Origin
The surname Umanzor has its origins in the Central American country of El Salvador. It is derived from the Nahuatl language, which was spoken by the indigenous Pipil people who inhabited the region before the Spanish conquest.
Umanzor is believed to be a combination of two Nahuatl words: "umantzin," meaning "old one," and "tzor," meaning "to dig or make a hole." This suggests that the name may have originally referred to an occupation or activity related to digging or excavation.
One of the earliest known records of the Umanzor surname dates back to the 16th century, shortly after the Spanish colonization of El Salvador. It appears in a church register from the town of Suchitoto, where a man named Juan Umanzor was listed as a landowner.
During the colonial period, the Umanzor name was also found in various legal documents and land records, indicating that some families with this surname had achieved a certain level of prominence and wealth.
In the 19th century, a notable figure bearing the Umanzor name was José María Umanzor, a military officer who fought in the Salvadoran civil war against the Guatemalan forces of Rafael Carrera in the 1840s. He was born in 1810 and died in 1868.
Another prominent individual with the Umanzor surname was Manuel Umanzor Arrieta, a Salvadoran politician and diplomat who served as the country's Minister of Foreign Affairs in the early 20th century. He was born in 1873 and died in 1939.
In more recent history, one of the most well-known individuals with the Umanzor surname is Mauricio Umanzor, a Salvadoran-American artist and sculptor. His works have been exhibited in numerous galleries and museums across the United States and Latin America.
Other notable figures with the Umanzor surname include Julio Cesar Umanzor, a Salvadoran professional soccer player who played for various clubs in Central America and the United States in the late 20th century, and Rosa Umanzor, a Salvadoran human rights activist who fought for the rights of indigenous communities during the country's civil war.
Overall, the Umanzor surname has a rich history that can be traced back to the indigenous Nahuatl culture of pre-colonial El Salvador, and it has been carried by individuals from various walks of life throughout the centuries.
Demographics
Among Census respondents with the surname Umanzor, the largest self-reported group is Hispanic at 96.9%. The next largest groups are White (2.4%) and Black (0.4%).
The bar chart below shows how Umanzor 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 Umanzor 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.
