Origin
The surname Ol has its origins in Old Norse, with the earliest known examples dating back to the 9th century in Norway and parts of modern-day Sweden. The name is derived from the Old Norse word "olr", meaning "ancestral" or "heritage". It was likely used as a descriptive name to indicate someone of noble or ancient lineage.
Records from the Viking Age indicate that the name was present in various parts of Scandinavia, particularly in coastal regions where Norse settlers and traders had established settlements. Some of the earliest recorded instances of the name can be found in runic inscriptions and medieval Norwegian manuscripts from the 11th and 12th centuries.
One notable historical figure bearing the surname Ol was Olaf Ol Stigsson, a Norwegian chieftain and landowner who lived in the late 11th century. He was a prominent figure in the region of Trøndelag and is mentioned in the Icelandic sagas as a wealthy and influential individual.
In the 13th century, the name Ol appeared in the Domesday Book, a comprehensive record of land ownership and taxation in England commissioned by William the Conqueror in 1086. This suggests that individuals with the surname Ol may have been among the Norse settlers who migrated to parts of England during the Viking Age.
Another significant figure with the surname Ol was Olaf Ol Haraldsson, a Norwegian king who reigned from 1015 to 1030. Known as Olaf the Holy, he played a pivotal role in the Christianization of Norway and is celebrated as a martyr and saint in the Lutheran and Catholic traditions.
In the 14th century, the name Ol was found in various parts of Scotland, possibly brought by Norse settlers from the Shetland and Orkney Islands. One notable individual from this period was Ragnhild Ol, a Scottish noblewoman who lived in the late 14th century and was known for her involvement in land disputes and legal battles over inheritance rights.
Throughout the centuries, the surname Ol has undergone various spelling variations, such as Oll, Olle, and Olle, often reflecting regional dialects and linguistic influences. However, the core meaning and significance of the name have remained tied to its Norse origins, reflecting a sense of ancestral heritage and noble lineage.
Demographics
Among Census respondents with the surname Ol, the largest self-reported group is Asian/Pacific Islander at 29.5%. The next largest groups are White (23.8%) and Hispanic (16.2%).
The bar chart below shows how Ol 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 Ol 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.
