Origin
Meaning and origin of Demich
The surname DEMICH is of Eastern European origin, specifically from the Slavic regions of modern-day Poland and Ukraine. It is believed to have emerged around the 15th century, derived from the Slavic personal name "Demian" or "Demetrius," which itself traces back to the Greek name "Demetrios."
The earliest known record of the DEMICH surname can be found in a Polish village registry from the late 1400s, where it was spelled "Dziemicz." This spelling variation likely reflects the phonetic adaptation of the name to the local dialect of the time.
In the 16th century, the DEMICH name appeared in various historical documents across Eastern Europe, including land records, tax registers, and court proceedings. One notable mention is found in a 1572 manuscript from the city of Lviv, which refers to a merchant named Andrzej DEMICH.
By the 17th century, the DEMICH surname had spread to other parts of Eastern Europe, including Belarus and Russia. In 1692, a record from the town of Minsk mentions a landowner named Ivan DEMICH.
Throughout the 18th and 19th centuries, several individuals bearing the DEMICH surname achieved recognition in various fields. For instance, Mikhail DEMICH (1779-1841) was a prominent Russian painter known for his portraits and historical scenes. Andrei DEMICH (1813-1878) was a Ukrainian scholar and linguist who made significant contributions to the study of Slavic languages.
Another notable figure was Katarzyna DEMICH (1848-1923), a Polish activist and writer who advocated for women's rights and education. Her husband, Józef DEMICH (1842-1901), was a respected lawyer and politician who served in the Galician Diet.
In the early 20th century, Stanisław DEMICH (1892-1967) was a Polish military officer who fought in both World Wars and received several decorations for his service.
Throughout its history, the DEMICH surname has maintained a strong presence in Eastern Europe, with various spellings and variations emerging across different regions and time periods. While its exact origins remain somewhat obscure, the name's enduring legacy is a testament to the rich cultural tapestry of the Slavic world.

The bar chart below shows how Demich 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 Demich surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
