Origin
The surname RICHARZ is of German origin, tracing its roots back to the Middle Ages in regions of central and northern Germany. It is believed to have derived from the Old German word "riche," meaning wealthy or powerful, and the suffix "-arz," which was commonly used to indicate an occupation or characteristic.
One of the earliest recorded instances of the name dates back to the 13th century, when a person named Henrich Richarz was mentioned in a manuscript from the city of Cologne. This suggests that the name may have originated in the Rhineland region of Germany during that time period.
In the 14th century, there are records of a knight named Konrad Richarz who served under the House of Habsburg in Austria. This could indicate that the name had spread to other parts of the German-speaking territories by that point.
The name RICHARZ also appears in several historical documents from the late medieval and early modern periods, including tax records and property deeds from various cities and towns across Germany. One notable example is the mention of a merchant named Hans Richarz in a trade agreement signed in the city of Nuremberg in the year 1492.
Throughout the centuries, the name has undergone various spellings and regional variations, such as Richarz, Richarts, and Richardt. These variations were often influenced by local dialects and the preferences of individual record-keepers.
Some notable individuals who bore the surname RICHARZ include:
1. Georg Richarz (1592-1653), a German composer and organist who served as the Kapellmeister at the court of Saxony-Weimar.
2. Christoph Richarz (1637-1711), a German jurist and legal scholar who served as a professor at the University of Jena.
3. Johann Richarz (1720-1788), a German architect who designed several churches and public buildings in the Baroque style.
4. Wilhelm Richarz (1824-1892), a German politician and member of the Prussian parliament, known for his advocacy of workers' rights and social reforms.
5. Else Richarz (1868-1948), a German feminist and activist who campaigned for women's suffrage and equal rights in the early 20th century.
While the surname RICHARZ may have originated from a reference to wealth or status, it has been borne by individuals from various backgrounds and professions throughout history, reflecting the diverse experiences and contributions of those who carried this name.
Demographics
Among Census respondents with the surname Richarz, the largest self-reported group is White at 91.3%. The next largest groups are Two or More Races (5.2%) and Hispanic (2.6%).
The bar chart below shows how Richarz 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 Richarz 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.
