Origin
The surname SIDERS is believed to have originated in Germany during the 16th century. It is thought to have derived from the Old German word "sider", which referred to a person who lived near a body of water or who worked on a river or lake.
The earliest known record of the SIDERS name dates back to 1523, when a Johannes Siders was mentioned in a church registry in the city of Cologne. It is possible that this individual or his ancestors had migrated from a nearby town or village with a name related to water or a river.
In the 17th century, the SIDERS name began to appear in various records across Germany, particularly in the regions along the Rhine River and its tributaries. Some variations in spelling included Syderes, Siederss, and Siderius.
One notable SIDERS from this era was Hans Siders, a merchant and ship owner from the city of Mainz, who lived from 1620 to 1687. He was known for his successful trading ventures along the Rhine and his involvement in local politics.
As the SIDERS family continued to spread throughout Germany and beyond, the name also found its way into other parts of Europe. In the 18th century, a branch of the family settled in the Netherlands, where the name was sometimes spelled as Sijders or Sijderes.
One of the most famous individuals with the SIDERS surname was the German philosopher and theologian Friedrich Wilhelm Josef Siders, who lived from 1786 to 1859. He was a prominent figure in the German Idealist movement and authored several influential works on metaphysics and ethics.
Another notable SIDERS was the Dutch painter Johannes Siders, born in 1812 in Amsterdam. He was known for his landscape paintings and is considered one of the leading figures of the Hague School of painting in the 19th century.
As the SIDERS name continued to spread across Europe and eventually to other parts of the world, it underwent various spelling variations and adaptations based on local languages and customs. However, its origins can be traced back to the waterways and rivers of Germany in the 16th century.
Demographics
Among Census respondents with the surname Siders, the largest self-reported group is White at 82.2%. The next largest groups are Black (9.3%) and Two or More Races (4.2%).
The bar chart below shows how Siders 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 Siders 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.
