Meaning and origin of Reider
The surname Reider has its origins in Germany and dates back to the 12th century. The name is derived from the German word "Reiter," which means "rider" or "horseman." It is believed that the name was initially given as a descriptive nickname to someone who was a skilled horseman or someone whose occupation involved riding horses.
The earliest recorded instances of the name Reider can be found in various medieval German records and documents. One notable example is the Codex Traditionum Lunaelacensium, a 12th-century manuscript from the Benedictine abbey of Lüneburg, which mentions a person named Reider von Wulfingen.

As the name spread across Europe, it took on various spellings and adaptations. In the Netherlands, the name became Reijder or Reyder, while in France, it was sometimes written as Reidre or Reideur.
One of the most famous individuals with the surname Reider was Christoph Reider (1532-1591), a German Renaissance humanist, poet, and scholar who served as a professor at the University of Heidelberg.

The bar chart below shows how Reider 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 Reider surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Reider (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
