Origin
The surname SWOL is believed to have originated in the Netherlands during the 16th century. It is thought to be derived from the Dutch word "zwol," which means "swollen" or "puffed up." This could suggest that the name was initially given as a descriptive nickname to someone who appeared to be large or stout in stature.
One of the earliest recorded instances of the SWOL surname can be found in the Dutch census records of 1567, where a family by the name of Swol was listed as residing in the town of Gouda. It is possible that this family may have taken their name from the nearby town of Zwol, which is now known as Zwolle.
In the 17th century, the SWOL surname began to appear in various historical documents across the Netherlands and surrounding regions. For example, a merchant named Jan SWOL was mentioned in a trade agreement between the Dutch East India Company and the Sultan of Aceh in 1641.
As the Dutch Colonial Empire expanded, the SWOL name spread to other parts of the world. In 1684, a man named Pieter SWOL was recorded as being part of a Dutch settlement in what is now Cape Town, South Africa.
One notable individual with the SWOL surname was Dirk SWOL, a Dutch artist born in 1718. He was known for his intricate landscape paintings and is considered one of the most prominent figures of the Dutch Golden Age of painting.
Another significant figure was Cornelis SWOL, a Dutch military officer who served in the Napoleonic Wars. He was born in 1785 and fought in several key battles, including the Battle of Waterloo in 1815.
In the 19th century, the SWOL surname began to appear more frequently in various parts of Europe, including Germany and Belgium. One example is Wilhelm SWOL, a German philosopher born in 1832, who wrote extensively on the concepts of existentialism and phenomenology.
As the SWOL family name continued to spread and evolve, it took on various spellings and variations, such as Swoll, Swolle, and Swole. However, the core meaning and origins of the name remained rooted in the Dutch language and culture.
Demographics
Among Census respondents with the surname Swol, the largest self-reported group is White at 96.4%. The next largest groups are Black (0.9%) and Hispanic (0.9%).
The bar chart below shows how Swol 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 Swol 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.
