Origin
The surname Arnerich is believed to have originated in the Veneto region of northern Italy, likely during the medieval period. It is thought to derive from the Germanic personal name Arnrich, composed of the elements "arn" meaning eagle and "ric" meaning power or ruler. This suggests the name may have initially referred to someone with an eagle-like quality or someone in a position of authority.
One of the earliest known references to the name can be found in a 13th-century document from the city of Verona, which mentions an individual named Arnerico da Valpolicella. It's possible this was an early spelling variation of the surname Arnerich. The name also appears in records from the nearby towns of Vicenza and Padua during the 14th and 15th centuries.
In the late 15th century, a notable bearer of the name was Girolamo Arnerich, a wealthy merchant from Venice who established trade routes throughout the Mediterranean. His grandson, Sebastiano Arnerich (1520-1589), was a renowned humanist scholar and diplomat who served as the Venetian ambassador to the court of King Philip II of Spain.
Another prominent figure was Vincenzo Arnerich (1660-1734), a Venetian architect who designed several churches and palaces in his native city, including the Church of Santa Maria della Salute. His son, Antonio Arnerich (1695-1768), followed in his footsteps as an architect and helped rebuild parts of Venice after a devastating fire in 1744.
In the 19th century, Giuseppe Arnerich (1815-1892) was a respected Italian painter who specialized in portraiture and historical scenes. His works can be found in various museums and galleries throughout Italy.
Other notable individuals with this surname include Enrico Arnerich (1878-1942), an Italian poet and journalist who was part of the Futurist movement, and Giulio Arnerich (1899-1972), a World War I veteran and resistance fighter during World War II who was awarded the Italian Gold Medal of Military Valor for his bravery.
Demographics
Among Census respondents with the surname Arnerich, the largest self-reported group is White at 80.0%. The next largest groups are Hispanic (10.0%) and Asian/Pacific Islander (5.0%).
The bar chart below shows how Arnerich 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 Arnerich 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.
