Origin
The surname KWIEK is of Polish origin and dates back to the Middle Ages. It is derived from the Polish word "kwiek," which means "lively" or "agile." The name was likely given as a nickname to someone who was particularly energetic or quick-moving.
The earliest recorded instances of the KWIEK surname can be found in historical documents from the 15th century in the region of Lesser Poland, which was part of the Kingdom of Poland at the time. The name appears to have been particularly prevalent in the areas around the cities of Krakow and Tarnow.
One of the earliest known individuals with the KWIEK surname was Jan KWIEK, a merchant from Krakow who was mentioned in a trade register from the year 1472. Another notable figure was Mikołaj KWIEK, a soldier who fought in the Battle of Grunwald in 1410, one of the most significant battles in medieval Polish history.
In the 16th century, the KWIEK surname can be found in records from the town of Bochnia, located in the Małopolska region of southern Poland. A document from 1542 mentions a man named Stanisław KWIEK, who was a member of the local guild of salt miners.
During the 17th century, the name KWIEK appears to have spread to other parts of Poland, including the city of Poznań in the west and the town of Zamość in the east. A notable individual from this period was Marcin KWIEK, a scholar and professor at the Jagiellonian University in Krakow, who lived from 1628 to 1701.
In the 18th century, the KWIEK surname can be found in records from the town of Łowicz, located in central Poland. A document from 1782 mentions a man named Tomasz KWIEK, who was a landowner and local official.
Other notable individuals with the KWIEK surname throughout history include Józef KWIEK, a Polish composer and pianist who lived in the 19th century, and Władysław KWIEK, a Polish soldier and resistance fighter during World War II who was awarded the Virtuti Militari, Poland's highest military decoration.
Demographics
Among Census respondents with the surname Kwiek, the largest self-reported group is White at 95.2%. The next largest groups are Two or More Races (2.4%) and Black (1.2%).
The bar chart below shows how Kwiek 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 Kwiek 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.
