Origin
The surname DEFREITAS originates from Portugal and can be traced back to the 15th century. It is derived from the Portuguese word "freitas," which means "fringes" or "borders," suggesting that the name may have been given to someone who lived near a border or boundary.
The earliest recorded mention of the DEFREITAS surname can be found in Portuguese records from the 1400s. Some historians believe that the name may have been associated with Jewish families who fled from Spain during the Inquisition and settled in Portugal, adopting the surname DEFREITAS as a way to assimilate into Portuguese society.
In the 16th century, the DEFREITAS name appeared in several documents related to the Portuguese colonization of Brazil. One notable individual was Pedro de Freitas, a Portuguese explorer who was part of the expedition led by Martim Afonso de Sousa to establish the first permanent Portuguese settlement in Brazil in 1532.
During the 17th century, the DEFREITAS surname began to spread to other parts of the world as a result of Portuguese exploration and colonization. For instance, João de Freitas was a Portuguese soldier who fought in the Dutch-Portuguese War in Brazil in the 1640s.
In the 18th century, a prominent figure with the DEFREITAS surname was Joaquim José de Freitas, a Portuguese military engineer who played a significant role in the construction of fortifications in various Portuguese colonies, including Brazil and Mozambique.
Another notable individual was Tomás de Freitas, a Portuguese navigator and cartographer who was involved in mapping the coasts of Brazil and West Africa in the late 18th century.
In the 19th century, one of the most famous figures with the DEFREITAS surname was José Joaquim de Freitas, a Portuguese journalist and politician who was instrumental in the establishment of the liberal constitutional monarchy in Portugal.
As the DEFREITAS name spread across the globe, it underwent various spelling variations, such as Freitas, DeFreitas, and DeFretas, reflecting the influences of different languages and cultures.
Demographics
Among Census respondents with the surname Defreitas, the largest self-reported group is White at 59.6%. The next largest groups are Black (20.4%) and Hispanic (10.8%).
The bar chart below shows how Defreitas 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 Defreitas 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.
