Origin
The surname Araujo originates from Portugal and has its roots in the 12th century. It is derived from the Portuguese word "araujo," which means a small oak grove or a thicket of oak trees. This surname is primarily found in the northern regions of Portugal, particularly in the provinces of Minho and Trás-os-Montes.
One of the earliest recorded instances of the name Araujo can be found in the medieval Portuguese manuscript "Livro Velho das Linhagens" (Old Book of Lineages), which dates back to the 13th century. This document mentions several noble families bearing the surname Araujo, indicating their prominence during that era.
In the 14th century, a notable figure named João Araujo was a renowned Portuguese explorer who accompanied Ferdinand Magellan on his famous voyage around the world. He played a crucial role in navigating the treacherous Strait of Magellan, which now bears his name.
During the 15th century, the Araujo family established themselves as influential landowners in the region of Minho. The town of Araujo, located in the municipality of Ponte de Lima, is believed to have been named after this prominent family, further solidifying their legacy in the area.
The 16th century saw the rise of Pedro de Araujo, a celebrated Portuguese architect and engineer who designed several iconic buildings, including the magnificent Jerónimos Monastery in Lisbon. His contributions to architectural design and engineering left an indelible mark on the nation's cultural heritage.
In the 18th century, Manuel Araujo de Castro, a Portuguese diplomat and statesman, played a pivotal role in negotiating the Treaty of Madrid, which resolved territorial disputes between Portugal and Spain in South America. His diplomatic efforts helped shape the geopolitical landscape of the time.
As the Araujo surname spread beyond Portugal, it found its way to various parts of the world, including Brazil, where it became prevalent among Portuguese settlers and their descendants. Prominent figures bearing this surname include João Araujo Correia, a 19th-century Brazilian lawyer and politician who served as the President of the State of Pará.
Demographics
Among Census respondents with the surname Araujo, the largest self-reported group is Hispanic at 66.3%. The next largest groups are White (27.8%) and Black (2.7%).
The bar chart below shows how Araujo 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 Araujo 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 Araujo (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.
