Origin
Meaning and origin of Dealmeida
The surname DEALMEIDA originated in Portugal during the 12th century. It is derived from the Portuguese words "de" meaning "from" and "Almeida" which is a town in the Beira Alta region of central Portugal. The name signifies that the original bearer was a person who hailed from the town of Almeida.
The town of Almeida is situated near the Spanish border and has a long history dating back to Roman times when it was known as "Alameda". The name Almeida is believed to have evolved from this older Roman place name. During the Reconquista period in the 12th century, Almeida was an important frontier fortress town controlled by Portuguese knights.
One of the earliest recorded mentions of the surname DEALMEIDA can be found in a manuscript from the 14th century that documents the participation of a knight named João DEALMEIDA in the Battle of Aljubarrota in 1385, a pivotal conflict in the Portuguese struggle for independence from Castile.
Throughout history, there have been several notable individuals with the surname DEALMEIDA. One of the most renowned was Francisco DEALMEIDA (1450-1510), a Portuguese explorer and the first viceroy of Portuguese India. He played a crucial role in establishing Portuguese trading posts and colonies in the Indian Ocean region.
Another prominent figure was Lourenço DEALMEIDA (1480-1508), a Portuguese navigator and explorer who led one of the earliest European expeditions to Ceylon (modern-day Sri Lanka) in 1505. He is also credited with establishing the first Portuguese settlement in the island.
In the 16th century, Manuel DEALMEIDA (1520-1589) was a Portuguese Jesuit missionary who worked extensively in Japan and is revered as a martyr by the Catholic Church for his efforts in spreading Christianity in the region.
During the 17th century, João DEALMEIDA (1628-1691) was a renowned Portuguese painter who specialized in religious and mythological themes. His works can be found in various churches and museums throughout Portugal.
In the 19th century, José DEALMEIDA (1836-1914) was a prominent Brazilian politician and diplomat who served as the President of Brazil from 1902 to 1906, playing a significant role in shaping the country's political landscape during that period.

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.

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 Dealmeida surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
