Origin
The surname DESIMAS is believed to have originated in Spain during the 16th century. It is derived from the Spanish phrase "de simas," which translates to "of the ravines" or "from the chasms." This suggests that the name was likely associated with people who lived near or worked in areas with deep ravines or gorges.
One of the earliest recorded instances of the DESIMAS surname can be found in the Catalan region of Spain. In 1587, a document from the town of Vilanova i la Geltrú mentions a family with the surname DESIMAS. This document indicates that the family owned a small vineyard near a ravine, further solidifying the connection between the name and its geographical origins.
During the 17th century, the DESIMAS name began to spread beyond the Catalan region. In 1634, a man named Javier DESIMAS was recorded in the city of Seville, where he worked as a stonemason. This suggests that members of the DESIMAS family had started to migrate and establish themselves in other parts of Spain.
In the late 18th century, the DESIMAS surname made its way to the Americas. One of the earliest known individuals with this name in the New World was Juan DESIMAS, who was born in 1776 in Havana, Cuba. Juan DESIMAS later became a renowned sailor and explorer, participating in several expeditions to the Caribbean and the Gulf of Mexico.
Another notable figure with the DESIMAS surname was Emilia DESIMAS, a Spanish writer and educator who lived from 1845 to 1912. Emilia was born in Madrid and spent much of her life advocating for women's education and literacy. She authored several books and was a prominent figure in the early feminist movement in Spain.
In the 20th century, one of the most famous individuals with the DESIMAS name was the Mexican artist and sculptor, Miguel DESIMAS (1902-1984). Born in Guadalajara, Miguel DESIMAS is celebrated for his intricate stone carvings and monumental public sculptures, which can be found in various cities across Mexico.
While the DESIMAS surname may have originated in a specific region of Spain, it has since spread to various parts of the world, carried by individuals who have made significant contributions in fields such as exploration, literature, art, and education.
Demographics
Among Census respondents with the surname Desimas, the largest self-reported group is White at 93.1%. The next largest groups are Two or More Races (3.9%) and Hispanic (2.0%).
The bar chart below shows how Desimas 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 Desimas 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.
