Origin
Meaning and origin of Requarth
The surname Requarth is of German origin, tracing its roots back to the late 16th century. It is believed to have originated in the region of Bavaria, where it was likely derived from a combination of the German words "reich" meaning "rich" and "wart" referring to a lookout or guard post. This suggests the name may have initially referred to someone who lived near or worked as a guard at a wealthy estate or fortified location.
One of the earliest recorded mentions of the surname Requarth can be found in the church records of the town of Bamberg in 1587, where a Johannes Requarth is listed as a resident. The spelling variations at the time included Requardt, Reqwart, and Reqwarth, reflecting the evolving standardization of German surnames.
In the 17th century, a notable bearer of the name was Hans Requarth, a skilled blacksmith born in Nuremberg in 1629. His work on intricate ironwork and architectural details can still be seen in some of the city's historic buildings today.
The Requarth name also appeared in several regional tax records and land ownership documents from the 18th century, indicating the family's presence in various parts of southern Germany during this period.
One of the earliest documented instances of the Requarth name in the United States can be traced back to Johann Requarth, who immigrated from Germany to Pennsylvania in 1742, settling in the area that is now Berks County.
Other notable individuals with the Requarth surname throughout history include:
1. Wilhelm Requarth (1837-1909), a German painter and illustrator known for his landscapes and genre scenes.
2. Elise Requarth (1870-1953), a German-American opera singer and vocal instructor who performed with prominent opera companies in Europe and the United States.
3. Friedrich Requarth (1892-1970), a German architect and urban planner who played a significant role in the reconstruction efforts in Berlin after World War II.
4. Gerhard Requarth (1920-2003), a German athlete and Olympic silver medalist in the decathlon at the 1952 Summer Olympics in Helsinki.
5. Ingrid Requarth (born 1957), a German journalist and author who has written extensively on topics related to women's rights and gender equality.

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 Requarth surname at the time of the 2020 Census, not any inherent property of the name itself.

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.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
