Origin
The surname RIENECKER is of German origin, originating in the late medieval period. It is believed to be derived from the German word "Ried," which means a grassy or marshy area, combined with the suffix "-ecker," indicating someone who lived near or worked on such a terrain. This suggests that the name initially referred to individuals residing or employed in marshy regions.
One of the earliest recorded instances of the RIENECKER name dates back to the 15th century in a manuscript from the town of Nürnberg, where a certain Johannes Rienecker was mentioned as a landowner. Another early reference can be found in the church records of the village of Kirchheim, where a family with the surname RIENECKER was documented in the late 16th century.
During the 17th and 18th centuries, the name appears to have spread across various regions of Germany, particularly in the states of Bavaria and Baden-Württemberg. Notable individuals bearing the RIENECKER surname from this period include Johann Georg Rienecker (1622-1688), a Lutheran theologian and author from Saxony, and Anna Maria Rienecker (1738-1805), a renowned painter from Augsburg.
As the centuries progressed, the RIENECKER name continued to be found in various German records and documents. In the 19th century, Friedrich Rienecker (1809-1878), a prominent architect from Stuttgart, gained recognition for his work on several iconic buildings in the city.
Another notable figure was Gustav Rienecker (1883-1963), a German pastor and theologian who authored the influential "Rienecker Lexikon zur Bibel," a comprehensive biblical reference work widely used in German-speaking regions.
In more recent times, one of the most renowned individuals with the RIENECKER surname was Fritz Rienecker (1897-1965), a German theologian and New Testament scholar. His work, "Sprachlicher Schlüssel zum Griechischen Neuen Testament," published in 1952, remains a valuable resource for biblical scholars and students of the Greek language.
While the RIENECKER name has its roots in Germany, it has since spread to other parts of the world through migration and diaspora, with individuals bearing this surname found in various countries today.
Demographics
Among Census respondents with the surname Rienecker, the largest self-reported group is White at 88.3%. The next largest groups are Hispanic (6.8%) and Two or More Races (3.9%).
The bar chart below shows how Rienecker 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 Rienecker 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.
