Origin
Meaning and origin of Agger
The surname Agger is of Danish origin, derived from the Old Norse word "agger," which means "ridge" or "bank." It was likely initially given as a descriptive name to someone who lived near a ridge or embankment, or whose property was located on such a geographical feature.
The earliest recorded instances of the Agger surname can be traced back to the 13th century in Denmark, where it appears in various medieval records and documents. One notable historical reference is the mention of a certain Niels Agger in the Danish Annals of 1286, where he is described as a landowner from the town of Randers.
In the 15th century, the surname Agger began to spread beyond Denmark to other parts of Scandinavia, particularly in Norway and Sweden. During this period, variations of the spelling emerged, such as Agger, Agger, and Aggere.
One of the earliest known bearers of the Agger surname was Hans Agger, a Danish merchant and ship owner who lived in the late 15th century. He is recorded as having traded extensively with the Hanseatic League, a powerful commercial and defensive confederation of merchant guilds and market towns in Central and Northern Europe.
Another notable figure was Peder Agger, a Danish theologian and reformer who lived from 1546 to 1611. He played a significant role in the Danish Reformation and was a vocal supporter of the Lutheran movement in Denmark.
In the 17th century, the Agger surname appeared in various records in the Netherlands, where it was likely introduced by Danish or Norwegian immigrants. One such example is Jens Agger, a Dutch merchant and trader who lived in Amsterdam in the mid-1600s.
Towards the end of the 18th century, the Agger surname began to spread to other parts of Europe and the Americas, as Danish and Norwegian families emigrated to new lands. One such individual was Hans Christian Agger, a Norwegian-born farmer who settled in Wisconsin, United States, in the late 1800s.
In more recent times, the Agger surname has been carried by several notable individuals, such as Danish architect and urban planner Jørn Utzon (1918-2008), who designed the iconic Sydney Opera House in Australia, and Danish football player Daniel Agger (born 1984), who played for several teams, including Liverpool FC in the English Premier League.
Demographics
Ancestry and ethnicity for Agger

The bar chart below shows how Agger 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 Agger surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
