Origin
The surname SCHWEMER is of German origin, originating in the 14th century from the region of Westphalia, in what is now North Rhine-Westphalia. The name is derived from the Middle Low German word "schwēmen," which means "to roam" or "to wander." This suggests that the name may have been given to someone who traveled frequently or had a nomadic lifestyle.
One of the earliest recorded instances of the name SCHWEMER can be found in the Wupper Valley near Solingen, where a document from the year 1385 mentions a "Henrich Schwemer." In the 16th century, the name appeared in various spellings, such as "Schwehmer," "Schwemmer," and "Schwämer," reflecting the regional dialects and variations in pronunciation.
The SCHWEMER name is also associated with the town of Schwelm, located in the Ennepe-Ruhr district of North Rhine-Westphalia. It is possible that the name may have originated from this place name, although the exact connection remains uncertain.

Demographics
Among Census respondents with the surname Schwemer, the largest self-reported group is White at 94.2%. The next largest groups are Asian/Pacific Islander (2.5%) and Two or More Races (2.5%).
The bar chart below shows how Schwemer 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 Schwemer 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.
