Origin
The surname DELCI originates from Italy, with its roots tracing back to the 15th century. It is believed to have derived from the Latin word "deliciae," which means "delight" or "pleasure." This surname was likely given to someone who was considered a delightful or pleasant individual.
DELCI is predominantly found in the northern regions of Italy, particularly in the areas around Milan and Genoa. The earliest recorded instances of this surname can be found in various municipal records and documents from these areas during the Renaissance period.
One notable historical reference to the surname DELCI is found in the archives of the Archivio di Stato di Milano, which contains records of a family by the name of Delci from the late 16th century. These records provide insights into their involvement in local trade and commerce during that era.
In the 17th century, the surname DELCI appeared in several ecclesiastical records, indicating that members of this family were involved in the clergy. One such example is Lorenzo Delci, born in 1625, who served as a priest in the city of Genoa.
As the centuries progressed, the DELCI surname spread to other parts of Italy and beyond. In the 18th century, a notable figure bearing this surname was Antonio Delci, born in 1712, who was a renowned artist and painter from the city of Venice.
During the 19th century, the DELCI surname gained prominence in the literary world with the birth of Giulia Delci in 1842. She was a celebrated Italian poet and author, known for her works that explored themes of love, nature, and the human condition.
Another notable individual with the surname DELCI was Alessandro Delci, born in 1878, who was a prominent Italian politician and served as a member of the Italian Parliament during the early 20th century.
Over the centuries, variations of the DELCI surname have emerged, such as Delce, Delchy, and Delchio, reflecting regional dialects and linguistic influences. However, the core meaning and origin of the name remained rooted in the concept of delight and pleasure.
Demographics
Among Census respondents with the surname Delci, the largest self-reported group is Hispanic at 71.7%. The next largest groups are White (21.7%) and Black (2.8%).
The bar chart below shows how Delci 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 Delci 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.
