Origin
The surname Novajosky originates from the Czech Republic and can be traced back to the early 16th century. It is believed to have derived from the Czech word "novajoksa," which translates to "new settler" or "newcomer." This suggests that the name was likely given to individuals or families who had recently migrated to a particular region or village.
One of the earliest recorded instances of the surname Novajosky can be found in a village census from the town of Litomerice, located in the modern-day Ustecky region of the Czech Republic. This census, dated 1532, lists a family by the name of Novajosky as residents of the village.
In the late 16th century, the Novajosky name appeared in several land ownership records in the Moravian region of the Czech lands. These records indicate that members of the Novajosky family were landowners and likely involved in agricultural pursuits.
During the 17th century, the surname Novajosky became more widespread throughout various regions of the Czech lands, including Bohemia and Moravia. One notable individual bearing this name was Jan Novajosky (1612-1687), a prominent merchant and landowner from the town of Olomouc.
In the 18th century, the Novajosky surname was found in various church records and parish registers across the Czech lands. One such record mentions a Vaclav Novajosky (1735-1802), who served as a village magistrate in the town of Kutna Hora.
As the 19th century dawned, the Novajosky name continued to be prevalent in various regions of the Czech lands. Karel Novajosky (1812-1878), a notable scholar and educator from Prague, was a significant figure during this era.
Throughout the centuries, the Novajosky surname has undergone minor variations in spelling, such as Novajovsky, Novajowsky, and Nowajowsky, but the core meaning and origin have remained consistent.
Demographics
Among Census respondents with the surname Novajosky, the largest self-reported group is White at 92.8%. The next largest groups are Two or More Races (6.3%) and Asian/Pacific Islander (0.9%).
The bar chart below shows how Novajosky 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 Novajosky 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.
