Origin
The surname BAKUS is believed to have originated in the region of modern-day Lithuania and Latvia during the medieval period. It is likely derived from the Old Prussian word "bakus," which meant "marsh" or "swamp." This suggests that the name may have initially referred to someone who lived near a marshy area or worked as a trader or transporter navigating through these wetlands.
One of the earliest recorded instances of the name BAKUS can be found in the Prussian Chronicles, a historical text written in the 14th century. It mentions a landowner named Bakus von Memelburg, who held a estate near the town of Memel (now Klaipeda, Lithuania) in the late 13th century.
In the 16th century, a variant spelling of the name, "Backus," appeared in church records from the town of Raseiniai, Lithuania. This may indicate that the name had spread to other parts of the region by that time.
A notable bearer of the BAKUS name was Jonas Bakus, a Lithuanian merchant and philanthropist who lived in the late 17th century. He is credited with establishing a school and hospital in the city of Kaunas, which still bear his name today.
Another prominent figure was Petras Bakus, a Lithuanian military leader who fought against the Teutonic Knights in the 15th century. He is mentioned in several historical accounts of the time, including the Chronica Terrae Prussiae, for his role in defending the city of Vilnius.
In the 19th century, a family with the surname BAKUS emigrated from Lithuania to the United States, settling in the state of Pennsylvania. Among its members was Jonas Bakus (1832-1912), a farmer and community leader who helped establish a Lithuanian Catholic parish in the town of Shenandoah.
The BAKUS name has also been traced to the village of Bakussen (now Bakshtas) in western Lithuania, which may have been named after an early settler with this surname. This suggests that the name has deep roots in the region and may have originally referred to a specific location or geographic feature.
Demographics
Among Census respondents with the surname Bakus, the largest self-reported group is White at 88.6%. The next largest groups are Two or More Races (4.4%) and Hispanic (2.6%).
The bar chart below shows how Bakus 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 Bakus surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Bakus (2010, 2020).
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.
