Origin
The surname "LOIDA" is believed to have originated in the Lombardic region of northern Italy during the 8th century. It is derived from the Germanic root word "loit," which means "song" or "melody." The name is thought to have been initially used as a descriptive surname, referring to individuals who were skilled singers or musicians.
During the Middle Ages, the spelling of the name evolved from "Loita" to "Loida," as it spread across various regions of Italy. One of the earliest recorded mentions of the surname can be found in a medieval manuscript from the city of Mantua, dated around 1250, which lists a "Petrus de Loida" as a local landowner.
In the 14th century, the name gained prominence when a family of Loida nobles rose to power in the city-state of Verona. Notably, a certain Guido Loida served as a magistrate and diplomat in Verona between 1380 and 1412, and his descendants continued to hold influential positions in the region for several generations.
As the Italian Renaissance unfolded, the name spread further across Europe, particularly to Spain and Portugal, where it was adopted by certain families of Italian descent. In the 16th century, a Spanish explorer named Juan Loida was among the first Europeans to establish settlements in the Philippines, and the name has since become relatively common in that archipelago.
Notable individuals with the surname "Loida" throughout history include:
1. Girolamo Loida (1537-1592), an Italian composer and organist from Venice.
2. Beatriz Loida (1628-1705), a Portuguese noblewoman and patron of the arts.
3. Antonio Loida (1770-1834), an Italian painter and sculptor from Milan.
4. Josefa Loida (1821-1898), a Spanish educator and pioneer of women's education in Madrid.
5. Emilio Loida (1881-1957), an Italian-American architect who designed several notable buildings in New York City.
While the surname "Loida" is not among the most common in the world today, it has a rich history spanning multiple countries and centuries, reflecting the diverse cultural influences that have shaped its evolution over time.
Demographics
Among Census respondents with the surname Loida, the largest self-reported group is White at 91.7%. The next largest groups are Two or More Races (4.6%) and Hispanic (2.8%).
The bar chart below shows how Loida 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 Loida 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.
