Origin
The surname Suniga originated in Spain, with roots dating back to the Middle Ages. It is believed to have derived from the Basque word "suni," meaning fire or flame, coupled with the suffix "-ga," often used to denote a place of origin. This suggests that the name may have referred to a person or family associated with a location where fires or flames were prominent, such as a blacksmith's forge or a volcanic region.
One of the earliest recorded instances of the Suniga name appears in the Becerro de Behetrías, a medieval census of landholdings and settlements in the Kingdom of Castile, compiled in the 14th century. This document mentions individuals bearing the name Suniga residing in the region of Burgos, located in northern Spain.
In the 15th century, the Suniga family gained prominence as members of the Castilian nobility. Notably, Álvaro de Zúñiga y Guzmán (1410-1488) served as the Duke of Arévalo and played a significant role in the political intrigues surrounding the reign of Isabella I of Castile. His son, Álvaro de Zúñiga y Guzmán (1455-1531), also held influential positions as the Duke of Béjar and a member of the Royal Council of Castile.
The Suniga name has also been linked to various place names in Spain, such as Zuñiga, a municipality in the province of Navarre, and Zúñiga, a village in the province of Badajoz. These locations likely derived their names from the Suniga family or their ancestral lands.
Another notable figure bearing the Suniga surname was Juan de Zúñiga Avellaneda (1556-1631), a Spanish playwright and poet who authored several works, including the comedies "El amor invencionero" and "El hombre Dios."
In the realm of exploration and colonization, Diego López de Zúñiga (c. 1510-1564) was a Spanish conquistador who participated in the conquest of Peru alongside Francisco Pizarro. He later served as the governor of the Charcas region, now part of modern-day Bolivia.
While the Suniga name has its roots in Spain, it has since spread to other parts of the world, particularly Latin America, due to Spanish colonial expansion and migration patterns. Individuals bearing this surname can be found in various countries, including Mexico, Colombia, and Argentina, among others.
Demographics
Among Census respondents with the surname Suniga, the largest self-reported group is Hispanic at 80.3%. The next largest groups are White (9.3%) and Asian/Pacific Islander (8.5%).
The bar chart below shows how Suniga 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 Suniga 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.
