One of the earliest recorded instances of the name Amonson can be found in the Norwegian Census Records of 1801, where it appears as "Amonsen." This spelling variation suggests that the name may have initially been a patronymic, meaning "son of Amon."

Demographics

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