositions for various instruments, including the piano and the violin.
Throughout the 19th century, the Ohlert surname continued to be present in various fields, including science, literature, and politics. One prominent individual was Gustav Ohlert (1831-1901), a German botanist who made significant contributions to the study of plant taxonomy and the classification of plants.
Demographics
Among Census respondents with the surname Ohlert, the largest self-reported group is White at 93.9%. The next largest groups are Asian/Pacific Islander (2.6%) and Two or More Races (2.6%).
The bar chart below shows how Ohlert 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 Ohlert 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.
