Origin
The surname DEOLIVEIRA is of Portuguese origin, derived from the word "oliveira" which means "olive tree" in Portuguese. It is a locational surname, suggesting that the earliest bearers of the name likely lived near or had some connection with an olive tree or an olive grove.
The earliest known records of the surname DEOLIVEIRA can be traced back to the 13th century in Portugal. It is believed to have originated in the northern regions of the country, particularly in the areas around Porto and Braga, where olive cultivation was prevalent.
One of the earliest recorded instances of the name DEOLIVEIRA appears in a land grant document from the year 1297, which mentions a certain "João DEOLIVEIRA" as the recipient of a parcel of land in the vicinity of Guimarães, a city in northern Portugal.
In the 15th century, a notable figure bearing the surname DEOLIVEIRA was Fernão DEOLIVEIRA, a Portuguese explorer and navigator who accompanied Vasco da Gama on his voyage to India in 1497-1499. Fernão DEOLIVEIRA played a crucial role in this historic voyage, which paved the way for the establishment of the Portuguese maritime empire in the Indian Ocean.
Another prominent individual with the surname DEOLIVEIRA was Manuel DEOLIVEIRA (1506-1581), a Portuguese Catholic priest and historian who served as the Bishop of Angers in France. He was a prolific writer and is best known for his work "Historia Ecclesiastica," which chronicled the history of the Catholic Church in Portugal.
In the 18th century, José DEOLIVEIRA (1705-1783) was a renowned Portuguese painter and architect. He was responsible for the design and construction of several notable buildings in Lisbon, including the Church of Nossa Senhora das Necessidades.
During the 19th century, António DEOLIVEIRA (1819-1887) was a prominent Portuguese politician and statesman who served as the Prime Minister of Portugal from 1879 to 1881. He played a significant role in the country's political landscape during a turbulent period of its history.
Over the centuries, the surname DEOLIVEIRA has spread beyond Portugal to other parts of the world, particularly to countries with strong Portuguese cultural influences, such as Brazil, Mozambique, and Angola, among others.
Demographics
Among Census respondents with the surname Deoliveira, the largest self-reported group is White at 78.3%. The next largest groups are Hispanic (8.6%) and Black (6.7%).
The bar chart below shows how Deoliveira 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 Deoliveira 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 Deoliveira (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.
