Origin
The surname Nieto is of Spanish origin and dates back to the medieval period. It is derived from the Spanish word "nieto," which means "grandson" or "descendant." The name likely originated as a descriptive nickname or surname given to someone who was the grandson or descendant of a notable person or family.
In Spain, the surname Nieto can be traced back to the 13th and 14th centuries. It was particularly common in regions such as Andalusia, Castile, and Extremadura. The earliest recorded examples of the name can be found in medieval documents and records, including parish registers and census records from that time period.
The Nieto surname has also been associated with several place names in Spain, such as Nieto de Cameros in La Rioja and Nieto de Molina in Guadalajara. These place names suggest that the surname may have originated from specific locations or estates where families with the name resided.
One of the earliest recorded individuals with the surname Nieto was Juan Nieto, a Spanish explorer and navigator who participated in the expeditions to the Pacific Northwest in the late 17th century. Another notable figure was Pedro Nieto y Castilla (1631-1704), a Spanish architect and sculptor who designed several churches and buildings in Madrid and Valladolid.
In the 16th century, the Nieto family played a significant role in the Spanish conquest and colonization of the Americas. Juan Nieto Polo (1504-1590) was a conquistador who accompanied Hernán Cortés in the conquest of Mexico and later became one of the founders of the city of Puebla.
Other notable individuals with the Nieto surname include José Nieto (1815-1900), a Mexican politician and diplomat who served as the Minister of Foreign Affairs in the 19th century, and Manuel Nieto (1784-1876), a Spanish-Mexican soldier and rancher who was granted a land grant in what is now Los Angeles County, California.

Demographics
Among Census respondents with the surname Nieto, the largest self-reported group is Hispanic at 90.0%. The next largest groups are White (7.3%) and Asian/Pacific Islander (1.0%).
The bar chart below shows how Nieto 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 Nieto 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.
