One of the earliest recorded instances of the surname Jan can be found in the Domesday Book of 1086, where it appears as "Jan" and "Janne." This suggests that the name was already in use by the late 11th century in England.

The surname Jan is also associated with several place names in England, such as Janville, which was derived from the Old French "Jan's ville," meaning "Jan's town." This suggests that some instances of the surname may have originated from these place names.

Demographics
Among Census respondents with the surname Jan, the largest self-reported group is Asian/Pacific Islander at 74.1%. The next largest groups are White (16.0%) and Two or More Races (5.6%).
The bar chart below shows how Jan 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 Jan 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.
