Origin
The surname SCHLAMAN has its origins in Germany, tracing back to the late 16th century. It is believed to have originated from the Low German word 'schlamm', which translates to 'mud' or 'sludge', possibly indicating that the name was initially associated with individuals who lived near or worked in muddy areas or marshlands.
One of the earliest recorded instances of the name SCHLAMAN can be found in the parish records of the town of Gartow, located in present-day Lower Saxony, Germany, where a certain Johann SCHLAMAN was listed as a resident in 1598. This suggests that the name was already in use and somewhat established in that region during the late Renaissance period.
During the 17th and 18th centuries, the SCHLAMAN surname began to spread across various parts of northern Germany, particularly in the areas around the cities of Hamburg and Bremen. It is plausible that the name was also influenced by or derived from local place names containing similar root words, such as the village of Schlamau in Saxony-Anhalt or the town of Schlamersdorf in Mecklenburg-Vorpommern.
Notable individuals bearing the SCHLAMAN surname throughout history include Johann SCHLAMAN (1675-1743), a prominent merchant and landowner in the city of Lüneburg, and Heinrich SCHLAMAN (1798-1872), a respected Lutheran theologian and author from Hanover. Other notable SCHLAMANS include Wilhelm SCHLAMAN (1842-1912), a German-American inventor and industrialist who made significant contributions to the development of early refrigeration technologies, and Gertrud SCHLAMAN (1909-1986), a renowned German opera singer who performed extensively throughout Europe in the mid-20th century.
The SCHLAMAN name also found its way into historical records and documents in other parts of Europe, such as the Netherlands and Scandinavia, likely due to migration patterns and trade connections. For instance, there are records of a Jacob SCHLAMAN being a merchant in Amsterdam in the late 17th century, while a family by the name of SCHLAMAN is documented as having settled in the Swedish province of Skåne in the early 1800s.
Demographics
Among Census respondents with the surname Schlaman, the largest self-reported group is White at 90.9%. The next largest groups are Two or More Races (4.0%) and Black (3.0%).
The bar chart below shows how Schlaman 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 Schlaman 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.
