Origin
Meaning and origin of Sitomer
The surname Sitomer is believed to have originated in Eastern Europe, specifically in the regions of modern-day Poland and Ukraine, during the late Middle Ages. It is derived from the Slavic root word "sito," meaning "sieve" or "strainer," suggesting that the name may have initially been an occupational surname for someone who made or used sieves.
One of the earliest recorded instances of the Sitomer surname can be found in the Galician region of Poland in the 16th century, where it was spelled "Sytomer." This variation in spelling was common during that time due to the lack of standardized orthography.
In the 17th century, the name Sitomer appeared in various tax records and land registers in the towns of Lviv and Ternopil, located in what is now western Ukraine. These records indicate that Sitomer families were involved in various crafts and trades, including metalworking and weaving.
A notable figure bearing the Sitomer surname was Jakub Sitomer, a prominent merchant and landowner who lived in the town of Berdychiv, Ukraine, in the late 18th century. Records show that he was a respected member of the local Jewish community and played a significant role in the town's economic development.
In the 19th century, as the Sitomer family dispersed throughout Eastern Europe and beyond, the name underwent further variations in spelling, such as "Sittomer" and "Zittomer." This was likely due to the influence of different languages and dialects in the regions where the name was adopted.
One of the earliest known Sitomers in the United States was Isaac Sitomer, who immigrated from Poland in the late 1800s and settled in New York City. He worked as a tailor and is recorded as having several children, many of whom anglicized their surname to "Sittomer."
Another notable figure was Shlomo Sitomer, a renowned rabbi and scholar who lived in Odessa, Ukraine, in the late 19th century. He was widely respected for his expertise in Jewish law and is remembered for his contributions to the local Jewish community.
Throughout the 20th century, the Sitomer surname continued to spread globally, with individuals bearing the name making contributions in various fields, including academia, business, and the arts.

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 Sitomer surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
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.
