Origin
The surname DELALUZ has its origins in Spain, where it emerged in the early 16th century. It is derived from the Spanish phrase "de la luz," which translates to "of the light." This likely refers to either a physical location associated with light or a symbolic reference to enlightenment or guidance.
One of the earliest recorded instances of the DELALUZ surname dates back to 1532, when it appeared in a document from the town of Seville, then a part of the Spanish Empire. This document mentioned a certain Juan DELALUZ, who was a merchant involved in the lucrative trade between Spain and its colonies in the Americas.
During the 16th and 17th centuries, as Spain expanded its colonial empire, many families with the DELALUZ surname migrated to various parts of the Spanish-controlled territories. This included regions in present-day Latin America, such as Mexico, Peru, and Colombia.
In the 18th century, the DELALUZ name appeared in several historical records from the Spanish city of Cádiz. One notable individual was Rodrigo DELALUZ, a naval officer who served in the Spanish Armada and participated in various battles against the British and Dutch fleets.
As the DELALUZ surname spread across different regions, it evolved into various spellings and variations. In some parts of Mexico, for instance, the name was sometimes written as DELUZ or DELALUZE.
One of the most famous individuals with the DELALUZ surname was María DELALUZ, a prominent feminist and activist from Argentina who lived from 1879 to 1968. She played a crucial role in the women's suffrage movement and fought for equal rights and representation in her country.
Another notable figure was Pedro DELALUZ, a celebrated artist and painter from Colombia who lived from 1892 to 1972. His works, which often depicted scenes of rural life and indigenous cultures, are considered an important part of the country's artistic heritage.
In the 20th century, the DELALUZ surname gained recognition in the field of literature. José DELALUZ, a Cuban-American writer born in 1928, is known for his novels and short stories that explore themes of identity, exile, and the immigrant experience.
While the DELALUZ name originated in Spain, it has since been carried across continents and cultures, leaving an indelible mark on various aspects of history, from military endeavors to artistic and literary achievements.
Demographics
Among Census respondents with the surname Delaluz, the largest self-reported group is Hispanic at 95.3%. The next largest groups are White (3.4%) and Black (0.8%).
The bar chart below shows how Delaluz 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 Delaluz 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.
