Origin
The surname Astor traces its origins to the German towns of Walldorf and Hunsrück in the Rhineland-Palatinate region of Germany. It emerged around the 11th century, derived from the Old German words 'ast' meaning branch and 'or' meaning ridge or hill. The name likely referred to someone who lived near a prominent ridge with trees or branches.
One of the earliest recorded instances of the Astor surname appears in the Codex Laureshamensis, a medieval cartulary from the Lorsch Abbey in present-day Hesse, Germany. The document, dated around 1100 AD, mentions an Astor von Walldorf as a landowner in the region.
In the 13th century, a branch of the Astor family migrated to the town of Bedburg in North Rhine-Westphalia, where they established themselves as respected merchants and landowners. The name appears in various medieval records from the region, often spelled as 'Astoir' or 'Astore'.
The most famous historical figure bearing the Astor name was John Jacob Astor (1763-1848), a German-American businessman and investor who became one of the wealthiest people in the United States during his lifetime. Born in Walldorf, he immigrated to America in 1784 and made his fortune in the fur trade and real estate.
Another notable Astor was William Waldorf Astor (1848-1919), the grandson of John Jacob Astor and a prominent figure in British politics and society. He served as the United States Minister to Italy from 1882 to 1885 and was later made a British peer, taking the title Viscount Astor.
In the 16th century, the Astor family expanded their presence to the Netherlands, where the name was sometimes spelled 'Aster' or 'Astoor'. One notable figure from this branch was Isaac Astor (1591-1669), a Dutch merchant and ship owner who established trade routes between Holland and the Baltic region.
The Astor surname also has a long history in Spain, where it is believed to have been introduced by German merchants and traders during the Middle Ages. One of the earliest recorded instances of the name in Spain comes from the 14th century, when a certain Pedro Astor was mentioned in a legal document from the city of Seville.
Throughout its history, the Astor surname has been associated with wealth, entrepreneurship, and social prominence, particularly in the United States and Europe. While the name's origins can be traced back to the Rhineland region of Germany, it has since spread to various parts of the world and continues to be a prominent surname in many countries.
Demographics
Among Census respondents with the surname Astor, the largest self-reported group is White at 69.8%. The next largest groups are Hispanic (19.7%) and American Indian/Alaska Native (4.6%).
The bar chart below shows how Astor 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 Astor 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.
