Origin
The surname Nogueira originates from Portugal and is believed to have first emerged in the 12th or 13th century. It is derived from the Portuguese word "nogueira," which means "walnut tree." The name likely referred to someone who lived near a walnut tree or a place where walnut trees grew abundantly.
Nogueira is a toponymic surname, meaning it is derived from a place name. In this case, it may have been taken from one of several towns or villages in Portugal with the name Nogueira or a variation of it, such as Nogueira da Regedoura or Nogueira do Cravo.
The earliest recorded instance of the surname Nogueira can be found in the Livro Velho de Linhagens (Old Book of Lineages), a Portuguese genealogical manuscript from the 13th century. It mentions a nobleman named Mem Rodrigues Nogueira who lived during the reign of King Afonso III (1210-1279).
Another notable early bearer of the surname was João Afonso Nogueira, a Portuguese explorer and navigator who is credited with discovering the Cape Verde Islands in 1460. He was part of the early Portuguese expeditions along the West African coast, organized by Prince Henry the Navigator.
During the Age of Discovery, several Nogueiras were involved in the exploration and colonization of the Americas. One example is Pedro Álvares Nogueira, a Portuguese settler who established a sugar plantation in Brazil in the early 16th century.
In the 17th century, a prominent member of the Nogueira family was Tomás Nogueira, a Portuguese Jesuit missionary who worked in Japan and was martyred in Nagasaki in 1629.
Another notable figure was Manuel Nogueira de Gama, a 19th-century Portuguese nobleman and politician who served as Prime Minister of Portugal from 1827 to 1828.
Throughout history, the Nogueira surname has been found in various spellings, such as Noguera, Nogueyra, and Noguera de Ramoin. It has also been associated with certain place names in Portugal, such as Quinta da Nogueira (Walnut Farm) or Ribeira da Nogueira (Walnut Creek).
Demographics
Among Census respondents with the surname Nogueira, the largest self-reported group is White at 68.5%. The next largest groups are Hispanic (21.9%) and Black (4.6%).
The bar chart below shows how Nogueira 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 Nogueira surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Nogueira (2000, 2010, 2020).
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.
