Origin
The surname Rizo is believed to have originated in Spain, with its roots tracing back to the medieval period. It is derived from the Spanish word "rizo," which means "curly" or "curled." This suggests that the name may have initially been a descriptive nickname given to someone with curly hair.
One of the earliest known references to the surname Rizo can be found in the historical records of Castile, a region in central Spain, dating back to the 13th century. These records mention individuals bearing the name Rizo, suggesting that the surname had already established itself in certain parts of the Iberian Peninsula by that time.
In the 15th century, during the height of the Spanish Empire, the Rizo surname began to spread across various territories under Spanish control. Historical records from this era show the presence of Rizo families in regions such as the Canary Islands, the Caribbean, and parts of South America.
One notable individual with the surname Rizo was Juan Rizo, a Spanish explorer and navigator who participated in the conquest of Mexico alongside Hernán Cortés in the early 16th century. Juan Rizo played a significant role in the exploration and settlement of the Gulf of Mexico region.
Another prominent figure was Pedro Rizo, a Spanish military officer and governor who served in the Spanish colonies in the Americas during the late 16th century. He was appointed as the governor of Cartagena de Indias, a strategically important port city in modern-day Colombia, and held this position from 1597 to 1600.
In the 17th century, the Rizo surname gained further recognition with the birth of Juan Bautista Rizo y Guzmán (1612-1688), a Spanish poet and playwright from Seville. His literary works, including plays and poetry collections, were highly regarded during his lifetime and contributed to the cultural heritage of the Golden Age of Spanish literature.
Another prominent individual with the Rizo surname was Antonio Rizo y López (1790-1868), a Spanish military officer and politician who played a significant role in the Carlist Wars of the 19th century. He served as a general in the Carlist forces and was instrumental in several military campaigns during the conflicts.
In more recent times, the Rizo surname has continued to be present in various parts of the world, particularly in Spain, Latin America, and regions with significant Spanish influence. However, as mentioned earlier, this detailed report focuses on the historical origins and notable figures associated with the surname Rizo, rather than modern census data or recent records.
Demographics
Among Census respondents with the surname Rizo, the largest self-reported group is Hispanic at 93.2%. The next largest groups are White (5.5%) and Black (0.4%).
The bar chart below shows how Rizo 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 Rizo 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.
