In the realm of science, Thomas Davidson (1817-1885) was a Scottish-American philosopher and educator who founded the Glenmore Summer School of Philosophy, which attracted notable thinkers like William James and Josiah Royce.
The Davidson name has also been linked to various place names in Scotland, such as Davidsons Mains in Midlothian and Davidsons Croft in Aberdeenshire, suggesting the widespread presence of the surname across different regions.

Demographics
Among Census respondents with the surname Davidson, the largest self-reported group is White at 80.9%. The next largest groups are Black (10.0%) and Two or More Races (4.1%).
The bar chart below shows how Davidson 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 Davidson surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Davidson (2000, 2010, 2020).
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.
