Origin
The surname Michaelson is a patronymic name that originated in England during the medieval period. It is derived from the given name Michael, which has Hebrew origins and means "who is like God." The suffix "-son" denotes "son of," indicating that the name was initially used to identify the son of someone named Michael.
One of the earliest recorded instances of the name Michaelson can be found in the Domesday Book, a comprehensive survey of landholdings in England commissioned by William the Conqueror in 1086. The name appears as "Michaelissone," a variant spelling that reflects the evolving nature of surnames during that time.
In the 13th century, the name Michaelson was associated with various locations in England, particularly in areas with a strong Anglo-Saxon influence. For instance, the Hundredorum Rolls of 1273 mention individuals with the name residing in counties such as Oxfordshire and Gloucestershire.
Notable individuals bearing the Michaelson surname throughout history include:
1. Sir John Michaelson (c. 1480 - 1551), an English merchant and member of the Worshipful Company of Mercers in London.
2. William Michaelson (1623 - 1689), a prominent English Puritan minister and author of several religious works.
3. Mary Michaelson (1747 - 1825), a Scottish poet and writer known for her lyrical compositions celebrating the Scottish landscape.
4. James Michaelson (1802 - 1873), a British explorer and surveyor who conducted pioneering expeditions in central Africa and mapped vast regions.
5. Elizabeth Michaelson (1854 - 1927), an American educator and activist who advocated for women's rights and played a significant role in establishing educational opportunities for women in the late 19th century.
The Michaelson surname has also been associated with various place names throughout its history. For example, the village of Michaelston-le-Pit in Gloucestershire, England, was formerly known as "Michaelestonge" in medieval records, reflecting the influence of the name in that region.
As with many surnames, the spelling of Michaelson has evolved over time, with variations such as Michelson, Michelsen, and Michaelsen appearing in different geographical regions and historical records.
Demographics
Among Census respondents with the surname Michaelson, the largest self-reported group is White at 89.9%. The next largest groups are Hispanic (4.1%) and Two or More Races (3.2%).
The bar chart below shows how Michaelson 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 Michaelson 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 Michaelson (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.
