Origin
The surname SEKAS is believed to have originated in Lithuania, with its roots tracing back to the 16th century. The name is derived from the Lithuanian word "sekas," which means "follower" or "disciple." This suggests that the earliest bearers of this surname may have been individuals closely associated with religious or scholarly pursuits.
SEKAS is primarily concentrated in the northern regions of Lithuania, particularly around the cities of Kaunas and Šiauliai. Historical records indicate that the name first appeared in the parish registers of these areas during the late 1500s and early 1600s.
One of the earliest known references to the SEKAS name can be found in the chronicles of the Kaunas Cathedral, where a certain Jonas SEKAS was mentioned as a member of the clergy in the year 1612. Further records from the same period also indicate the presence of a family named SEKAS in the village of Kruonis, situated near the city of Kaunas.
In the 18th century, the SEKAS surname gained some prominence with the birth of Antanas SEKAS (1721-1796), a renowned Lithuanian scholar and linguist. His contributions to the study of the Lithuanian language and its preservation were significant, and he is considered one of the foremost intellectuals of his time.
Another notable figure bearing the SEKAS name was Juozas SEKAS (1819-1878), a poet and writer who played a vital role in the Lithuanian National Revival movement. His literary works, which often celebrated Lithuanian culture and traditions, were instrumental in fostering a sense of national identity among the people.
In more recent history, Kazys SEKAS (1903-1981) was a prominent Lithuanian-American artist and painter. Born in Lithuania, he immigrated to the United States in the 1920s and became known for his vibrant and expressive works, which often depicted scenes from his homeland.
The SEKAS surname can also be found in other variations, such as SEKAITIS and SEKACKAS, which are likely derived from the same root word and may have originated as patronymic forms of the name.
While the SEKAS name is not among the most common surnames in Lithuania, it has a rich history and has been borne by individuals who have made significant contributions to various fields, including literature, arts, and academia.
Demographics
Among Census respondents with the surname Sekas, the largest self-reported group is White at 92.4%. The next largest groups are Hispanic (3.8%) and Asian/Pacific Islander (1.9%).
The bar chart below shows how Sekas 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 Sekas 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.
