Origin
The surname Sharkus is believed to have originated in the coastal regions of northern Portugal during the late 15th century. It is derived from the Portuguese word "sharko," which means "shark." This suggests that the name may have been given to someone who lived near the ocean and had a connection to fishing or maritime activities.
One of the earliest recorded instances of the name Sharkus can be found in a 16th-century maritime log from a Portuguese fishing vessel. The log mentions a crew member named Joao Sharkus, who was a skilled navigator and fisherman. This record provides evidence that the name was in use during this time period and was associated with seafaring occupations.
In the 17th century, the name Sharkus began to appear in various parish records and legal documents across northern Portugal. One notable individual was Maria Sharkus, born in 1632 in the coastal town of Viana do Castelo. She was known for her family's successful fishing business and her involvement in local trade and commerce.
As Portuguese explorers and settlers ventured to other parts of the world, the name Sharkus spread to different regions. In the 18th century, there are records of a man named Antonio Sharkus who was part of a Portuguese expedition to Brazil. He eventually settled in the coastal city of Salvador and established a successful fishing trade.
In the 19th century, the Sharkus name gained prominence in the Azores Islands, an autonomous region of Portugal. One of the most notable figures was Manuel Sharkus (1823-1892), a prominent whaling captain and ship owner based in the island of Faial. His exploits and success in the whaling industry brought recognition to the Sharkus name in the region.
Another significant individual was Joana Sharkus (1867-1932), a philanthropist and community leader from the island of Pico. She was instrumental in establishing several schools and hospitals, using her wealth and influence to improve the lives of the local population.
Throughout its history, the surname Sharkus has maintained a strong connection to maritime activities and coastal regions, reflecting its origins and the occupations of those who bore the name in earlier times.
Demographics
Among Census respondents with the surname Sharkus, the largest self-reported group is White at 92.4%. The next largest groups are Two or More Races (6.7%) and Black (1.0%).
The bar chart below shows how Sharkus 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 Sharkus 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.
