Origin
The surname Simoes originates from Portugal, dating back to the 12th century. It is derived from the given name Simão, which is the Portuguese form of the biblical name Simon. The name likely has its roots in the Hebrew word "shama," meaning "to hear" or "to listen."
In the 13th century, the name Simoes appeared in various Portuguese records and manuscripts, indicating its prevalence in the region during that time. One of the earliest documented instances of the surname can be found in the "Livro Velho de Linhagens" (Old Book of Lineages), a Portuguese genealogical record from the 13th century.
The name Simoes is closely associated with the town of Simões, located in the municipality of Viana do Castelo in northern Portugal. It is believed that the surname may have originated from this place name or vice versa, reflecting the connection between the name and the geographic region.
Notable figures throughout history who bore the surname Simoes include João Simoes, a Portuguese explorer who accompanied Vasco da Gama on his voyage to India in the late 15th century. Another prominent individual was Pedro Simoes, a 16th-century Portuguese architect renowned for his contributions to the architectural style known as Manueline.
In the 17th century, Luís Simoes da Silva was a celebrated Portuguese painter known for his religious works and portraits. During the same period, Miguel Simoes de Morais was a respected jurist and legal scholar who served as a judge in the Portuguese courts.
Moving into the 18th century, José Simoes de Carvalho was a notable Portuguese military commander who played a significant role in the Napoleonic Wars, particularly in the defense of Portugal against French invasion.
The surname Simoes has a rich history deeply rooted in Portuguese culture and tradition, with its origins dating back to the medieval period. Its prevalence and prominence in various fields, from exploration and architecture to the arts and law, testify to the enduring legacy of this surname throughout the centuries.
Demographics
Among Census respondents with the surname Simoes, the largest self-reported group is White at 87.9%. The next largest groups are Hispanic (7.4%) and Two or More Races (2.0%).
The bar chart below shows how Simoes 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 Simoes 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.
