One of the earliest recorded instances of the name appears in the Domesday Book of 1086, where it is spelled "Muslega" and refers to a place name in Staffordshire. Other early spellings include Museleie, Muselea, and Museley.
The name Mosley is closely associated with the village of Moseley in the West Midlands, which was first mentioned in the Domesday Book as "Muslei". It is believed that some of the earliest bearers of the surname may have originated from this area.

Oswald Mosley (1896-1980), the infamous British politician and founder of the British Union of Fascists, is perhaps the most well-known individual with this surname. His controversial political views and activities during the 1930s and World War II have made him a controversial figure in British history.
Another notable Mosley was Sir Oswald Mosley (1597-1675), an English politician and landowner who served as Lord Lieutenant of Staffordshire. He played a prominent role in the English Civil War, initially supporting the Parliamentarian cause before switching sides to the Royalists.
Michael Mosley (born 1957) is a contemporary British journalist, broadcaster, and former medical doctor. He is best known for his work on television shows such as "Trust Me, I'm a Doctor" and for popularizing the 5:2 diet.

Demographics
Among Census respondents with the surname Mosley, the largest self-reported group is Black at 50.9%. The next largest groups are White (39.2%) and Two or More Races (5.7%).
The bar chart below shows how Mosley 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 Mosley 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.
